This paper expounds that the territory in Tibet Autonomous Region is very vast, but some basic natural resources such as arable land and grassland are not as rich as people usually think.With the population increases, especially in rural areas, Tibet is facing the problem of over-exploiting and overloading some natural resources.This issue is more severe in the prairies of Tibet.Therefore, the development of stockbreeding is facing serious challenges.The authors present some suggestions to resolve the problems from various perspectives.
