三峡工程建设对洞庭湖的影响研究综述

Research overview on the influence of the Three Gorges project construction on Dongting Lake

河流上游修建水库会改变河流下游自然的水文过程,下游河流及通江湖泊的各种变化与上游水沙过程的改变有着千丝万缕的联系。三峡工程运行后将会对长江中下游特别是洞庭湖产生何种影响是众多学者关注的焦点。在阅读了近百篇关于三峡工程建设对洞庭湖的影响研究的论文和相关资料的基础上,综述了洞庭湖对三峡水库建设的响应,从三峡运行以来对洞庭湖水情和淤积的变化、荆江三口分流分沙的变化以及城陵矶水位流量的演变等方面进行了总结和综述,并展望了今后的研究趋势与方向,以期对三峡工程与洞庭湖的关系进一步研究提供参考。

Reservoir construction in an upper reach of the river may change the natural hydrological process in the river downstream. Water and sediment process change of the downstream river and lake which links to the river are related closely to the changes of the Upper reaches. Many scholars are interested in that what kind of influence will produce on the middle and lower reaches of Yangtze River, especially the Dongting Lake after the operation of the Three Gorges project on the Yangtze River. On the basis of reading nearly 100 articles related to the influence of the construction of the Three Gorges Project on the Dongting Lake, this article reviews the responses of the Dongting Lake to the construction of the Three Gorges Reservoir. The water and sediment situation changes, the flood and sediment diversion changes of the Jingjiang River, and the evolution of Chenglingji water level and flow of the Dongting Lake after the operation of the Three Gorges Reservoir are summarized, and the trends and directions of future research on this subject was also prospected. This work will provide reference for further study on the relationship between Dongting Lake and the construction of Three Gorges project.
