In this paper, based on 16-day 250 m MODIS product suits, using residual trend method, the effects of Restoring Grazing to Grassland Project in Maqu grassland was evaluated. Firstly, some regression models between NDVI in different stage and synchronous meteorological data were constructed. Then using above models we can predict NDVI value without the project and analyze the residual trend of actual...
