Abstract

The Through the simulating rainfall experiment, a contrast study on slope runoff and sediment yield characteristics of loess and purple soil under the same experimental conditions was conducted. The result shows that the loess slope develops the infiltration excess runoff and deeper erosion gullies, whereas the purple soil favors the saturation excess runoff with undeveloped or weakly developed slope channels. Furthermore, the slope erosion of the loess was much greater than that of the purple soil under the same conditions. When soil conservation measurements are made, appropriate methods should be taken according to the soil characteristics in order to achieve ideal effects..
