陈行水库应对咸潮入侵的运行分析与思考

Analysis and Consideration of Chenhang Reservoir Operation in Response to Salt Water Intrusion

咸潮是海水涨落潮造成上游河道水体变咸的一种自然现象,枯水期间严重威胁着长江口陈行水库水源地的取水安全。文中在分析陈行水库运行调度现状和陈行水库应对咸潮措施的基础上,通过汇总分析长江口咸潮入侵历史数据以及2014年特大咸潮侵袭过程,提出了陈行水库咸潮期运行调度的优化方案以及根本解决咸潮期陈行水库库容不足的相关建议。

Salt water intrusion is a natural phenomenon that the upstream river becomes salty due to the fluctuating intrusion of sea water.It seriously threatens the water intake safety of the source area of Chenhang Reservoir in the Yangtze Estuary during the dry season.Based on the analysis of the operation and dispatching status of Chenhang Reservoir,measures are taken to deal with the salt water intrusion.The paper puts forward the optimization scheme of the operation and dispatching of Chenhang Reservoir during the salt water intrusion period,and relevant suggestions to solve the shortage of storage capacity of Chenhang Reservoir during the salt water tide period,by collecting and analyzing the historical data of extra ordinary salt water intrusion in 2014.
