东湖、北湖以及长江的连通。

阮成发指出,这个构想不仅在改善内湖水质,更在于整个区域436平方公里的生态优化,包括保护生物多样性。

“大东湖”生态水网构建估算投资86亿元,湖泊汇水面积376平方公里。主要工作有4项:清淤截污,对6湖的排污口进行拦截,对沿湖16处雨水排口进行治理,清理东湖、沙湖等水体污染较重区的底泥;引江济湖,使6湖和长江连通,引活水入湖;水网连通,打通东沙湖水系与北湖水系,使东湖东扩,同时实现“大东湖”水系与长江的季节性连通,恢复江湖复合水生态系统的完整性;生态修复,配套建设人工湿地和人工浮岛,重建水生植物系统。

“大东湖”水网构建工程还有一个重要内容:建设生态水网监测、评估研究的仿真平台,探索城市内湖污染控制及治理,为我国南方平原湖区水环境治理、水生态恢复提供借鉴与示范。
