摘　　要：随着对土壤水蚀形成过程及其模拟研究的深入,侵蚀预报模型已由经验模型、物理过程模型向分布式模型发展。重点介绍了几种国外具有代表性的分布式水蚀模型,并对国内土壤水蚀分布式模型的研究现状进行了评价,指出了目前我国模型研究中存在的问题,以及建立我国土壤侵蚀预报模型所必须开展的研究工作和需要解决的科学问题。Along with the thorough study on formation process of water erosion of soil and its simulation,erosion forecasting model has been developed from empirical model and physical process model to disaggregation model.The paper introduces some typical water erosion disaggregation models in foreign countries,evaluates the present status of study on water erosion disaggregation model conducted in China and points out the existing problems in model study;the necessary work should be developed and scientific issues to be solved in establishing soil erosion forecasting model in China.
