The NDVI trend and distribution of alpine grassland at plateau scale were studied. They were analyzed in relation to permafrost, soil moisture and LST-NDVI. Permafrost and soil moisture were important for grassland distribution and change. The LST-NDVI relationship only explained < 50% variation of vegetation changing trend. Other factors may overwhelm hydro-thermal conditions in affecting vegetation growth.
