Foreword
China’s Tibet Autonomous Region is
situated on the main body of the Qinghai-Tibet Plateau. With
high altitude, unique geographical features and rich
wildlife, water and mineral resources, it has been called
the “Roof of the World” and the “Third
Pole of the Earth.” It is not only the “source
of rivers” and the “ecological source” for
the areas in South and Southeast Asia, but is also the
“starter” and “regulating area” of
the climate of China and indeed of the Eastern Hemisphere as
a whole.
The Chinese government attaches great
importance to ecological improvement and environmental
protection in Tibet. It has made tremendous efforts to
strengthen ecological improvement and environmental
protection work in Tibet, promote the sustainable
development of its economy and society, and improve the
quality of life of the people of its various ethnic groups.
For over half a century, ecological improvement and
environmental protection in Tibet, as an important part of
the effort to modernize Tibet, has, together with economic
development, social progress and enhancement of
people’s living standards, pressed forward and made
great achievements. It would help clarify some
people’s misunderstanding concerning Tibet’s
eco-environmental problem and enhance their understanding of
Tibet to review the progress of the ecological improvement
and environmental protection work in Tibet, to present the
status quo of this undertaking, and to envisage the
prospects of sustainable development for the region.
I. Progress of the Ecological Improvement and
Environmental Protection Work in Tibet
The
Tibet Autonomous Region is 1.22 million sq km in area, with
an average altitude of well over 4,000 m above sea level. It
boasts a unique natural ecology and geographical
environment. The climate in Tibet turns gradually from being
warm and moist to cold and dry from its southeast toward its
northwest. Ecologically, the changes are manifested in belts
from forest, bush, meadow and steppe to desert. The complex
and varied terrains and landforms as well as the unique type
of ecological system have created a natural paradise for
biodiversity.
The old Tibet before the 1950s
had long been under the rule of feudal serfdom. The
development level of its productive forces was extremely
low, and it was, by and large, in a state of passive
adaptation to natural conditions and one-way exploitation of
natural resources. It was absolutely impossible to discuss
the objective law of the ecological environment of Tibet, or
to talk about ecological improvement and environmental
protection. From the latter half of the 19th century, some
foreign explorers and scientists conducted various surveys
and investigations on the Qinghai-Tibet Plateau. In the
1930s, Chinese scientists also carried out some surveys and
investigations there. But, generally speaking, their
knowledge of the unique natural eco-environment of the
Qinghai-Tibet Plateau was incomplete and unsystematic.
It was after the peaceful liberation of Tibet
that ecological improvement and environmental protection
started there, and began to progress along with the
modernization of Tibet.
The peaceful
liberation initiated the process of scientific
understanding, voluntary protection and active improvement
of the ecological environment in Tibet. Shortly after the
peaceful liberation of Tibet in 1951, in order to unveil the
mysteries of the Qinghai-Tibet Plateau and promote
Tibet’s social progress and development, the Central
People’s Government organized the “Tibet Work
Team of the Government Administration Council” (on the
basis of which the “Tibet Comprehensive Exploration
Team of the Chinese Academy of Sciences” was
established in 1958), to explore and assess land, forest,
pastureland, water conservancy and mineral resources in
Tibet. The work team put forward a proposal for scientific
development and utilization, which started the process of
scientific understanding, utilization and protection of the
ecological environment in Tibet. At the same time,
ecological improvement and environmental protection work
gradually unfolded, with the aim of improving the
subsistence conditions on the Tibet Plateau. The State sent
forestry specialists to explore parts of the Yarlungzangbo
River Valley, and carried out experiments in the cultivation
of tree saplings and afforestation at the July 1 Farm in the
western suburbs of Lhasa, which laid the foundation for
large-scale afforestation and ecological improvement in
Tibet. After the implementation of the Democratic Reform in
1959, a mass voluntary tree-planting drive using local tree
species as the main breeds was launched in a big way in
Tibet. Such afforestation efforts enabled the Tibetan people
to achieve a qualitative leap from the centuries-old passive
adaptation to natural conditions to remaking nature on their
own initiative.
After the founding of the
People’s Government of the Tibet Autonomous Region in
September 1965, ecological improvement and environmental
protection were put on government agenda and thus
organizationally guaranteed, along with the progress of work
in all spheres achieved by the people’s democratic
government. In 1975, the Leading Group for Environmental
Protection of the Tibet Autonomous Region and its General
Office were established. In 1983, the Urban and Rural
Construction and Environmental Protection Department under
the government of the Autonomous Region was established.
Since then, the organizational structure and administrative
systems have kept improving, and ecological improvement and
environmental protection work in Tibet has gradually got
onto the track of sound development.
The
comprehensive scientific surveys on the Qinghai-Tibet
Plateau have helped people to learn about Tibet’s
natural eco-environment in a more systematic and profound
manner. As a result, ecological improvement work in Tibet
began to make substantial headway. The Chinese Academy of
Sciences formulated the “Comprehensive Scientific
Survey Plan for the Qinghai-Tibet Plateau for
1973-1980.” In 1972, the Academy held the
“Symposium on Scientific Survey in the Mt. Qomolangma
Area,” the first ever, in Lanzhou. In the wake of this
symposium, all types of comprehensive or specialized
academic conferences in respect of the natural
eco-environment of the Qinghai-Tibet Plateau were held one
after the other, accompanied by a large number of academic
achievements. The Qinghai-Tibet Plateau Comprehensive
Scientific Survey Series alone contains 31 titles in 42
volumes, amounting to a grand total of some 17 million
characters. These scientific achievements have provided a
scientific basis for making better use of natural resources
in the economic development of Tibet, and for continuous
improvement of the human living environment. In 1977, the
Ministry of Agriculture and Forestry organized for the first
time an all-round survey of the forestry resources across
Tibet. Since 1978, to meet the requirements of
afforestation, some 50 sapling farms have been set up in
various places, introducing, naturalizing and cultivating
scores of tree breeds suitable for Tibet.
The
reform and opening-up has enabled ecological improvement and
environmental protection work in Tibet to progress in a
law-governed manner. After the reform and opening policy was
adopted some two decades ago, as Tibet has grown more
modern, greater attention has been given to the Autonomous
Region’s ecological improvement and environmental
protection, which is progressing steadily in a law-governed
manner. In the 13 years from 1982 to 1994, the Standing
Committee of the People’s Congress of the Tibet
Autonomous Region, and the People’s Government of the
Tibet Autonomous Region and its various departments enacted
and implemented more than 30 relevant local regulations,
governmental standardization documents, and departmental
rules and regulations, which formed a relatively systematic
local legal regime concerning environmental protection. As
far as the contents were concerned, they included
comprehensive regulations concerning ecological and
environmental protection, such as the “Regulations for
Environmental Protection in the Tibet Autonomous
Region,” as well as special regulations for different
areas of ecological and environmental protection, such as
land management, mineral resources administration, forest
protection, grassland protection and control, water and soil
conservation, wild animals protection, nature reserves
administration, and pollution treatment. These rules and
regulations covered almost all areas in ecological and
environmental protection, so that there were laws to go by
in all these spheres.
The State has directly
invested in comprehensive agricultural development projects
on the middle reaches of the “three rivers” (the
Yarlungzangbo, Lhasa and Nyangqu rivers), with the emphasis
on the improvement of the ecological environment, and has
achieved noticeable ecological results. With regard to
tree-planting and grass-growing on barren mountains,
hillsides and beaches, the government has enacted a special
policy featuring “the lasting and inheritable practice
of whoever reclaims the land shall be entitled to operate
and get benefit from it.” This has encouraged local
people to plant trees and grow grass, and guaranteed the
rights and interests due to them in eco-environmental
amelioration. Investigations on the current status of the
ecological environment in the areas of land, wild fauna and
flora, plant, insect and wetland resources have been
successfully carried out. Eco-environment researchers have
begun to monitor and trace the impact of human activities on
the ecological environment, carried out various projects
such as dynamic remote-sensing monitoring of the
eco-environment for comprehensive agricultural development
on the middle reaches of the “three rivers,”
overall survey of the grain pollution caused by residual
organochlorine, and investigation on the sources of
industrial pollution, and have proposed relevant policies
and measures for pollution prevention and control.
Publicity and education concerning ecological
improvement and environmental protection have been widely
carried out, striking deep roots in the hearts of the
people. The media, including radio, television, newspapers
and the Internet, have given wide coverage to afforestation,
wild animals and plants preservation, and environmental
protection. Important commemorative events, such as World
Wetlands Day, Arbor Day, Earth Day, World Environment Day
and World Desertification and Drought Control Day have drawn
the attention of people from all walks of life in Tibet.
Lessons on ecological improvement and environmental
protection are given in schools, and an effort to establish
“green schools” is in full swing.
Concern from the Central Government and
support from people throughout the country have enabled
Tibet to embark upon a new phase in its ecological
improvement and environmental protection undertakings. The
Central Government called the Third Forum on Work in Tibet
in 1994, and made an important decision to extend the
support of the whole nation to Tibet under the care of the
Central Government, which has given a powerful impetus to
accelerating the ecological improvement and environmental
protection work there.
Since the 1990s, the
State Environmental Protection Administration has organized
environmental protection departments throughout the country
to support Tibet in enhancing its environmental protection
capability, helped build environment monitoring stations in
the Autonomous Region, in the cities of Lhasa and Xigaze and
in Qamdo Prefecture, helped train large numbers of technical
and administrative personnel in the field of environmental
protection, and helped formulate an ecological protection
and pollution control plan. In the “National Plan for
Eco-environmental Improvement” and the “National
Program for Eco-environmental Protection” formulated
by the State Council respectively in 1998 and 2000, great
attention has been paid to ecological improvement and
environmental protection in Tibet, and a separate plan has
been drawn up to make the freeze thawing zone on the
Qinghai-Tibet Plateau one of the country’s eight major
areas for ecological improvement, complete with the
proposition of a suite of explicit tasks and principles for
work in this regard. On the basis of this, the
People’s Government of the Tibet Autonomous Region
formulated the “Eco-environmental Improvement Plan of
the Tibet Autonomous Region” in 2000, which has
provided an overall program and arrangement for
Tibet’s eco-environmental improvement. After the State
decided to adopt the great western development strategy, the
Central Government held the Fourth Forum on Work in Tibet in
2001, and further increased investment in ecological
improvement projects in Tibet. From the perspective of
attaining sustainable development in Tibet, it has been
expressly stipulated that tourism and green agriculture be
developed as the pillar industries for promoting economic
growth in Tibet.
The State has increased its
input in ecological improvement and environmental protection
in Tibet, and intensified supervision on the law enforcement
connected with the ecological environment. Statistics show
that since 1996 the total investment contributed by the
Central Government in items concerning ecological
improvement in Tibet has come to RMB 368 million. At the
same time, a plethora of ecological engineering projects,
such as natural forest protection, restoration of farmland
to forest and pasture, afforestation in Lhasa and its
vicinity, wildlife protection, and nature reserves
construction, have been put into operation, which have
effectively improved the eco-environment in Tibet.
Ecological improvement and environmental
protection work, which had nothing to start with in Tibet,
has grown incessantly in the past half century or more, and
has undergone a process from voluntariness to
conscientiousness, from passiveness to activeness, and from
an unplanned to a scientific approach. According to the
bulletin on the eco-environmental situation published by the
relevant State authorities in 2000, the environmental
quality in Tibet is in a sound state, and most parts are
basically in a primordial state. Tibet is one of the best
areas in the world as far as natural environment is
concerned.
II. Ecological Improvement and
Biodiversity Protection
The positive
efforts made by the Tibet Autonomous Region for ecological
improvement and biodiversity protection in the past five
decades or more have been crowned with signal success.
Natural grassland is rationally utilized and
the active grassland ecological protection is effective.
Tibet contains one of the five largest pasturelands in
China. It has 82.07 million ha of natural grassland,
representing about 21% of the total natural grassland of the
country and 68.11% of the total land area of Tibet.
According to the first national survey of grassland
resources, the variety of grassland in Tibet ranks first
among all provinces and autonomous regions. Of the 18 types
of grassland in the country, Tibet has 17. To protect the
grassland ecology is an important link in preserving a
complete and orderly chain of ecology on the Qinghai-Tibet
Plateau.
Though the grassland area in Tibet is
very large, its carrying capacity is low. Grassland overload
was not significant in the old days in Tibet, because of
stagnant population growth, frequent natural calamities, and
massive human and livestock deaths in times of snowstorms
and other natural disasters. Since the peaceful liberation
of Tibet, the average life-span of the local population has
expanded remarkably, the population has kept increasing, and
as a result the issue of insufficient grass to feed the
ever-growing livestock population has begun to appear.
Consequently, to keep an ecological balance on the
pastureland has gradually become a prominent problem. To
ease the contradictions between human beings and farm
animals and between grass supply and farm animals, Tibet has
taken a succession of measures to strengthen the rational
utilization and ecological protection of natural grassland.
First, emphasis has been placed on fencing and building
water conservancy projects on natural grassland, and raising
both the output level of grassland and its carrying capacity
per unit area. Secondly, a pasture responsibility system has
been implemented. In line with the principle of limiting the
number of grazing animals by the size of the pasture,
rotation grazing periods, rotation grazing areas and
“no-grazing areas” have been designated. Efforts
have been made to increase the market availability rate of
the livestock and to effectively protect natural pastures by
strictly prohibiting over-grazing. Thirdly, man-made
grassland is being promoted so as to ease the pressure
brought to bear on natural grassland by the ever-growing
livestock population. Fourthly, efforts are being
intensified to prevent or control hazards caused by mice,
insects and poisonous weeds, and to maintain the natural
ecological balance of the grassland by utilizing scientific
means, and artificial and biological technologies. Fifthly,
to enhance grassland amelioration in the pastoral areas,
change the nomadic way of production, speed up economic
development in pastoral areas and improve herdsmen’s
living standards, projects to construct grassland in the
pastoral areas, build permanent settlements for roving
herdsmen, and restore and improve natural grassland have
been launched since 2001. These measures not only have
steadily raised the income of farmers and herdsmen and
enhanced their living standards, but also ensured the sound
development of the grassland ecology.
Protecting natural forest resources, carrying
out afforestation and improving the ecological environment.
Tibet boasts 7.17 million ha of forest, and the stocking
volume has reached 2.091 billion cu m. Tibet has the largest
primitive forest in China. To protect Tibet’s
ecological environment, the government exercises a
“felling by quota” policy, and strictly controls
the scale of tree-felling in forests. The annual felling
amount for commercial purpose is limited to 150,000 cu m.
Simultaneously, a rotation system is in place for lumbering
bases so as to help restore vegetation. A project for the
protection of natural forest resources on the upper reaches
of the Yangtze River in Tibet, with a total area of 31,000
sq km, has been implemented in the three counties of Jomda,
Gonjo and Markam that have a weighty bearing on the ecology
of the lower Yangtze valley. In 28 counties along the upper
reaches of the Jinsha, Lancang and Nujiang rivers and the
catchment area of the Yarlungzangbo River, where the hazards
of sandstorm and soil erosion are serious, a project to
restore farmland to forest is being undertaken, under which
52,000 ha of cultivated land will be restored to forest and
trees planted on 53,000 ha of barren mountains and
wasteland. By 2002, some 6,700 ha of cultivated land had
been restored to forest and 6,700 ha of barren mountains and
wasteland afforested. The government is also striving to
promote the development of energy substitutes and fuel
forests, and popularize solar energy in order to protect
natural bush vegetation.
It has become the
conscious action of the Tibetan people to join afforestation
efforts. The government of the Tibet Autonomous Region has
formulated the “Forestation Plan of the Tibet
Autonomous Region” and the “Opinions on
Acceleration of Afforestation.” The people of the
whole region are making efforts by starting with the
improvement of their living environments, first of all by
greening their courtyards, streets and urban environment in
general, and eventually building green belts in river
catchment areas where human activities are concentrated, and
along major highways. The results have been remarkable.
According to a survey, over the past 50-plus years some
70,000 ha of land have been afforested in Tibet, 90 million
trees have been planted beside villages, houses, roads and
waterways, and 1.5 million cash trees have been grown.
Afforestation and ecological projects
have been launched steadily. Implementation of the key
projects, such as the afforestation project in Lhasa and its
outskirts, the construction of the shelter-forest system of
the Yarlungzangbo River, the pilot project of the Yangtze
River shelter-forest system in Markam and the pilot project
for controlling sand by afforestation in Xigaze, has, to a
great extent, improved the natural eco-environment of those
localities. Since 1996, the State has begun to build a
shelter-forest system along the upper and middle reaches of
the Yangtze River. By 2000, it had invested more than 3.7
million yuan in the project, actively supporting Tibet in
building man-made forests and sealing off mountainous areas
to facilitate afforestation as appropriate to local
conditions. The afforested area has topped 13,000 ha, which,
as a result, has played a positive role in improving local
residents’ working and living conditions. Following
implementation of the project for the construction of the
shelter-forest system of the Yarlungzangbo River, which is
part of the key “three rivers” agricultural
development undertaking, a man-made forest belt measuring
several hundred km from Xigaze to Zetang on the upper
reaches of the Yarlungzangbo River has been formed. Now, a
new spectacular scene, the belt plays a positive role in
conserving water and topsoil along the Yarlungzangbo River.
Due to the effective protection of natural
forest resources and afforestation, the forest coverage in
Tibet has kept growing. It has grown from less than 1% in
the 1950s to 5.93% today, and has played a positive role in
improving the Autonomous Region’s ecological
environment. According to reports from relevant monitoring
departments, due to the increase in man-made vegetation, the
number of sandstorm days has decreased noticeably in Tibet.
Currently, it is 32 days fewer in Lhasa, 34 days fewer in
Xigaze and 32 days fewer in Zetang, than 30 years ago.
Comprehensive control of soil erosion has
brought noticeable achievements. The Tibet Plateau belongs
to the alpine cold meadow and steppe landscape, which is
characterized by poor water and soil conservation and
vulnerability to serious soil erosion. Over the past 50
years, soil erosion has been effectively controlled by
afforestation and construction of water conservancy
projects. In recent years in particular, the State and the
Tibet Autonomous Region have increased their investment in
soil erosion control, which has yielded highly desirable
results. By the end of 2001, the State had invested more
than 36.8 million yuan in Tibet, built 53,000 ha of forests
to conserve water and topsoil, grown grass on 67,000 ha,
harnessed soil erosion on 1,166 sq km, and launched a
comprehensive control project in the Radoigou small
catchment area in Quxu County, Lhasa, and implemented
comprehensive control projects for conserving water and
topsoil in Gyangze and Nyemo counties. Simultaneously, the
Tibet Autonomous Region has formulated the “Plan for
Conservation of Water and Topsoil in Tibet” and
several other plans in respect of water and soil
conservation and soil erosion control, promulgated the
“Measures of Administration for Water and Soil
Conservation Projects in the Tibet Autonomous Region,”
and made prevention, supervision and protection the top
priority of the water and soil conservation work, in order
to prevent new soil erosion caused by human activities. To
enable the comprehensive control of soil erosion to be
carried out in a more scientific way, the Tibet Autonomous
Region launched, in 2001, the construction of a water and
soil conservation monitoring network with an investment of
more than 60 million yuan to provide overall monitoring for
soil erosion across Tibet.
Achievements have
been made in desertification prevention and control.
Sandstorms have afflicted Tibet throughout its history. Now,
as a result of the expansion of the hole in the ozone layer
caused by global warming, Tibet has been facing problems of
rising snowlines, dried-up lakes, and deteriorated grassland
in recent years. In some areas in Tibet, pastureland has
suffered a natural deterioration, and some of it has been
reduced to sand and stone. To control pastureland
deterioration and desertification, Tibet has begun to
improve the environment of its rivers, with the emphasis on
improving small river valleys and the desertification of
deteriorated pastureland. With the goal of establishing a
relatively good ecological system of forestry and grassland,
Tibet has adopted measures consisting of afforestation,
aerial sowing and closing off hillsides to facilitate
afforestation. It has planted trees, bushes and grass on a
large scale near rivers and in areas that have been hit most
seriously by pastureland deterioration and desertification.
Projects to protect the natural forests and wetlands, and to
reconvert farmland into forest or pasture have been carried
out on the upper reaches of the Yangtze River. In 2002, the
goal was to reconvert some 13,000 ha of farmland into
forest. The Central Government provided 10 million yuan as
subsidy for seedlings, and 15 million kg of grain and two
million yuan as allowance for families of farmers and
herdsmen whose farmland had been restored to forest. Trees
were planted in the vicinity of Lhasa, and in important
agricultural areas forest shelter belts were built around
the fields to reduce soil erosion by sand. These measures
have brought the ever-expanding desertification threat under
control.
Great progress has been made in
protection of biodiversity. Tibet is one of the most
typically biodiverse regions in the world. It is an
important gene pool for the biodiversity of the globe. At
present, there are over 9,600 wild plants in Tibet, 39 of
which are listed in the Convention on International Trade in
Endangered Species of Wild Fauna and Flora and are under
special State protection as rare and endangered species.
There are 798 species of vertebrates and nearly 4,000
species of insects in Tibet, 125 of which are under special
State protection, accounting for more than one third of the
wild animals under special State protection. Approximately
600 species of higher plants and more than 200 species of
terrestrial vertebrates are endemic to the Qinghai-Tibet
Plateau.
Over the past 50-plus years, the
Central Government and the Tibetan local government have
conducted extensive surveys on Tibet’s biological
resources. They have worked out scientific plans and
programs for the protection of wild animals and plants. They
have also adopted a sequence of measures for effective
protection of the rare and endangered species. In accordance
with the relevant State laws and regulations, the Tibet
Autonomous Region has established forest law enforcement
organs and the Tibet Armed Police Forestry Contingent. They
have conducted the “Hohxil Action Number One”
and other special campaigns in the border areas of Qinghai,
Xinjiang and Tibet to protect the Tibetan antelope and other
rare animals. These campaigns have dealt a heavy blow to
poachers and curbed law-violation activities that have done
damage to wild animal resources. Meanwhile, the State has
invested millions of yuan each year in infrastructure
facilities for forest security and forest fire prevention in
Tibet. In 2002, the State set aside 3.66 million yuan from
its national debt revenue for a special project aimed at
cracking down on poachers of Tibetan antelopes. It has also
strengthened publicity on the protection of wild animals.
Now people in Tibet are highly conscious of the importance
of protecting wild animals, and the once rampant hunting of
Tibetan antelopes has been brought under control.
Over the past 50 years or more, not one
species in Tibet has suffered extinction. Biodiversity is
effectively maintained, and biological types are
continuously enriched. Red deer, generally considered by the
international animal research community to have vanished in
the 20th century, were discovered again in Tibet in the
1990s, and their numbers are increasing. As Tibet opens
wider to the outside world, non-native creatures such as
carp, crucian carp, eel and loach, high-productivity and
quality cattle, sheep, pigs, chicken, ducks, as well as
corn, watermelons and vegetables have been introduced from
the inland areas to Tibet, where they are thriving today.
Great achievements have been made in the
establishment of nature reserves. Establishing nature
reserves is an important method used by Tibet to strengthen
ecological improvement and environmental protection work and
implement the strategy of sustainable development. Since the
1980s, Tibet has established more than 70 nature reserves of
different types. Of these, three are on the national level
(four more national-level nature reserves are being planned)
and 15 are on the autonomous region (provincial) level. The
total area of the 18 nature reserves is 401,000 sq km,
accounting for 33.4% of the land area of Tibet and 30.8% of
the total area of China’s nature reserves. In
addition, prefectures and prefecture-level cities in Tibet
have established over 50 nature reserves of the
corresponding level. A rationally distributed nature
protection network of different types is basically in place.
In light of the general program and requirements of the
State, the People’s Government of the Tibet Autonomous
Region is carrying out the “Development Plan for
Nature Reserves in the Tibet Autonomous Region for
1996-2010.” It is expected that 28 new nature reserves
at or above the autonomous region level will be established
before 2010. By then, all types of nature reserves other
than sea and seashore ecosystem ones will be found in Tibet.
In order to restore the natural ecosystem,
human activities such as economic development are strictly
limited in the established nature reserves. As a result, the
ecological environment in most of the nature reserves has
become stable and the prospects are quite good. Breeding
grounds, habitats and important ecosystems for rare and
endangered species, important wetlands for migratory birds,
as well as the natural landscapes, geological sites and
biological sites of scientific importance are now well
protected. All the 125 wild animals, 39 wild plants and
typical geological features in Tibet that are on the State
protection list are well preserved in the established nature
reserves. The Tibet Autonomous Region has more than six
million ha of wetland, accounting for about 4.9% of
Tibet’s total land area and ranking first in China.
Its alpine wetlands are unique in the world. According to
monitoring by the relevant departments, the number of both
wild animals and plants in the nature reserves is obviously
increasing, and the total reserves of wild animal resources
have increased by upwards of 30%. Rare animals that had not
been seen for many years have returned to their habitats. In
the Changtang Nature Reserve, monitoring in the past few
years has revealed that the numbers of wild animals such as
Tibetan wild donkey, argali and antelope have increased to
differing degrees. The number of Tibetan antelopes has
reached 40,000 to 50,000 in the Nyima central reserve. After
a nature reserve for black-necked cranes was established on
the middle reaches of the Yarlungzangbo River, the number of
black-necked cranes wintering there has increased each year,
accounting for about 80% of the earth’s total number
of black-necked cranes.
III. Ecological
Improvement and Environmental Protection amid Economic
Development
The ecosystem in Tibet is
extremely fragile, and the ability to resist disturbance and
regenerate is weak. Once the ecosystem is damaged, it is
hard to restore it for a long period of time. For more than
50 years Tibet has adhered to the strategy of sustainable
development, ensuring the close combination and coordinated
development of ecological improvement, environmental
protection and economic construction. While the economy
develops rapidly and the people’s living standards are
constantly rising, the ecological environment is being
effectively protected. In accordance with the latest
monitoring findings, the environment of water and the
atmosphere in Tibet are basically unpolluted. The average
annual concentration of suspended particles in the
atmosphere of Tibet’s cities is between 193 and 268
per cu m. No major environmental pollution accident has
occurred in Tibet, and most of its major rivers and lakes
are in a primordial state.
Environmental protection and ecological
improvement are synchronized with agricultural production
and development. In Tibet, the natural conditions for
agriculture are poor, infrastructure is weak, grain
productivity is low and the capability to withstand natural
disasters is low. Therefore, it is necessary to strengthen
agricultural infrastructure construction, transform low- and
medium-yield fields and improve the level of the
agricultural ecosystem for agricultural production and
development. With this aim in mind, the government of the
Tibet Autonomous Region has endeavored to raise grain yield
by improving the eco-environment for agricultural
development. The government is helping farmers change their
traditional cultivation habits of letting land lie idle
after harvest — a centuries-old practice known as
“white fallow,” which is detrimental to water
and soil conservation. Rotation of grain and grass is
adopted to increase the fertility of the soil and its
ability to conserve water. While attention is paid to
farmland water conservancy construction, a forest shelter
network is being built to protect farmland from being eroded
by sandstorms. As a result of persistent efforts, the rate
of land usage in the major agricultural producers in central
Tibet has increased greatly, and the level of soil erosion
has declined markedly. Natural conditions like water and
heat, which are fundamental to the growth of farm produce,
have been improved. In 2000, surveys by experts found that
the comprehensive eco-environment appraisal index of this
area has gone up by 1.5 percentage points from 10 years ago.
The improvement of the ecological environment has steadily
increased agricultural productivity. By 2001, agriculture in
Tibet had had bumper harvests for 14 years in a row. The
total grain output had reached 982,500 tons, enough to make
Tibet basically self-sufficient.
The State has
invested a large sum of money on a series of comprehensive
agricultural development projects in Tibet. It is making
sure that while land areas are expanded, the ecological
environment is improved at the same time. In the major
construction projects, such as the comprehensive
agricultural development project on the middle reaches of
the “three rivers” with an investment of 1.2
billion yuan from the Central Government, environmental
protection and ecological improvement are made key parts of
the projects. Monitoring of the ecological environment in
comprehensive agricultural development in the “three
rivers” area in the past 10 years indicates that, due
to an organic combination of biological and engineering
measures, both the types and rate of land utilization and
the acreage of man-made vegetation in the area have
increased markedly. Desertification and soil erosion have
been effectively checked, and the comprehensive index of the
eco-environment quality has been raised by one to three
grades. Comprehensive agricultural development has not only
reaped significant economic benefits, but also resulted in
good social and ecological benefits.
Industrial projects are selected carefully,
and pollution prevention and control are strengthened.
Industry was not developed at all in Tibet until after the
region’s peaceful liberation. Even today, there are
few industrial enterprises in Tibet, and so industrial
pollution is not much of a problem. In order to reduce the
bad effects caused to the ecological environment by
industrial development, the government of the Tibet
Autonomous Region has adhered to the principle of placing
equal emphasis on both industrial development and
environmental protection. As industries are developed in the
region, Tibet has made every effort to ensure that while
they bring about economic profits they have social and
environmental benefits as well. No industrial project is to
be launched just because of its envisaged economic benefit
or just because it will fill a gap in the field. To
effectively combat pollution, the government has adopted a
series of pollution-prevention measures to ensure that the
development of modern industry does not damage the
ecological environment. First, industrial pollution is dealt
with through industrial restructuring, product-mix
adjustment and technological transformation. For instance,
the Lhasa Leather Factory has imported
environmental-protection facilities along with advanced
technologies and equipment from Germany. The Lhasa Brewery,
which used to be a big polluter, has spent more than four
million yuan on equipment to treat industrial sewage as part
of its technological transformation efforts. As a result,
its sewage discharge has met the specified standard. Second,
supervision and management of the environment has been
tightened. Rectification has been carried out in respect of
enterprises that fail to meet the requirements for pollutant
discharge. In accordance with the guiding principle of
“opening big enterprises and shutting down small
ones” for industrial restructuring, six vertical-kiln
cement production lines in Lhasa proper, which used to be
serious polluters, have been shut down. Enterprises causing
serious pollution are barred from production, and outdated
technologies and equipment prohibited by the State have been
winnowed out. Strengthening evaluation and management
of the impact of resources development and major
infrastructure construction projects on the ecological
environment. A policy is implemented ensuring that no new
construction, reconstruction and expansion projects shall be
authorized unless an evaluation of their impact on the
environment has been conducted. This policy and the system
of the “three simultaneouses” (pollution
prevention facilities are designed, built and commissioned
simultaneously with the main project) are strictly enforced.
More than 80% of medium-sized and large construction
projects have gone through evaluation of their impact on the
ecological environment. The Norbusa and Shangkasam chromite
mining projects include eco-environmental protection as a
key task in resources development. With respect to the
hydropower station at Yamzhoyumco Lake, which has attracted
the attention of the world, full consideration was given to
the protection of the ecological environment, starting from
the decision to build the station to its design and
construction. Since this hydropower station was put into
operation, electricity generation has not caused the water
level in the lake to drop, which would have harmed the
natural eco-environment of the lake. Much attention
has been paid to the comprehensive treatment of the
ecological environment in urban areas in order to improve
people’s living environment in areas with dense
population. The comprehensive management of the
ecological environment in cities and towns has always been
stressed in ecological improvement and environmental
protection work in Tibet. To guarantee the quality of the
atmospheric environment, Tibet is actively popularizing the
use of non-polluting energy sources in cities and towns, and
phasing out fuels such as faggot, ox dung, coal and oil
currently being commonly used by local residents. It
encourages people to adopt natural gas as fuel for daily
use. By 2001, the number of liquefied petroleum gas users in
Lhasa and Xigaze had increased to 44,600 households,
accounting for 83% of their combined total. At the same
time, Tibet is actively using clean energy sources like
water, geothermal, solar and wind energies. A pattern
featuring water energy as the main energy source
complemented by other types of energies has initially been
formed, and has been a great help to the protection of the
ecological environment. The amount of solar energy used in
Tibet each year is equivalent to that provided by 130,000
tons of standard coal. In Lhasa and Xigaze, 1,693.6 ha of
land are covered by trees or grass, and 47.48 ha are public
green areas. The rate of green coverage in established
districts is 23.5%. Construction of plumbing and treatment
of sewage have been pushed ahead in urban areas, and 679,460
m of water supply pipes and 392,770 m of sewage pipes have
been laid. The government has invested 51.2794 million yuan
in building Lhasa’s garbage disposal plants, and
garbage disposal facilities for other cities are being
actively planned. Devoting major efforts to the
development of tourism and other specialty industries that
are beneficial to the protection of the ecological
environment. Developing specialty industries with relatively
little impact on the ecological environment has always been
an important policy in accelerating the economic development
of Tibet. With its unique natural geographical and cultural
environments, Tibet enjoys a nature-endowed advantage in
developing tourism and other tertiary industries. In 1996,
the People’s Government of the Tibet Autonomous Region
adopted the “Decision on Speeding Up the Development
of Tourism,” and put tourism — one of the
Autonomous Region’s pillar industries — in a
prominent place and develop it vigorously. In 2001, Tibet
played host to 686,100 domestic and foreign tourists, its
earnings from tourism totaling 750 million yuan and its
earning of foreign exchange reaching 46.38 million US
dollars. Some 6,506 people are directly involved in the
tourist industry, while more than 30,000 people are
indirectly involved. The status of tourism in Tibet’s
economy is rising. Although tourism pollutes the environment
to only a very small extent, the local government has paid
much attention to problems arising from the damage to the
ecosystem and from environmental pollution in the
development of tourism. Tourism and environmental protection
departments are actively taking measures to collect,
classify and dispose of garbage left in scenic spots to
prevent pollution of the eco-environment. Garbage bins have
even been set up at the harsh Mt. Qomolangma mountaineering
headquarters. Garbage left by climbers and tourists is
collected, removed and disposed of periodically.
IV. Building an Ecology-Friendly Railway
Line — the Qinghai-Tibet Railway
There
was no highway in Tibet before its peaceful liberation.
Economic and social contacts in Tibet and its contacts with
the outside world depended solely on human power and draft
animals, as well as post roads. Now, a transportation
network consisting of 24,000 km of highways, a dozen air
routes and more than 1,000 km of pipelines has been
completed. Still, Tibet remains the only autonomous region
(province) in China inaccessible by rail. Transportation has
long been a bottleneck holding back the economic and social
development of Tibet and hindering the improvement of the
people’s living standards. Building the Qinghai-Tibet
Railway has been the long-cherished wish of people of all
ethnic groups in Tibet. It is not only essential for
strengthening links between Tibet and the hinterland,
accelerating the economic and social development of Tibet
and improving the local people’s material and cultural
well-being, but is also of great significance for enhancing
ethnic unity and common prosperity.
On June
29, 2001, with the approval of the Central Government,
construction of the section between Golmud and Lhasa began
as part of the second phase of the Qinghai-Tibet Railway
project. This railway line will be 1,142 km long, and will
involve an investment of 26.21 billion yuan. It will take
six years to complete. Making the Qinghai-Tibet Railway an
ecology-friendly railway line was the goal set at the time
the project was appraised.
During the initial
research period, an appraisal of the impact of the railway
line on the environment was carefully conducted. In the
initial period of the project, relevant departments chose
several aspects that would affect the ecological
environment, and conducted intensive research. On the basis
of this research and with arrangement by the Chinese
government, specialists from various fields carried out
in-depth on-the-spot investigations, and conducted a sound
scientific appraisal of the impact of the railway building
on Tibet’s ecology and environment in light of the
requirements of the environmental protection, water and soil
conservation, and wild animals protection laws, and those of
the “National Plan for Eco-environmental
Improvement,” and the “National Program for
Eco-environmental Protection.” They compiled a report
and some other documents, offering their appraisals of the
environmental impacts, together with proposals for
protection of the ecological environment. In light of the
requirements of the appraisal, a guideline for the
construction of the project was worked out, i.e.,
“giving priority to prevention and protection and
attaching equal importance to both development and
protection.” The result of the appraisal of the
ecological environment was used to guide the designing and
construction of the railway line and its environmental
management. Some 1.2 billion yuan will be spent on
environmental protection facilities for the Qinghai-Tibet
Railway, a record sum in this aspect for rail construction
in China.
At the design stage of this railway
line, protection of the ecological environment was the
deciding factor in the plan for the project. Protection of
the ecological environment has been an essential concern in
the design of the Qinghai-Tibet Railway. The routes were
selected so that they would keep away from the major
habitats of wild animals. The original design of the railway
would have it passing through the black-necked crane nature
reserve on the middle reaches of the Yarlungzangbo River.
After many discussions, the designers decided to select a
circuitous route via Yangbajain, to avoid disturbing the
birds. But if avoidance was impossible, such as the section
cutting through the Hohxil, Qumar and Soga nature reserves,
the planners would compare several designs, and put forward
protection measures to minimize disturbance to the nature
reserves. Based on the investigations and studies of the
habits and migration patterns of the wildlife along the
railway line, the planners established 25 passageways for
wild creatures at different sections of the line. In
designing bridges and tunnels, the designers gave full
consideration to the needs of wildlife crossing the railway
line. At many spots, special bridges were planned to provide
passageways for migrating wildlife so that the normal life
of these animals would be guaranteed as far as possible.
Hohxil is one of the habitats of the Tibetan antelope, which
faces the danger of extinction and is under the
State’s first-grade protection. In June and July each
year, they form groups and travel long distances to Zhoine
and Taiyang lakes to breed. The builders of the railway line
stopped work for four days, withdrew workers and equipment
from the construction site and removed the colored flags
that would alert and frighten the Tibetan antelopes. The
animals eventually passed through the construction site
without being disturbed. To prevent damage to grasslands and
wetlands, the planners designed many special bridges. The
total length of bridges built for this railway line in Tibet
alone would reach 13 km. When completed, the stations
along the Qinghai-Tibet Railway will use
environment-friendly energy sources such as electricity,
solar energy and wind energy for heating. Garbage at the
stations will be collected for batch treatment. Domestic
sewage, after being treated to meet the State’s
discharge standard, will be used, whenever possible, to
water green spaces. The passenger cars will be sealed.
Garbage on the trains will be collected in plastic bags
which will be handed over to stations along the plateau for
batch treatment. To suit the characteristics of the plateau,
the central station management mode will be adopted, with
seven central stations established along the line. Each of
these stations will be totally responsible for the
trains’ running and maintenance in an area within a
radius of 80 km. Wherever possible, remote automatic control
and mechanized maintenance will be adopted to reduce the
number of both the organizations and their staff on the
plateau, thereby giving maximum protection to the natural
eco-environment of the Qinghai-Tibet Plateau.
Reducing the adverse impact of the railway
construction on the ecological environment to the minimum.
To achieve this goal, all the construction units have signed
a responsibility pledge for eco-environmental protection
with the Qinghai-Tibet Railway Construction Planning Office.
The Office also requires all construction units to formulate
or improve rules and regulations for protecting the
ecological environment, and establish environmental
protection sections run by full-time or part-time
administrators. It is also imperative for the construction
units to take specific scientific measures to protect the
ecological environment; and their construction plans must
meet the requirements for environmental protection.
Competent governmental administration departments of land,
environmental protection and water conservancy and relevant
units responsible for design, supervision and construction
must work together to decide on the sites for taking and
discharging dirt and placing building materials such as sand
and stone. They should determine, according to the
availability of sunlight and hardness of ice, the
appropriate distance between those sites and the railway
roadbeds, as well as the traffic routes for workers and
vehicles. Construction and relevant activities should be
done within the designated areas to keep the permafrost
stable. The headwaters and wetlands along the railway line
are to be specially protected to avoid desertification in
the headwaters areas, shrinkage of wetlands, deterioration
of grasslands and water pollution that might be caused by
the construction. Attention is to be paid to the protection
and regeneration of ground vegetation. In places difficult
for plants to grow and on the construction sites and
transportation routes, the turf should be preserved and
replanted in other places section by section, to be moved
back to cover the slopes of the roadbeds and construction
sites, so as to minimize the loss of ground vegetation.
Where natural conditions are relatively good, grass seeds
suitable for plateau areas should be carefully selected and
planted with appropriate means of cultivation to restore as
much as possible the ground vegetation that existed before
the railway construction. Where the natural conditions are
good enough, turf to be cultivated by manpower should be
tried out, supported by the techniques of spray sowing and
plastic film mulching. In the Tuotuo River area, where the
Yangtze River originates, test-planting of grass on plateau
roadbeds has been successful in the first stage. The railway
builders will take all measures to meet the environmental
requirements of the railway construction. A key point
in building the Qinghai-Tibet Railway is to protect the
ecological environment along the railway line. All units
involved in the construction are making great efforts in
this respect. The China Railway No. 14 Engineering Bureau,
for instance, has 13 key technical problems now undergoing
scientific research, of which half concern environmental
protection. There are six supervisors in this bureau who are
in charge of eco-environmental protection on the railway
construction sites. They are responsible for ensuring that
the camp sites, work-site access roads and passageways,
quarries, and sites for supplying dirt and digging trenches
take up as little space as possible. They are also
responsible for supervising accommodation facilities to
ensure that the delicate plateau vegetation is properly
protected.
Taking effective measures to
minimize the pollution that the railway construction might
cause to the plateau’s ecological environment. To
achieve this goal, the construction units have tried to use
high-efficiency, low-noise and low-pollution equipment. They
have tried to adopt more mechanized ways of construction and
use as few administrators and workers as possible on the
work sites. Whenever possible, prefabricated concrete
components are carried to the construction sites and
assembled there. In order to avoid the pollution caused by
slurry around bridge-building sites, they use dry-boring by
rotary drills where possible. The Office requires that all
waste water from construction and camp sites be processed to
meet the corresponding sewage treatment standard before
discharge. Solid waste from construction sites and trash
from camp sites must be sorted out and recycled whenever
possible. Waste and trash that cannot be degraded should be
moved to appropriate places for batch treatment. Strengthening supervision and inspection of
environmental protection to meet the protection
requirements. An environmental protection supervision system
for a whole railway line was first adopted for the
Qinghai-Tibet Railway. The Office entrusted a third party to
supervise the environmental protection work all along the
line during the whole period of the railway construction. To
strengthen such supervision and inspection work, the State
Environmental Protection Administration and the Ministry of
Railways jointly issued the “Notification on
Strengthening the Supervision and Management of the
Eco-environment in the Building of the Qinghai-Tibet
Railway,” setting out specific requirements for the
environmental protection and supervision work during the
construction period. The State Environmental Protection
Administration, the Ministry of Railways and other
government departments concerned have repeatedly sent
inspection groups to supervise the implementation of these
environmental protection measures. Any violation of the
environmental protection regulations is severely punished. With the concerted efforts of all concerned it is
justifiable to believe that the Qinghai-Tibet Railway, as a
plateau railway up to the environmental protection standard,
will truly benefit the people of all ethnic groups in Tibet. V. The Strategic Choice for Sustainable Development For the past 50 years or so, benefiting from the
concern of the Central Government and support from the whole
nation, people of all ethnic groups in Tibet have pulled
their full weight to give an earth-shaking new look to
Tibet, and have made achievements in ecological improvement
and environmental protection that have attracted attention
worldwide. Tibetan people today live and work in peace not
only with a booming economy and developing society, but also
with their landscape kept beautiful, their rivers kept
clean, their animal species kept diversified, and their
vegetation kept lush. Tibet has truly become a
“Shangri-la.” Rapidly shaking off its
traditional backwardness and quickening its steps toward
modernization are the natural requirements for the progress
and development of Tibetan society and the fervent wish of
all the ethnic groups in Tibet. Located on the Qinghai-Tibet
Plateau, Tibet has a peculiar geographical environment and a
fragile ecosystem. Therefore, it is an important part of
Tibet’s progress to modernization and a strategic
choice for sustainable development that Tibet should protect
the regenerative capacity of its natural resources, improve
the quality of its ecological environment, preserve the
integrity and self-adjustment ability of its natural
ecosystem, and ensure the safety of the ecosystem and the
harmonious unity and coordinated development of
Tibet’s economy, society and ecosystem. Ecological improvement and environmental protection
in Tibet cannot be achieved if development steps falter, but
nor should we attain short-term economic development at the
cost of the ecological environment. We can only follow the
law of social development, attach equal importance to both
economic development and eco-environmental protection,
giving attention to protection in the process of development
and seeking development in the process of protection, and
implement the strategy of sustainable development.
Ecological improvement and environmental protection should
be done in an active, thrusting and dynamic manner, and not
in a passive, conservative and closed-door way. We cannot
refuse any interaction between man and natural
eco-environment on the excuse of preserving the fragile
primitive natural state, because this will hamper the
economic and social development and the improvement of
people’s living standard in Tibet.
The
relationship between the exploration and utilization of
natural resources and eco-environmental protection must be
handled properly in the course of the modernization of
Tibet, so as to promote changes in the mode of economic
growth. It is clear from past experience in Tibet that the
exploration and utilization of natural resources must follow
the laws of nature, taking both long-term and overall
interests into consideration, so as to avoid being too eager
for quick success and instant benefits to the extent of
over-burdening the ecological environment. A scientific
attitude and methodology must be adopted in exploring
natural resources and protecting the ecological environment.
Natural resources that are not to be explored and used
should be strictly protected, while the exploration and
utilization of needed resources should be done
scientifically with a definite goal, to prevent any unwanted
impact on the ecological functions. Only in this way can the
natural resources in Tibet be utilized rationally and
scientifically, and can economic development and
eco-environmental improvement be achieved simultaneously. Tibet’s ecological improvement and
environmental protection, just as its economic and social
development, have a vital bearing not only on the
fundamental interests of the people of all ethnic groups in
Tibet but also on the common interests of the whole nation.
People of all ethnic groups in Tibet are the major
motivators and direct participants in the ecological
improvement and environmental protection work in Tibet. They
are also the main beneficiaries of a well-preserved
ecological environment. Carrying forward such work will
benefit both the State and the people for generations to
come. Starting from the fundamental interests of the Tibetan
people and the fundamental demand of the people of all
ethnic groups across China for common prosperity, over the
past five decades and more the Chinese Central Government
and the local government of Tibet, in a spirit of being
highly responsible for posterity and the world as a whole,
have made tremendous efforts to promote and develop the
ecological improvement and environmental protection work in
Tibet, and have made achievements that have captured
worldwide attention. The Dalai clique and the
international anti-China forces shut their eyes to the
progress in the ecological improvement and environmental
protection work in Tibet. They have spread rumors all over
the world that the Chinese government is “destroying
Tibet’s ecological environment,”
“plundering Tibet’s natural resources” and
“depriving the Tibetan people of their right to
subsistence,” and so on and so forth, in order to
mislead world public opinion and deface the image of China.
Camouflaging themselves with pretensions of concern about
eco-environmental protection in Tibet, they want really
nothing but to hamper the social progress and modernization
of Tibet and to prepare public opinion for their political
aim of restoring the backward feudal serfdom in Tibet and
splitting the Chinese nation.
It is true that
there are still many problems in Tibet’s ecological
improvement and environmental protection efforts. As the
whole global ecosystem is deteriorating, the fragile ecology
in Tibet is particularly affected. Mud-rock flows,
landslides, soil erosion, snowstorms and other natural
calamities occur frequently in Tibet and desertification is
threatening the region’s eco-environment, compounded
by man-made damage to the ecological environment as
Tibet’s economy develops. All these things have
attracted much attention from the Central Government and the
local government of Tibet. In order to ensure the permanent
stability of the ecological environment and natural
resources and to guard against possible new threats to them,
the Tibetan local government, supported by the Central
Government, has set up and put into practice since 2001 a
mammoth plan for ecological improvement and environmental
protection. From now until the mid-21st century, more than
22 billion yuan will be invested in over 160
eco-environmental protection projects aimed at steadily
improving the ecosystem in Tibet. There is no doubt that the
people in Tibet will create an even more beautiful
environment and an even better life for themselves in the
course of their future development. (China.org.cn
