摘　　要：通用土壤流失方程(USLE)在我国应用,重要的是要对各相关因子值进行科学的确定。结合遥感与地理信息系统(GIS)技术,可以实现以USLE为平台的区域土壤流失遥感监测。本研究介绍了USLE中因子的GIS生成以及土壤流失量的GIS生成过程,其研究成果可作为水行政部门决策与执法的依据,也可作为研究区域基础地理信息资料进行储存备份与延伸应用。The key of application of Universal Soil Loss Equation (USLE) in China is to scientifically decide each correlation factor value. It can realize remote sensing monitoring of regional soil loss by taking USLE as a platform through using the technology of remote sensing and GIS. The study introduces the processes of GIS generation of factors in USLE and GIS generation of the amount of soil loss. The achievements can be used as basis for decision making and law enforcement of water administrations and also can be used as regional basic geographic information data for storage, backup and extension.
