分析总结了太湖生态治理措施和方法，利用数值模拟方法建立太湖平面二维水动力、水质模型，根据东南风、西北风和东北风不同主导风组合下的计算结果，分析太湖流场变化规律和太湖湖区流线变化形态。基于人工导流，减少太湖无效闭合环流，提高太湖污染物置换率的考虑，提出一种新思路，在太湖内结合清淤、航道疏浚及景观美化工程建设导流堤，阻隔太湖在风力作用下形成无效的“死”循环系统，有组织地引导、控制水体流动，从而促进湖体的有序水循环，大幅度、高效地改善太湖调水清污效果。结果表明，在太湖配合引水工程修建导流堤，对促进太湖污染物置换有明显的改善作用，与原始工况相比，导流堤方案五对太湖污染物置换率的改善相对明显，污染物置换率有明显提高。

The ecological treatment measures and methods in the Taihu Lake were analyzed and summarized, andthe numerical simulation method adopted to establish a two-dimensional plane hydrodynamic and water qualitymodel.According the simulated results of different dominant wind direction combinations of southeast, northwestand northeast, the flow field variation regularities and streamline variation forms of the Taihu Lake were analyzed.Under the new idea of reducing invalid closed circulation system and improving the contaminant exchange ratethrough artificial diversion, the construction of diversion dike with the combination of sludge dredging, waterwaydredging and landscaping engineering in the Taihu Lake was proposed, which could barrier the invalid endless loopsystem forced by wind, organize and guide the water flow, promote water cycle, and then improve the clean-upeffective significantly.The results show that it plays an obvious role in promoting contaminant exchange rate of theTaihu Lake.Among the five diversion dike schemes, Scheme 5 is the optimal one with most obvious improvement ofthe contaminant exchange rate.
