Approaches to the Ecological Rehabil itation of Lakeside Zone of Taihu Lake

Abstract

太湖湖滨带是太湖流域重点污染控制区之一.本文根据流域生态学与流域管理学的原理,提出了太湖湖滨带生态建设的途径.(1)发展生态农业,减少农田污染.(2)入湖河道沿岸两侧建设河岸林带,成为农田与河流间的缓冲带.(3)加强沿岸丘陵的水土保持.(4)充分利用湖泊湿地的净化功能,作为治理太湖富营养化的有效措施.(5)选择入湖河道河口,在试验基础上建立人工湿地.推动太湖湖滨带生态建设工程顺利开展的措施:(1)提高全社会的环境保护意识.(2)从组织和制度上加强湖滨带污染控制管理.(3)建立环境监测和信息管理系统.(4)开展湖滨带污染控制工程的试验研究.;The lakeside zone of Taihu Lake is one of the major pollution control regions in Taihu basin.Based on the principles of watershed ecology and management the measures of ecological rehabilitation for lakeside zone in Taihu Lake were put forward in the paper.(1) To develop eco-agriculture should be the effective way to reduce agricultural pollution.(2) Riparian forest belt as a buffer zone between farmland and water body, should be planted along the rivers that enter Taihu Lake.(3) Soil and water conservation should be paid particular' attention to in the hills on lakeside.(4) Fulfilling purification function of lake wetlands is the proper method to prevent eutrophication of Taihu Lake.(5) Man-made wetland system at the mouth of rivers that enter Taihu Lake should be established on the basis of experiment in selected place. Suggestions are made for the purpose of a ccomplishing the ecological rehabilitation of lakeside zone i.e.: 1) To heighten the public consciousness for environmental protection; 2) to strengthen pollution control and management of lakeside zone on the basis of organization and regulation; 3) to establish environmental monitoring and information system, and 4) to advance the tentative ideas for further study of pollution control engineering of lakeside zone.
