珠江三角洲网河区水量水质联合优化调度模型研究

The Model of Water Quantity and Quality Optimal Operation in Pearl River Delta River Network

网河区地势低平、河网纵横、经济发达、人口密集、城镇集中,水资源系统面临快速城市化、海平面上升等多重压力影响,枯水期资源性缺水和水质性缺水并存。以网河区径潮流交互作用机理为基础,以科学调控淡水和微咸水资源为主线,构建了网河区水量水质联合优化调度模型,探讨网河区水量水质优化调控的目标、机理和准则。将此模型运用于珠江三角洲典型感潮区——中顺大围,得出了较好结果。

The river network is a place that is low- lying, freely of a network of waterways, developed, populous, urbanize. Water resources system is facing multiple complex and uncertain factors, such as the rapid urbanization and rising sea levels. It has resulted in water shortage and water quality degradation. Based on the interactions of runoff and tides, as the scientific regulation of freshwater and brackish water resources for purpose, the paper constructed the model of the conjunctive operation of river network s water quantity and quality optimal regulation, and discussed the mechanism, principle and target of the regulation. The model was applied to the typical river network of the Pearl River Delta- Zhongshun Large Polder, and the result is satisfactory.
