元荡湖生态修复工程的实践与探讨

Practice and Discussion of Ecological Restoration Project of Yuandang Lake

受温室效应和人类活动的双重影响,我国湖泊水域面积正在急剧缩减,湖泊生态系统的重要功能,如供水、调节气候、沟通航运、繁衍生物等大幅度降低乃至丧失,严重影响了资源可持续利用和区域经济发展,因此湖泊生态修复问题亟待解决。本文整理并分析了上海市元荡湖存在的问题,利用湖区现状构建了包含湖、湾、池、湿地、河等多种水体形态的层次水体净化网络,探究了湖泊滨水岸线生态修复技术在元荡湖的应用方式。通过岸线贯通及水生态提升等修复措施,元荡湖修复工程区域内水质得到了一定改善。该修复工程为构建协调的流域生态格局、促进区域经济社会可持续发展及改善人居环境提供了一定的建设性意见及思路。

Due to the double impact of greenhouse effect and human activities,the area of lake water is shrinking rapidly,and the important functions of lake ecosystem,such as water supply,climate regulation,shipping linkage,reproduction and so on,are greatly reduced or even lost,which seriously affects the sustainable utilization of resources and regional economic development.Therefore,the problem of lake ecological restoration needs to be solved urgently.This paper sorts out and analyzes the existing problems of Yuandang Lake in Shanghai,constructs a hierarchical water purification network including lake,bay,pool,wetland,river and other water bodies by using the current situation of the lake,and explores the application of lake waterfront and shoreline ecological restoration technology in Yuandang Lake.The water quality in the area of Yuandang Lake restoration project have been improved.The restoration project provides some constructive suggestions and ideas for constructing the coordinated ecological pattern of the basin,promoting the sustainable development of regional economy social and improving the living environment.
