these wetlands leads to the failure of inherent
storage capacity in swamps, which undoubtedly is a
major disadvantage for three-river source areas. To a
large extent, it impeded the grassland development
of three river sources. Meanwhile, due to short
supply and lack of nutrients, vegetation has been
close to death. Serious wetland degradation has been
a huge threat to three-river source areas, forcing
humans to take measures to stop its development.
2.3 Pest Invasion
For grasslands of three river sources, its hostile
ecological environment has decreased resistance
ability against outside. Increasing amount of weeds
caused rapid reduction in areas of utilizable grass.
Meanwhile, the invasion of natural enemy rodents
also led to the sharp decline of grasslands due to
their consumption and destruction. Caterpillars, in
addition, are responsible for large bare lands
presented in several areas. Pest invasion
undoubtedly worsens the already weak grassland
situation of three river sources, which accelerates
sharp reduction of grasslands and destruction of
ecological environment.
2.4 Degeneration of Ecological System
Various rare animals lived on grasslands have
positive significance in sustainable grassland
multiply of three river sources. However, due to
hunting of animals by humans, the amount of rare
animals sharply declines, including white-lipped
deer, blue sheep and Tibetan gazelles. This has
brought a critical strike to sustainable grassland
development of three river sources.
Three-river source areas are faced with
phenomena such as biological system degeneration,
pest invasion, wetland degradation and soil erosion.
Therefore, ecological migration is necessary for
grasslands of three river sources in order to promote
its sustainable development of ecological system and
recovery of ecological environment.
3 PREDICAMENT OF
GRASSLAND ECOLOGICAL
MIGRATION OF THREE
RIVER SOURCES
With increasingly serious destruction of ecological
system and environment, well multiply of grasslands
has become an important issue in three-river source
areas at present. Therefore, it is necessary to carry
out ecological migration project. In the process,
however, several predicaments are required to be
broken through for smooth project implementation.
Currently, the unsolved issues in ecological
migration mainly lines in the following aspects:
3.1 Mass Misconception
Due to the lack of the cognition to ecological
migration and environmental protection, resistance
and reactionary aspect emerge in implementation
process, which is undoubtedly a predicament of
grassland ecological migration in three-river source
areas. The concept of ecological environmental
protection lacks sufficient publicity in most areas of
China. Many people are just limited in knowing or
verbal recognition of it. When there are conflicts
between ecological environment and personal
interests, opposite voice of the project becomes
louder. Therefore, for the large long-term migration
project, only correct mass conception can
fundamentally solve the issue and guarantee the
project implementation.
3.2 Mass with Low Quality
Grassland ecological migration project of three river
sources has to guarantee the recovery of ecological
environment and the basic living of immigrants as
well as the development of immigration areas.
However, for people living in three-river source
areas, most of them are herdsmen with limited
education currently. Many families do not support
children to receive education, and some even take
measures to evade education. Failure of education
and teaching work has led to relatively low quality
and limited skills of people in the areas. Meanwhile,
without other labor skills, re-employment of local
people is unable to be effectively arranged. Narrow
channels for employment have made negative
effects on the development of local politics,
economy and culture.
3.3 Cultural Difference
As localities of minorities since ancient times, three-
river source areas have created own unique culture
that is different from other areas. The cultural
difference is quite unfavourable to local migration
work and has become an important issue in
migration process. Grassland ecological migration
project of three river sources includes the transfer of
people as well as culture (e.g. material culture,
