摘要
本文提出了松滋河疏浚引水方案,构建了荆江—洞庭湖一、二维耦合整体水动力模型,通过对2003-2008年枯水期径流的模拟,分析了松滋河疏浚引水对洞庭湖区水情的影响。结果表明,松滋河疏浚引水增加了松滋河分流量,对抬高松滋河、七里湖、目平湖枯水期水位效果明显,但对洞庭湖主湖区水位抬高有限,研究成果为缓解洞庭湖区缺水形势提供了重要的依据。
This paper proposes a scheme for the dredging and water pumping program in Songzi river and analyzes the impacts of this program on the water regimes in the Dongting lake area through numerical simulation with a 1D-2D coupling hydrodynamic model. It is showed that the program can effectively increase the runoff diversion from Jingjiang reach of the Yangtze to Songzi river, and make all the water levels in Songzi river, Qili lake and Muping lake become higher. This study provides a support to engineering measures for easing the water shortage in this area.
