| Abstract: | Lake ecosystem services include the supply function,supporting function,regulation and the landscape function,and the extent of these functions affected by the lake hydrological characteristics,water quality, water ecology,spatial physical structure and lake landscape and other factors,meanwhile,the impact factors on the weight are different. The methods to determine the weight include subjective weighting method and the objective weighting method. In this paper,the author appraises ecosystem service functi... |
