Abstract:WucaiWan open coalmine in the East Junggar Basin in XinJiang was selected as the research region, the disturbance of the WucaiWan open-pit coal mining on vegetation was analyzed using vegetation index and the vegetation fraction based on Landsat TM satellite remote sensing data from 2006 to 2011. First, the damaged speed and area change of different levels of vegetation during coal mining was analyzed using the characteristics and transfer matrix of the desert vegetation fraction in open coalmine area. Second, the changing characteristics of the vegetation fraction with time were studied and the damaged area and the extent of the vegetation was quantitatively analyzed using temporal and spatial variation of the vegetation fraction. The results indicate that, from 2006 to 2011, the damaged vegetation extent showed an increasing trend year by year due to coal mining in the study region, the vegetation fraction decreased 1.2 % per year, and the lower the level of vegetation is, the faster the speed of vegetation breakage. In the study region, the area influenced by coal dust was accounted for 44.69% of the total area. The average distance influenced by the fine coal ash was about 3.2km, and the larger the scale of coalmine is, the further the influence. In the mining and dumping areas, vegetation-covered area was small accounted for 12.15%, but the vegetation fraction volatility changed in the range of 0.05~0.15, the vegetation was damaged seriously.
