总结了水力侵蚀预测模型GeoWEPP的发展历程、技术框架、适用性和局限性，从DEM数据、土地利用/覆被变化、管理因子和土壤要素等4个角度详细论述了GeoWEPP模型的研究进展，针对模型的优势及存在的问题，结合当前水文和侵蚀模型研究形势，对GeoWEPP模型未来发展的趋势与走向作了展望，指出该模型在DEM精度阈值的确定、空间尺度的转换、人类活动集中区的应用、与生态过程的结合以及WEPP与GIS集成开发5个方面有较大的拓展空间。%This paper summarized geo-spatial interface for water erosion prediction project ( GeoWEPP) model’ s development process, technical framework, applicability and limitations, and then respectively described current research development of GeoWEPP from the standpoints of dynamic effect model ( DEM) data, land use/cover change, management factors and soil factors. For the advantages and disadvantages combining with the research status of water erosion prediction model, this paper proposed development directions of the model and pointed out possibilities of development about GeoWEPP in five aspects:definition of the accuracy of DEM, transform of spatial scale, application in human activities center, combination with ecological process, and integrated development of WEPP and geographic information system ( GIS) .
