淀山湖湖滨生态修复工程生态湿地设计

Design of ecological wetland for lakeside ecological remediation project of Dianshanhu lake

通过在湖滨拟建3个生态湿地,使3个湿地之间的水域形成静水区,里面种植水生植物,来达到生态修复的效果。通过在湿地内构建不同类型的水生生态群落结构,降低区域蓝藻水华的入侵几率,保障工程局部湖区水质和生态安全。生态湿地填筑采用干挖干填方案,结合生态清淤工程的实施,充分利用湖盆底泥,变废为宝,避免外购土方,对降低工程投资十分有利,可为类似工程参考。

The water area will be the still water area between the three ecological wetlands in planning at the lakeside of Dianshanhu lake, where would plant the aquatic plants to achieving the effect of ecological remediation.Some different structure types of aquatic ecological community are formed to reduce the incidence of breakout of cyanobacteria and water bloom and to ensure the safety of water quality and ecology of partly lake in project area.The ecological wetland would be built by the scheme of the dry digging and dry filling.Combined with the construction of ecological dredging project, the sediment in lake basin could be fully utilized to avoiding the earthworks purchase from other places and reducing the project investment, which would provide some reference for the similar projects.
