The results indicate that the main erosion type is sheet erosion at the beginning of the rainfalls, and serious erosion happens after rill erosion appeared.
并且各污染物浓度均随降雨历时呈减少趋势，后趋于平缓，可采用弃流部分初期雨水后进行收集。
There was a decreasing trend in each pollutant concentration with rainfall duration and finally tends to flat. So we collect the rainwater after abandoning part of the initial flow of rainwater.
利用模拟降雨装置，研究了演替恢复初期不同植被覆盖以及不同处理下坡面降雨的产流过程和入渗率。
