粤港澳大湾区水安全协同调控理论框架研究

Theoretical framework of water security collaborative regulation and control in Guangdong-Hong Kong-Macao Greater Bay Area

针对粤港澳大湾区水问题多维交织特性,基于流域系统整体观梳理总结了技术上可控、逻辑上关联的5个水安全调控子系统结构,包括:河势调控子系统、内河水环境水生态调控子系统、外江咸潮调控子系统、城市暴雨洪涝调控子系统、外江洪潮调控子系统。探讨了各子系统关键机理、系统间的协同作用原理、协同调控的关键技术需求及协同调控模型算法架构,构建了大湾区水安全协同调控理论框架,以珠江河口为例开展了粤港澳大湾区水安全协同调控理论的应用,为大湾区水问题系统治理提出了新的解决方案。

In view of multidimensional interwoven characteristics of water problems in the Guangdong-Hong Kong-Macao Greater Bay Area,this study summarized the structures of five technically controllable and logically related water security regulation and control subsystems,including river regime control subsystem,inland waters environment and ecology regulation subsystem,outer river salt tide regulation subsystem,urban rainstorm and flood regulation subsystem,and outer river flood tide regulation subsystem,and discussed key mechanisms of the subsystems,the principle and key technologies for collaborative requlation,and the collaborative model algorithm framework.Then a theoretical framework of water security collaborative regulation and control in the Guangdong-Hong Kong-Maca Greater Bay Area was constructed.As a case study,the water security collaborative regulation and control theory was applied to Pearl River Estuary,providing new solutions for the systematic management of water problems in this area.
