浅水湖泊水环境的生态修复研究

Study on Ecological Restoration of Shallow Lake Water Environment

卧龙湖位于沈阳市康平县,是辽宁省最大的平原淡水湖。为了维护生态系统稳定性和安全性,本文结合流域生态现状,依据生态修复的总体原则,采取多项措施对卧龙湖水环境进行生态修复。一是布设浮式消浪防沙系统,实施消浪防沙;二是重建湖滨带湿地生态系统,改善水质;三是消解湖底沉积物,实现资源化利用。其间通过环保清淤对内源污染负荷进行削减,利用湖底沉积物营造滨湖浅滩和生态岛,恢复水生植物群落,提升水体自净能力,使湖区水质持续改善,生态系统结构与功能不断优化。

Wolong Lake,located in Kangping County,Shenyang City,is the largest plain freshwater lake in Liaoning Province.In order to maintain the stability and safety of the ecosystem,combined with the current ecological situation of the watershed,this paper adopts multiple measures for ecological restoration of the water environment of Wolong Lake based on the overall principles of ecological restoration.One is to install a floating wave and sand control system to implement wave and sand control;the second is to rebuild the wetland ecosystem in the lakeside zone and improve water quality;the third is to digest the sediment at the bottom of the lake and achieve resource utilization.During this period,the internal pollution load is reduced through environmental dredging,and the lake bottom sediments are used to create lakeside shoals and ecological islands,restore the aquatic plant community,improve the self purification ability of water bodies,so that the water quality in the lake area is continuously improved,and the structure and function of the ecosystem are constantly optimized.
