Change of ecological environment in Shenfu mining area of China based on gis and RS

The ecological environment in Shenfu mining area of China is fragile. Coal mining has impacted great influence on the ecological environment of mining area. To analyze the damage condition of ecological system and rapidly recover the damaged ecosystem plays an important role in regional sustainable development. Based on the remote sensing data of year 1989, 2002 and 2006, the index of NDVI, vegetation coverage, desertification and land use in the studied area were studied and analyzed. The research results showed that: The vegetation coverage was becoming better on the whole; however, in the mining area of large coal mines, the degree of vegetation coverage was still very low; the potential desertification area increased gradually, from 81661.02hm2 to 149200.74hm2; the severe desertification area reduced gradually. The research results provided a base for mine land reclamation and ecological restoration, which can play a positive role in promoting the construction of ecological environment in western area of China.
