摘要
从降雨径流污染特点、径流过程、土壤侵蚀过程和泥沙传输过程，说明水土流失是一种严重的降雨径流污染形式，分析讨论了水土保持措施对降雨污染控制的难度，提出了水土保持措施设计的３条原则。
The results from characteristics of precipitation runoff, the process of runoff and soil erosion showed that soil and water loss is a serious form of rainfall runoff pollution, analysed and discussed the control difficulty in soil and water conservation measures, and put forward to design three principles of the soil and water conservation measures.
