引水调度改善太湖流域无锡市运东片区水环境方案研究

Research on the Water Diversion Scheme on Water Environment Improvement in the Yundong District of Wuxi City in Taihu Basin

针对太湖流域近年来水质恶化问题,探究引水调度对太湖流域水环境改善效果。选取太湖流域典型区无锡市运东片区为研究区域,构建一维非稳态水动力水质模型,模拟各引水方案及调度规则对研究区域的水质改善效果。结果表明:白屈港与锡澄运河同时引水调度方案与澄西片引水调度方案结合能够有效改善研究区域水质,各断面水质类别有明显提升,总体水质达标率从现状31.0%提升至65.5%。

In view of the problem of water quality deterioration in Taihu Basin in recent years,the effect of water diversion dispatch on water environment improvement in Taihu basin was studied.The Yundong District of Wuxi City was taken as the research area,and a one-dimensional unsteady hydrodynamic water quality model was constructed to simulate the water quality improvement effect of each water diversion scheme and dispatching rule on the research area.Results show that the simultaneous water diversion of Baiqu Port and Xicheng Canal combining with the water diversion scheme of Chengxi area can effectively improve the water quality of the research area.The water quality of each section has been significantly improved,and the overall water qualification rate has increased from 31%to 65.5%.
