摘要
本文利用长江干、支流主要控制站近60多年水沙序列和实测地形资料,探讨长江流域不同河段、不同时段的水沙变化和河床冲淤情况,在分析长江上游来水来沙变化特性的基础上,较为系统地研究了三峡水库蓄水运用以来,水库泥沙淤积和坝下游河床冲刷演变特性,不仅有助于对长江流域不同河段进行河道整治与洪水治理,还可为三峡工程运行、管理,长江黄金水道建设、长江经济带建设以及长江大保护战略的研究和实施提供可靠的科学依据。
In this paper,we use the water and sediment sequences and measured topographic data of the main control stations of the Yangtze River and the tributaries for more than 60 years to explore the water and sediment changes and riverbed erosion and sedimentation in different sections of the Yangtze River basin and different periods.Based on analyzing the variation characteristics of incoming water and sediment in the upper reaches of the Yangtze River,this paper systematically studies the sedimentation and sedimentation evolution of the reservoir downstream of the Three Gorges Reservoir.This will not only help river regulation and flood control in different river sections of the Yangtze River Basin,but also provide a reliable science for the operation and management of the Three Gorges Project,the construction of the Yangtze River Golden Waterway,the construction of the Yangtze River Economic Belt and the research and implementation of the Yangtze River conservation strategy.
