The spatial and temporal patterns of NDVI are the same, while spatial analysis shows that the NDV1 is influenced by the vegetation types growing in the study regions, and NDV1 presents an increasing trend during the study period in the whole basin. The climate indicators play an important role in the changes of vegetation cover in the river basin. In the two Indicators, temperature has a significant effect on the NDVI values than precipitation in the whole basin.
