浅水湖泊生态清淤试点研究——以巢湖为例

Analysis on Pilot Project of Environmental Dredging in a Typical Shallow Lake——Chaohu

近年来,随着经济的持续高质量发展,水环境问题越来越受到人们的关注,而生态清淤(环保疏浚)作为河湖综合治理中较为有效的方法受到了广泛的应用,越来越多的流域开始谋划大规模生态清淤,但是不同地区的底泥污染程度及污染特性不同,难以全盘借鉴,因此以巢湖为例探讨在大规模清淤前开展试点清淤的必要性,经分析论证,推荐南淝河入湖口作为生态清淤试点区,面积5.52 km^(2),平均清淤深度0.29 m。

With the concept of sustainable and healthy development gradually receiving widespread popular supports,water quality has been targeted as a major a concern.As a treatment of endogenous pollution,the environmental dredging of sediment has been widely applied in the comprehensive treatment of water environment.Large-scale dredging planning carried out in more and more basins while pollution property and intensity are widely divergent in different cases.Taking Chaohu as an example for shallow lakes,a pilot project before dredging in an entire lake is essential through the thorough analysis and demonstration,and the pilot area is recommended as 5.52 km^(2) with the dredging depth of 0.29 m which is set at the estuary of river nanfei.
