Summary: The Qinghai-Tibet Plateau is the highest geomorphic units on the earth with its elevations averaging over 4000 meters above sea level. Alpine grasslands on the plateau quickly and significantly respond to global climate change. With the obvious trend of climate warming, the process of land-atmosphere interaction has experienced complex changes in this fragile ecosystem. This project analyzes the growth trends of alpine grasslands using MODIS time series images at plateau scale, combines the measurements from meteorological sites, and extracts the temporal dynamics of alpine grasslands in different climatic zones and permafrost regions. These spatially explicit data layers are important for predicting the long-term ecological evolution of alpine grasslands on the plateau.
