摘　　要：流域侵蚀产沙模型是国际土壤侵蚀研究的重点领域之一,国内以往进行了较多研究,建立了许多模型。正确分析和评价这些模型对于合理地使用它们进行流域侵蚀产沙预报和水土保持规划等工作具有重要意义。从研究方法、模型结构、模型中各参数的确定等方面对我国主要流域侵蚀产沙经验模型和具有一定成因的模型进行了分析,并在此基础上对各模型进行了评价。A model of soil erosion and sediment yield in catchment is one of main research areas of soil erosion in the world. Many models of soil erosion and sediment yield in catchment were developed in China. Reasonable application of these models to the prediction of soil erosion and sediment yield, and soil conservation decision in catchment is very important.We introduced research methods, structures, parameter descriptions of main empirical models and physically-based models of soil erosion and sediment yield in catchment in China, and made an analysis of characteristics of these models.
