摘　　要：土壤侵蚀预报信息系统的建立是动态分析处理土壤侵蚀信息,适时定量预报土壤侵蚀,进行水土保持规划和评价的重要技术基础。系统介绍了中国土壤水蚀预报信息系统的研制目标、系统组织结构和功能,以及系统的实际应用评价。The soil erosion prediction information system is very important for analyzing soil erosion information dynamically, forecasting soil erosion quantitatively and making soil and water conservation program. Chinese soil loss equation information system was developed with the support of the GIS(Geography Information System),which could manage all the data needed by the CSLE(Chinese soil loss equation),utilize (CSLE) to quantitatively evaluate the factors causing the soil erosion and estimate the potential soil loss. This paper introduced the target,structure, functuin and applied assessment of the system. 
