摘　　要：应用1991～1992年美国第二代陆地卫星资料，和1954年、1966年、1981年航空遥感资料等五个时相镇扬段长江岸线图，进行同名点（控制点）扣合并经比较得出结论：本段长江南岸严重淤积，使镇江港封堵；北岸大量崩退，使本段长江槽向北迁移了2．5km．The images of second generation landsat (1991～1992) and aerial photos (1954,1966, 1981) were applied in the investigation. The changes of Zhangjiang river bank Zhengjiangarea in the above mentioned five different periods has been detected by piecing together andchecking up these remote sensing damages. It comes to the conclusion that Zhangjiang's southernbank in this section has been heavily deposited, making the Zhengjiang port almost choked withsilt, while the northern bank has collapsed massively and moved 2500m to the north.
