摘　　要：美国的通用土壤流失方程USLE是当今世界上应用最为广泛的水蚀模型。 2 0世纪 70年代中期以来 ,我国在引进、消化、应用USLE方面取得了突破性的进展 ,统一了方程中R、K、S、L、C、P的算法 ,将六大因子的计算完全基于GIS和RS ,提高了监测预报的精度和速度 ,已成功地在国内一些地区得到应用。Universal Soil Loss Equation (USLE) of the United States is the most popular water erosion model applied in the world. Since the mid 1970s, China has achieved a break through progress on the aspects of introducing, digesting and applying. It has integrated the calculation method of R, K, S, L, C and P of the equation, put the operation of the six main factors into GIS and RS and increased both precision and speed of monitoring and forecasting. It has been successfully applied in some regions of China. The paper introduces the development process of USLE and the application and development in China.
