国外不同类型湖泊治理思路分析与启示

Analysis of Lake Management Strategies of Different Types of Lakes Abroad and Enlightenments for China

  • 摘要: 为给我国湖泊水污染控制与富营养化治理提供可借鉴的思路与经验,选取位于日本、欧洲、北美等地的17个湖泊进行案例剖析,根据这些湖泊的自然特征(湖泊面积、平均水深与水体功能)将其分为大中型浅水湖泊、深水湖泊以及景观(小型)湖泊三种典型类型。通过资料整理分析、对比研究和集成凝练等技术手段,分析三类湖泊的治理思路及治理技术。分析得出,湖泊治理应坚持不懈、持续治理;在良好规划的基础上,分阶段科学治理;重视长期监测与基础研究;以污染源控制为基础,多种技术手段并用;进行生态修复,保持湖泊自然生态特征;加强流域管理,并重视立法、环境教育与公众参与。

     

    Abstract: Cases of 17 lakes from Japan, North America and Europe were studied in order to provide guidelines and experience for the pollution control and treatment of eutrophication in domestic lakes. According to the differences in area, average depth and function of the water body, the lakes could be divided into three types: large or medium-sized shallow lakes, deep lakes, and landscape (small) lakes. Various analytical methods including data analysis, comparative study and data integration were employed to analyze the control strategies and techniques of the three types of lakes. Based on the results, the following summaries could be drawn: a) the lake management should be persistent; b) the control should follow a stepwise scientific procedure based on good planning; c) attention should be paid to the long-term monitoring and basic researches; d) source control of pollutants using integrated methods should be the primary task; e) ecological remediation should be performed in order to restore the natural ecosystem in the lakes; f) watershed management should be strengthened, and legislation, environmental education and public participation be encouraged.
