水力调度改善城市湖泊水质数值模拟研究

Numerical Simulation Research of Water Diversion to Improve Urban Lake Water Quality

文章利用一维和二维嵌套耦合的湖泊河流水质水量综合模型,模拟水力调度城市湖泊及其连通沟渠水量、水质等的变换过程。以长江、东湖水力调度作为研究对象进行数值模拟,分析不同调水条件下城市湖泊水质的改善效果,数值模拟结果反映了水力调度改善城市湖泊水质的优越性。

In this paper, the lake-river water quantity-water quality intergrated model is applied to imitate the discharge process of water quantity、water quality etc of water diversion on urban lake and it ’s related con-nected ditch. The water diversion between Yangtze River and East Lake is simulated under different condition ,the result shows the superiority of water diversion on improving water quality of urban lake ,and embodies the practi-cability and promotion significance of this model.
