摘　　要：近年来 ,我国在土壤侵蚀产沙模型方面进行了大量研究 ,建立大量的坡面、流域及区域侵蚀产沙模型。由于我国人多地少、地貌条件复杂多样 ,使得我国的侵蚀产沙有不同于欧美的特点 ,因此我国的侵蚀产沙模型研究有明显不同于国外土壤侵蚀模型的特点。本文对我国近年来主要的土壤侵蚀经验性模型、理论性模型进行了评述 ,并讨论了新理论、新技术以及国外一些土壤侵蚀产沙模型在我国土壤侵蚀模型研究中的应用 ;There are a lot of studies on soil erosion models in China in the recent years, and many hillslope models, watershed models and regional models have been built up. Since our current situations are too many people with limited land, as well as with complex and varied physiognomies in China, which make the characteristics of soil erosion different with European and America, so there are great distinctions between the characteristics of soil erosion models in China and the models of overseas. The paper reviewed the empirical soil erosion models and theoretic models, and discussed the applications of new theoreties, new techniques and some international erosion models. The paper pointed out future tends of the studies on soil erosion models.
