摘要
中国地质调查局2005年起实施了"长江流域基础地质环境遥感调查与监测"国土资源大调查项目,工作周期为3年。本文为其子项目——"长江流域水土流失遥感调查与监测"部分研究成果。文章以此次调查成果为依据,选择了经济活力较强经济发展较快的长江中下游地区加以介绍,分析了长江中下游地区水土流失的分布特征,研究了水土流失与基础地质环境的相关因素及其变化趋势,探讨了水土流失遥感调查在基础地质环境调查评价方面的应用情况,供同行们切磋。
China Geological Survey implemented in 2005 the extensive land and resource investigation project "Remote sensing applied in survey and monitoring of basic geological environment of the Yangtze River basin" that spanned 3 years.This paper displayed some research results of its subproject "Remote sensing in survey and monitoring of water and soil loss in the Yangtze River basin",with the focus on the economically active zone,the middle-lower Yangtze River reaches,by analysing the water and soil loss distribution features in the zone and their correlation with basic geological environment and the changing trend.
