On the basis of the characteristics of grassland resources and current conditions of grasslands of Northern Tibet Plateau, the limit factores to vegetation restoration are identified, which include grassland degradation caused by both natural and artificial factors. The main ways to implement correct measures in vegetation restoration should include the ways of making rational use of natural resources, soil cultivation, founding forage production bases in other districts and strengthening research work.
