摘　　要：近年来,长江上游温中坝河段河床地形及演变特性发生改变,对通航条件的影响较大,枯水期需要通过航道养护疏浚才能保障航道尺度。掌握温中坝河段河床演变特性和原因是实施精准养护工作的前提,也是制定和实施生态航道建设的重要依据。通过多年实测资料分析,揭示了温中坝河段近年来河床演变的特性和主要原因,针对河床演变带来的航道条件变化,提出了航道维护对策及治理思路。研究结果对温中坝河段航道维护与航道治理具有较大的实用价值。In recent years,siginificant alterations have been observed in the riverbed topography and evolutionary characteristics of the Wenzhongba section in the upper reaches of the Yangtze River.These alterations have had a considerable impact on navigational conditions,particularly during the dry season,necessitating channel maintenance dredging to ensure navigational dimensions.Acquiring a comprehensive understanding of the riverbed′s evolutionary characteristics and the underlying reasons is crucial for precise maintenance implementation and serves as a foundation for the formulation and execution of ecological waterway construction.Through the analysis of multi-year field data,this paper reveals the distinctive features and primary causes of the recent riverbed evolution in the Wenzhongba section.Addressing the changes in navigational conditions resulting from riverbed evolution,the paper puts forward strategies for channel maintenance and governance.The insights provided in this paper hold substantial practical value for the effective maintenance and governance of the Wenzhongba section′s waterway.
