摘要

三峡工程于2003年6月开始蓄水运用,迄今已10 a,坝下游水文情势、河道冲淤与江湖关系等均已发生变化。简要分析了三峡水库蓄水以来长江中游江湖水沙输移特性变化、中游干流河道与三口分流道冲淤变化、中游干流河势变化与江湖关系变化特点;简要介绍了长江科学院近期利用实体模型和数学模型开展三峡工程运用后长江中游江湖演变的预测结果,并与实测资料进行了对比分析;在此基础上就长江干支流水库群联合运用后长江中下游江湖演变研究与治理若干问题进行了探讨,可为未来江湖治理的思路、方案的制定与实施等提供参考借鉴。

Abstract

It’s been 10 years since the Three Gorges Project (TGP) began to operate in June 2003. The hydrological regime, the channel erosion/deposition, and the river-lake relationship in the river downstream of the project has been changing. The variations of flow and sediment transport, erosion/deposition in the mainstream of middle Yangtze River and in the three flow diversion channels, river regime in the mainstream of middle Yangtze River, as well as river-lake relationship are briefly analyzed. The river-lake evolution in the middle Yangtze River predicted by the Changjiang (Yangtze) River Scientific Research Institute (CRSRI) via physical model tests and mathematical modeling are introduced. Comparison between the model predictions and prototype observations are presented. On this basis, the evolution and regulations of rivers and lakes after the joint operation of reservoirs in the upstream Yangtze River are further discussed. The results provide reference for the strategy, formulation and implementation of regulation measures for rivers and lakes.
