摘　　要：[目的]为了对人工草地不同植被度在暴雨条件下的产流产沙过程进行研究。[方法]采用野外人工模拟降雨试验。[结果]不同植被度对产流产沙过程均有明显的削减作用,其作用随植被度的增加而增加,呈正相关。[结论]该研究为进一步研究人工草地覆盖防止水土流失的机理研究拓展思路,为更有效防止水土流失及制定水土保持措施具有重要意义。[Objective] The research aimed to study the runoff and sediment yield process of artificial pasture of different vegetation in the heavy rain.[Method] The field artificial rainfall simulation experiment was carried out.[Result] The de.grees of vegetation had obvious reduction effect on runoff and sediment yield process.The reduction effect increased with the increase of the vegetation degrees,and had positive correlation.[Conclusion] The research developed the idea of further study the mechanism of artificial pasture coverage to prevent soil erosion.It had great significance to effective prevention of soil erosion and the conservation measures of water and soil.
