摘　　要：土壤侵蚀是世界范围内最重要的土地退化问题之一。正确预测人工开采引发的人为加速土壤侵蚀,可为生态脆弱煤矿区的生态恢复和重建提供依据。文章采用遥感技术,结合实地调绘、统计分析、历史类比等方法,针对乌东矿区采煤沉陷对土壤侵蚀的影响进行了预测研究。结果表明:地表沉陷从一定程度上加剧了矿区内土壤侵蚀的强度,其中强度侵蚀和中度侵蚀面积增加迅速,轻度侵蚀面积显著减少,无侵蚀和微度侵蚀面积也存在一定程度的减少。Soil erosion is the most important land degradation problems. Prediction of artificial exploitation of a manmade accelerated soil erosion can provide the basis for the ecological restoration and reconstruction in the ecological fragile coal mine area. In this paper, by using remote sensing technology, combined with field survey, statistics analysis, historical analogy method,the research forecasts the coal mining subsidence impacts on soil erosion in Wudong mining area. The results show that the surface subsidence to some extent intensified the soil erosion intensity in mining area, the intensive erosion areas and moderate erosion areas had kept going up rapidly, the light erosion areas decreased significantly,there was a certain degree of reduction in no erosion and slight erosion areas.
