关于北江生态流量调度的对策与措施

Ecological Flow Scheduling Solutions of Beijiang River

北江是珠江流域四大水系之一,其干流控制断面石角站来水量不仅能够表征北江流域河道内生态流量情况,还可在珠江三角洲咸潮期配合西江水量调度,控制思贤滘断面进入三角洲水量,对保障粤港澳大湾区供水安全有重要意义。首先对北江流域控制断面生态流量的现状保障情况进行分析,针对存在问题提出水库群调度模型,开展流域内生态流量调度研究,提出北江流域生态流量调度方案。

Beijiang River is one of the four major river systems in the Pearl River Basin.The discharge of its control section Shijiao can represent the ecological flow of the Beijiang River.Additionally,it can also cooperate with the water regulation of Xijiang River during the saltwater intrusion in the Pearl River Delta and control the water volume of the Sixianjiao Section entering the delta,which is significant for the water security of Guangdong-Hong Kong-Macao Greater Bay Area.This paper first analyzes the current ecological flow of the control section of the Beijiang River.Then,the paper builds the reservoir group scheduling model according to the existing problems.Finally,it researches the ecological flow scheduling in the basin to propose an ecological flow scheduling scheme for the Beijiang River.
