| 摘 要： | 土壤侵蚀模型是定量评价水土资源发展动态、指导综合治理规划、评价治理方案和措施的技术工具。根据建模的手段和方法，土壤侵蚀量预报模型有经验模型和物理成因模型两大类。根据建模对象的不同，土壤侵蚀模型又有坡面土壤侵蚀模型和流域土壤侵蚀模型之分。主要从这4个方面入手，介绍了国内外土壤侵蚀量预报模型研究的主要成就，指出了现有模型的不足。在总结前人工作的基础上，提出了我国土壤侵蚀模型今后的发展方向。

| Abstract: | The soil erosion model can be used to evaluate the dynamic development of the water and soil resources and develop plans for controlling soil erosion. The model can also be applied to assess the soil loss control practices. According to the purpose of the model and the way that the model is developed, the soil erosion model can be divided into two categories: empirical model and physically-based model. When the scale of model application is considered, soil erosion model can be classified into upland model and watershed model. The purpose of this paper is to review research history leading to development of the soil erosion model, present the limitation of the existing soil erosion models and give a direction of developing soil erosion model in China. |
