摘要:
本文简要描述了松滋河复杂的水网体系概况;全面系统分析了松滋河的  形成、演变过程与特征;由于下荆江裁弯等因素,松滋河在三口洪道不断淤积萎缩与分流分沙持续递减演变中,发展为三口最大分流洪道;随后着重论证了三峡枢纽运行后,松滋河口门发生较大崩岸,崩岸产生的泥沙源源不断地输移到口门内宽浅分汊河段沉积,势必加快洪道淤积,加大阻流力度,造成重大河势变化,带来系列负面影响,其要害是加速松滋河的萎缩与衰亡。特别论述了为荆江防洪的长远需要与解决洞北荆南严重缺水问题,需要永远保留松滋河,并做到终年通流的重要性与紧迫性,并提出了相关整治工程措施,可提供规划设计部门参考。

Abstract: The paper briefly describes the complicated water network system of the Songzi River. It comprehensively and systematically analyzes the Songzi River’s formation, evolution and characteristics. The Songzi River develops as the biggest flood channel for shunt under the constant silting-up and the shrink in three outlets and the progressive decrease of sand and flow diversion because of straightening the Jingjiang River’s bend. And then the paper emphasizes that the Songzi estuary comes into being a lager bank caving after the operation of Three Gorge Project. The sediment generated by bank caving continuously moves to the wide and shallow branching channel to deposit, which certainly will speed up the sedimentation of the flood channel, increase the strength of the choked flow, give rise to the great change of river regime and bring about many negative effects. The crucial point is that it will expedite the shrink and decline of the Songzi River. It particularly expounds that we need to always retain the Songzi River for the long-term need of flood prevention of the Jingjiang River and the solution of serious water shortage. The paper points out the importance and urgency to keep the river flow through all the year and puts forward some relative engineering measures for planning and design department to refer.
