武澄锡低片畅流活水方案研究

近年来，太湖流域武澄锡虞区在城市化迅速发展的背景下，河网整体水动力条件差、污染累积。因此，利用一维河网水动力模型，以武澄锡低片区为研究区域，针对此区域河水动力条件弱、水体自净能力差等问题，以畅流活水提升骨干河网水动力条件为主要目标，模拟5种不同引水结构、不同水源地的调水方式，探究不同水源地引水对研究区的影响。结果表明，在引水规模基本一致时，分布式活水方案的综合改善效果明显好于单一工程集中活水。

Study on Water Transfer Scheme of Wuchengxi Low-lying Area

In recent years,with the rapid development of urbanization in Wuchengxiyu area of Taihu Lake Basin,the overall hydrodynamic conditions of the river network are poor and the pollution in river network is accumulated.In view of the problems of weak hydrodynamic condition of rivers and the poor self-purification capacity of water body in Wuchengxi low-lying area,the water transfer scheme is studied as the main way to improve the hydrodynamic condition of backbone river network in the research area.Based on one-dimensional hydrodynamic model of river network,five water transfer schemes with different diversion structures and different water sources are simulated to explore the influence of water diversion from different water sources on the research area.The results show that when the diversion scale is basically the same,the comprehensive improvement effect of distributed flowing water scheme is significantly better than that of centralized flowing water for a single project.
