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

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.
