南方花岗岩地区坡面侵蚀临界坡度探讨

Study on Critical Erosion Gradient in Granite Region in Southern China

从坡面流拖曳力、流速、能量及挟沙力４ 个方面，分析了南方花岗岩地区坡面侵蚀临界坡度。

From the following four aspects: drag forces, velocity, energy and sediment carrying capability of slope surface flow, the threshold gradient of slope surface erosion in the granite area in the south of china is discussed, and it is obtained the critical slope gradient is from 35 to 43 degree.
