摘　　要：为了及时、准确地掌握水土流失现状,了解水土流失变化规律,为区域水土流失防治确定科学的思路和目标,基于通用土壤流失方程（USLE）,应用RS和GIS技术对淮南矿区水土流失进行动态监测与分析。结果表明,1986~2012年,淮南矿区水土流失中度侵蚀和轻度侵蚀区面积比例减少,微度侵蚀区比例增加,矿区水土流失状况总体上趋向变好的态势。研究结果有助于指导淮南矿区水土流失防治及其生态系统的恢复与重建。In order to timely and accurately grasp water and soil erosion situation,understand the variation law,provide scientific thought and objective of regional water and soil erosion control,based on USLE,RS and GIS technology was applied to monitor and analyze water and soil erosion in Huainan mining area. The results showed that during 1986- 2012,proportion of moderate erosion and mild erosion area decrease,micro erosion area proportion increase. The results are helpful to guide the prevention and control of soil erosion in Huainan mining area and the restoration and reconstruction of ecological system.
