WEPP(Water Soil Loss Equation)作为新一代水蚀预报模型,是指导水土保持措施优化配置、水土资源保护与持续利用的有效工具。近年来,遥感和GIS技术为WEPP快速获取所需资料、处理数据、图像编辑和输出等提供可靠的技术支撑;同时,区域化、尺度概念的引入,为WEPP应用于大尺度提供技术保障。为借鉴WEPP模型的优点,促进我国水蚀预报模型的发展,对WEPP模型的最新发展进行了详尽的介绍,并对WEPP应用到我国时可能存在的问题进行了初步分析。; As a new generation prediction technology,Water Erosion Prediction Project(WEPP) is a guide to conservation planning and a tool for quantitative researches of soil erosion.In recent years,Geographic Information Systems(GIS) and Remote Sensing technologies have been introduced for generating,preprocessing and visual display of parameters in WEPP model.Meanwhile,the introduction of regionalization concept makes WEPP application in lager areas.This paper concentrated on the latest development of WEPP and brief...
