上海市主要河流调水方案的水质影响分析

针对上海市平原感潮河网的特点,对全市河网的水流、水质调度情况进行了详细分析,并利用MIKE11建立了上海市平原感潮河网的水动力和水质模型,同时数值模拟和分析了全市主要河流调水方案对水质的影响.结果表明,通过水利工程的合理、科学调度运行,全市骨干河流的水质可以得到一定程度的改善,部分河段的水质甚至可以提高1~2个水质等级.

Influence of water diversion schemes on water quality of Shanghai river networks

In consideration of the characteristics of the plain tidal river network in Shanghai City,an analysis was made of the current situation of water flow and water quality dispatching among the river network.A hydrodynamic model and a water quality model were developed for the tidal river network of Shanghai City by use of MIKE11,and the models were applied to simulation and analysis of the influences of water diversion schemes for main rivers on water quality of the river network.The result shows that the water quality of main rivers can be improved to a certain degree by scientific operation of hydraulic projects,and in some river sections,the water quality can be improved by 1-2 levels.
