Base on investigation of soil and water loss in Baipenzhu reservoir catchment area, experimental research on rainfall-runoff-sediment yield of typical erosionlandform and vegetation was carried out.
Based on the composition of landform of each country, and an assuming of that the distribution of highway is similar, the erosion parameter and cutting slope erosion are analyzed.
Ravine density, which is an important factor indicating the extent of the fragmentation of the Earth surface, plays a significant role in the research of soil erosion and landform evolution, etc.
