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).
