综合调水对苏州河周边水系水质影响的数值模拟

进行长期有效的水资源综合调度是实现2010年苏州河河水变清的综合整治目标的一项重要措施。为进一步论证该项措施对周边水系的水质影响，为综合调水提供科学的决策依据，利用MIKE11模型系统建立了上海市苏州河水系的水动力、水质模型，进行苏州河综合调水对黄浦江以及蕴藻浜水质的影响作用的数值模拟。分析表明，苏州河综合调水对松浦大桥取水口水质基本没有影响，并可以在一定程度上改善黄浦江干流中下游河段的水质；东引北排初期会增加蕴藻浜干流的污染负荷，持续调水6d后蕴藻浜干流河段的水质将得到改善。

Numerical simulation of effect of Suzhou Creek flow augmentation on water quality of its ambient rivers

Long period flow augmentation is one of the key measures to realize the object of making Suzhou Creek clean.In order to demonstrate the effect of flow augmentation on other rivers water quality,water quality model for Shanghai tidal river network was setup and used to numerically simulate the effect of Suzhou Creek flow augmentation on water quality of Huangpu River and Yunzaobang River.The results showed that the effects of flow augmentation of Suzhou Creek will not reach Songpu Bridge though it can improve the water quality of the Middle-stream of Huangpu River.East-to-North will increase the pollution loads to Yunzaobang at the beginning,but 6 days later,North-to-East can improve Yunzaobang's water quality.
