Based on Remote Sensing (RS) and Geological Information System (GIS) technology, the paper analyses of Jinsha River basin with large scale and long time series, by the linear regression analysis, Mann-Kendall tendency analysis and multiple regression analysis. Data of Vegetative distribution and its changing tendency during 21 years (from 1981 to 2001) are acquired. The analysis result shows that vegetative cover in Jinsha River basin is in the rise.
