摘　　要：对20世纪90年代以来开展的长江中下游航道整治工程建设经验进行总结,统计航道现状和已建、在建和拟建的航道整治工程概况,从滩槽演变、高滩岸线、汊道分流、航道尺度对工程建设整治效果进行评价,并对后续航道建设中存在的问题进行分析。对比工程实施前后的航道条件,已建工程对影响航道条件的洲滩、岸线实施系统守护,稳定了河势及滩槽格局,全面提升航道水深及稳定性,工程河段航道条件得到显著改善,为后续治理奠定良好基础。We summarize the channel regulation engineering construction experience of the middle and lower reaches of the Yangtze River since the 1990s,gather the current situation and the general situation of constructed,under-construction and awaiting projects,evaluate the regulation effectiveness from the aspects of evolution of shoals and channels,shoreline,high beaches,branch division ratio,channel dimension,and analyze the problems of the subsequent construction.Contrasting the channel conditions before and after the implementation of the project,we find that constructed projects succeed in many aspects,such as systematically protecting river beaches and shorelines,stabilizing river regime and the situation of shoals and channels,increasing channel depth and improving channel conditions of constructed reaches.The constructions of channel projects lay foundation for future regulation.
