为提高水资源调度改善水质效果,利用黄浦江水系、崇明岛河网水量水质模型,在分析评估上海市水资源调度现状效果的基础上,从引排水口门配置、水闸开启方式、水位控制条件等方面考虑,研究分片水资源调度优化方案。通过引排水量大小、水质改善效果等多方案分析比较,提出了分片水资源调度优化方案。结果表明：分片COD平均浓度改善3.1%~16.9%；分片NH3-N平均浓度改善3.4%~28.1%。 COD浓度为：劣吁类水的河网面积减少37.1%,Ⅲ类水的河网面积增加33.4%；NH3-N浓度为劣吁类水的河网面积减少9.4%,Ⅳ~Ⅲ类水的河网面积增加25.9%~31.0%。

In order to improve water quality through water resources scheduling, the river network quantity and quality models of the Huangpu River network and the Chongming Island river network were used in this study. Based on the analysis and assessment of current effects of water resources scheduling in Shanghai City, the optimization schemes of water resources regionalization scheduling were studied, considering the configuration of diversion and drainage water gates, the opening and closing of water gates, and the water level controlling conditions. Through comparison of different schemes with different amounts of water diversion and drainage, and different water quality improvement effects, optimized water resources regionalization scheduling schemes were established and their effects were identified. The results show that, using the optimized schemes, the concentration of COD decreased by 3.1% to 16.9% on average, and the concentration of NH3-N decreased by 3.4% to 28.1%on average. The river network area where the concentration of COD was inferior to class V decreased by 37.1%, and the area where the concentration of COD was at class III increased by 33.4%. The river network area where the concentration of NH3-N was inferior to class V decreased by 9.4%, and the area where the concentration of NH3-N was between class III and IV increased by 25.9 % to 31.0%.
