摘　　要：在收集、研究前人研究成果的基础上,应用土壤水蚀模型和流域泥沙输移比初步建立了泥石流坡面侵蚀物源量计算模型,同时列举了降雨侵蚀力因子、土壤可蚀性因子、地形因子及植被覆盖因子等水蚀因子的标准算法和经验算法,具有较强的理论依据,对泥石流坡面侵蚀物源量计算具有借鉴意义。A model for calculating the amount of erosion material on the slope of debris flow is established by means of soil water erosion model and sediment delivery ratio on the basis of previous achievements. At the same time, standard algorithm and empirical algorithm for sediment delivery ratio and water erosion factors such as rainfall erosive power factor, soil erodibility factor, terrain factor and vegetation cover factor are enumerated.
