摘要

现代空间技术和基于GIS的土壤侵蚀定量评价预报技术，使区域水土流失快速调查成为可能。建立水土流失基础数据库，利用遥感技术快速调查和定期更新评价因子，开发空间型土壤流失评价模型系统，在GIS环境下进行土壤侵蚀的评价与统计分析，是土壤侵蚀快速调查的基本方法。对土壤侵蚀分类分区系统、土壤侵蚀评价因子选择、区域土壤侵蚀基础数据库建立、中国水土流失评价模型系统等是区域水土流失快速调查中的几个重要问题。

Abstract

The topic of rapid survey of regional soil erosion has been identified based on the analysis of sciences of soil erosion

spatial information technologies and the demand of soil conservation. The necessary and possibility of the survey have been analyzed focussing on the processes

the spatial characters of regional soil erosion and the theory and techniques of spatial informatics. Some important issues

including the classification and regionalization

the parameterization of the evaluation

the modelling of the erosion and the database building of the evaluation

and so on

have been discussed.
