摘　　要：西藏日喀则是典型的生态环境脆弱区,针对部分矿山闭坑后矿山环境恢复治理的效果评价分析,主要采用遥感与GIS相结合的技术方法,以恢复治理区域为研究对象,通过不同期次遥感图像对比,分析矿山环境恢复治理的效果。发现总体上,矿山环境恢复治理取得了良好的效果,但个别区域开展矿山环境恢复治理工作后破坏了更多的草场,并且在西藏的特殊自然条件下还需要相当长的时间才能恢复草场,因此,在日喀则等生态脆弱区域需慎重选择土地平整的方式开展矿山环境恢复治理工作,建议土地平整后开展植草灌溉等后续工作,以尽快恢复草场,实现矿山环境恢复治理的目的。Shigatse of Tibet is a typical fragile area of ecological environment. Aimed at the mine environment rehabilitation for some mines after closing pit, the technical method combining remote sensing with GIS was mainly adopted. Taking the rehabilitation area as the research object, the effect of the restoration and treatment of the mine environment was analyzed through the contrast of different periods of remote sensing images. It was found that a good effect was generally obtained in the mine environment rehabilitation. However, in individual areas, mine environment rehabilitation damaged more grassland, and it would take quite a long time to recover grassland in Tibet under its special natural conditions. Therefore, the methods of land levelling should be carefully chosen to carry out the mine environment rehabilitation, especially in ecological fragile areas such as Shigatse. It was suggested that planting irrigation work should be put forward after land levelling, so as to recover the grassland as soon as possible, and to achieve the purpose of mine environment rehabilitation.
