| 摘 要： | 受流域内物质成分、气候条件和复杂侵蚀营力的影响，蒋家沟流域坡面侵蚀现象甚为严重。根据流域内坡面物质成分、气候、降雨等方面分析了发生坡面严重侵蚀的原因；并进行了大量的人工降雨侵蚀实验，分析降雨坡面产流产沙过程和特征。实验结果表明径流随降雨时间和降雨量的增加呈跳跃和波动性增加，泥沙含量随降雨时间增加而逐渐减小。

| Abstract: | The slope in Jiangjiagou Valley suffered from serious erosion due to the substance components, climate and the complicated erosion power. This paper expatiates the serious erosion on slope surface from the substance components, climate and rainfall.It also analyses the erosion principle and process with experiment of erosion inspired by artificial rainfall.The results of the experiments indicate that the runoff increases hopingly and fluctuatingly along with rainfall, while sediment content decreases when the rainfall increases. |

| Keywords: | erosion substance components artificial rainfall sediment yield and runoff |
