摘　　要：以长江中下游扬中河段小泡沙汊道为例,通过对汊道历史演变及现有问题的总结,提出对小泡沙洲头以及右汊采取相应的治理措施的必要性,并使用数模软件分别比选了洲头和右汊的两种方案。最终采用洲头守护加右汊护底的组合方案,以期一定程度上遏制右汊分流情况的继续恶化。Based on the summary of the historical evolution and existing problems of the branch channel in the Yangzhong reach of the middle and lower reaches of the Yangtze River,the necessity of taking corresponding control measures for the head of Xisha island and right brunch is proposed.And the two schemes of the head and right branch are compared with each other by using numerical simulation software.Finally,the combined scheme of protecting the head of the island and protecting the bottom of the right branch was adopted to curb the deterioration of the distributary flow of the right branch to a certain extent.
