摘　　要：根据长江口福姜沙河段近年来的水文和地形资料,探讨了该河段河床演变的基本规律,分析了福姜沙沙洲、福姜沙南汊、福姜沙北汊的变化情况。结果表明:福姜沙尾部沙洲仍处在发展的过程中;福姜沙南汊已经趋于稳定;福姜沙北汊深槽的摆动比较频繁,需要在今后的河道治理中重点关注,以保证航道通航。This paper presents an analysis of riverbed evolution of the Fujiangsha river section,which is located at the upstream of the Yangtze Estuary,with the main focus on the recent changes of the Fujiiangsha shoal,the Fujiangsha south branch and the Fujiangsha north branch.The results show that the tail of Fujiangsha shoal is still in the process of development;the south branch is relatively stable;and the main channel of north branch is shifting from time to time,which needs to be paid more attention in the future regulation to ensure the branch navigable.
