| Abstract: |
| This paper analyzed the land use change in Yarkant River Basin during recent 20 years using Landsat-TM and CBERS images from 1990, 2000, and 2010 combined with GIS and the ecological environment index calculation methods. The results showed that during the years from 1990—2010, the species richness index, vegetation coverage index and land degradation index were decreased by 4.53%, 4.00% and 3.56%, respectively, while the water density index was increased by 3.71%. Additionally, the eco-environment condition indexes of Yarkant River Basin were 34.94, 34.77 and 34.32 in 1990,2000 and 2010, reaching a dissatisfactory level. The ecological environment became degraded by influences from both the natural and human activities. |
