Abstract In order to explore the relationship between climate variation and vegetation change in Anning River Basin in the period from 2001 to 2008, the authors chose MODIS NDVI, precipitation data and temperature data as study materials and conducted regression analysis and other methods to obtain spatial-temporal change patterns of precipitation, temperature and NDVI in Anning River Basin; meanwhile, the response mechanism of vegetation change to climatic variations in Anning River Basin was investigated. The results show that NDVI is positively correlated with temperature and precipitation, and the precipitation and temperature affect the change of vegetation directly, but the influence of precipitation is more significant than that of temperature. In addition, there exists the feature of time-lag between vegetation change and climate variation.
