摘　　要：降水特征、地形地貌和植被覆盖程度是影响水土流失量大小的主要因素。降雨强度越大 ,坡越长越陡 ,水土流失量越大 ;植被覆盖度越高 ,水土流失量越小。因此 ,改变矸石山局部小地形、缩短坡长、快速恢复植被、提高土壤入渗是减少水土流失的有效途径。Precipitation features, landforms and the covering level of vegetations are the main cause affecting the quantity of water and soil loss. The bigger is the strength of the rain ,the longer and steeper is the slope ,the bigger is the quantity of water and soil loss. However, the higher is the covering level of vegetations, the smaller is the quantity of water and soil loss. Therefore, altering the small landform in waste rock hill partly, shorting the length of slope, recovering vegetations quickly, raising soil percolation are effective ways for decreasing water and soil loss.
