荆江与洞庭湖汇流区演变分析

 对荆江与洞庭湖汇流区的水沙过程变化及河道演变等进行了分析，认为其主要的影响因素是江湖关系的调整变化、洞庭湖人工围垦和泥沙淤积、江湖汇流区下游河道变化以及上游来水来沙变化等。可供江、 湖治理和三峡枢纽下游河道可能发生的演变及工程措施的研究参考。

Analysis on Fluvial Processes of Confluence Area of Jingjiang River and Dongting Lake

In the paper, the changes of flow and sediment process and fluvial processes of confluence area of the Jingjiang River and Dongting Lake are analyzed, and their main influence factors, including the adjusting changes of river and lake relation, the reclamation and sediment accumulation of Dongting Lake, the changes of downstream reaches of river and lake confluence area and of incoming water and sediment etc., are also discussed. The study results may be used for reference to study the improvement of the Jingjiang River and Dongting Lake regulation, and the possible fluvial processes and engineering measures for the TGP's downstream river channel.
