珠江河口复杂河网的水资源调度方案评价EI北大核心CSCD

为评价珠江河口河网的水资源调度方案,以横琴中心沟水系为研究区域,针对原调度方案存在的调水规模问题,结合横琴中心沟水系、外江潮汐和水环境特征优化了调度方案,并提出以水体交换能力为评价指标,对原调度方案和优化方案进行了评价。结果表明:原调度方案水体交换能力不足,优化方案调水幅度增加后,半交换周期普遍缩短,水交换率提高,可以满足规划水质目标。

Evaluation of water resources regulation scheme for complex river network in the Pearl River Estuary

In order to evaluate the water resources regulation scheme for the river network in the Pearl River Estuary, taking the water system of Hengqin central ditch as the research area, aiming at the problem of water transfer scale in the original regulation scheme, combined with the characteristics of Hengqin central ditch water system, the tidal characteristics of the outer river and the characteristics of water environment, the regulation scheme was optimized. The water exchange capacity was proposed as an index to evaluate the original regulation scheme and the optimized scheme. The results show that the water exchange capacity of the original regulation scheme was insufficient. After the water transfer range was increased in the optimized scheme, the half exchange period was generally shortened and the water exchange efficiency was improved, which could meet the planned water quality objectives.
