摘　　要：文章利用多时相航卫片遥感图像解译调查分析长江安庆段河道变迁及岸坡崩塌特征。根据解译调查长江安庆段从官洲往下游左岸崩岸不止,近年来,有加大之趋势;而安庆西郊一带则呈淤积态势;其下游马窝段则以崩岸为主,使左汊心滩淤长右移;鹅眉洲则不断崩退,变化趋势明显,应引起水利部门的重视。This paper analyzed the alteration of the Yangtze River course and the features of bank slope collapse in the Anqing section with poly-temporal-phase airborne and satellite remote sensing image. Image interpretation indicated that the left bank collapse had developed continuously downstream from Guanzhou, and speeded up in the recent years, and the part around the western suburb of Anqing City tended to be silted. Bank breakdown dominated in the downstream Mawo section and the channel bar deposit grew to the right side in the left branch of the river; and the Emeizhou bar kept falling down and retreating obviously, to which Water Conservancy Administration should attaches importance.
