摘　　要：弯曲型河道作为一种重要的河流形态,在长江中下游广泛存在,弯曲河道演变复杂,其治理一直是水利、交通等部门关注的热点和难点。在总结三峡水库建库前后长江中下游弯曲河道演变规律、弯曲河道整治理论与治理技术等成果的基础上,提出长江中下游弯曲河道治理应基于河势演变规律和趋势,稳定有利河势、改善不利河势;探讨了未来长江中下游弯曲河道治理的方向,包括少沙背景下弯曲河道长期演化趋向及多目标治理需求,近岸河床长期冲刷下崩岸风险与河道监测预警,防洪-通航等协同综合治理技术及整治新材料应用。As an important river morphology,meandering channels widely exist in the middle and lower reaches of the Yangtze River.Due to the complex evolution,the regulation of meandering channels had always been a hot and difficult issue for water conservancy and transportation sectors.We made a review on the evolution rules,the theories and regulation technologies of meandering channels in the middle and lower reaches of the Yangtze River before and after the construction of the Three Gorges Reservoir.On this basis,we propose that the regulation of meandering channels should be in line with the evolution rules and trends of river regime,stabilizing favorable river regime while improving unfavorable river regime.Furthermore,we delve into the directions of future regulation:the long-term evolution trend of meandering channels under low sediment concentration and the demand for multi-objective regulation,the risk of bank collapse under the long-term scouring of near-shore riverbed and the monitoring and early warning of river channel,as well as the comprehensive regulation technology for flood control and navigation and the application of new materials for regulation.
