摘　　要：安徽省长江流域被划为皖江城市带承接产业转移示范区,为国家级示范区,其发展的基础之一则是长江安徽段的河道演变规律及其稳定性,同时水运对城市带的发展有着重要的影响。利用1978年、1989年、1999年和2009年的LandsatMSS/TM、SPOT-5和中巴遥感影像数据,运用RS和GIS技术提取了长江安徽段1978-2009年间河道及湿地动态变化信息;结合研究区地质、地貌、水文调查情况及统计数据等分析了河道及湿地演变特点及其原因,为今后安徽省的发展提供了参考资料。Yangtze River Basin in Anhui Province has been designated as the industrial transfer demonstration region of the city-cluster,as a national demonstration area.One of the foundations of its development is the evolution law and stability of the Yangtze River basin in Anhui.As the same time the water transport has an important impact on the development of Anhui province.This paper used Landsat MSS/TM,SPOT-5 and CBERS-1/2 remote sensing images respectively in 1978,1989,1999 and 2009,combining RS and GIS technology to extract and analyze the dynamic channel and wetland changes of Yangtze River basin in Anhui from 1978 to 2009.With the help of geology,geomorphology,hydrology investigation and statistics data,the paper analyzed the channel and wetland's evolution features and their causes,providing reference for the development of Anhui province.
