土壤侵蚀模型是定量评价土壤侵蚀影响,进行土地利 用和水土保持规划的科学工具。总结了长江流域土壤侵蚀模型的主要成果，对长江流域国外 物理模型的应用、USLE模型的应用、经验性模型、物理过程性模型作了详细介绍，以期为今 后长江流域的土壤侵蚀模型研究提供一定的参考意见。

The soil erosion model is an important scientific too l for quantitatively evaluating the effect of soil erosion, conducting the program of land use and soil and water conservation. This paper summarizes main achievements of soil erosion models in Yangtze River basin, including the application of foreign physical models, USLE model extending, regression analysis models and models in watershed based on the mechanism of erosion mechanics , which are expected to offer some referenced ideas for the research of soil erosion models in Yangtze River basin in future. Most of empirical models are used in this district, and physical process models are in the phase of beginning, and however, practicability and popularization of foreign models application are awaited for strengthening. Soil erosion models in Yangtze River basin should be focused on their practical, deep, and multiple studies.
