摘　　要：近几十年来，随着对长江河道的整治及崩岸的治理，长江安徽段河势趋于稳定，岸崩有所遏制，但与之相伴的河道淤积却有扩展之势。为了解长江安徽段泥沙淤积现状，利用1987—2001年秋季（9～11月）ETM数据，结合该地区1980年以来TM图像与航片资料，对长江河道、沙洲及其湖泊湿地围垦现状进行解译分析，为长江水患防治及环境地质问题的治理提供基础资料。In recent decades, with the remediation of Yangtze River and the control of bank collapse, the situation of rivers along the Yangtze River in Anhui Province has trended to be stable and the bank collapse has been checked to some extent. However, the concomitant river siltation seems to expand. In order to find out the present situation of sedimentation along the Yangtze River in Anhui Province, this paper made an interpretation and analysis of the Yangtze River sandbank and lake reclamation using ETM satellite images from 1987 to the autumn of 2001 in combination with TM satellite images and airborne data obtained in this area since 1980. The results provide the basic information for harnessing the Yangtze River flood and solving environmental geological problems.
