综合运用生态学及经济学方法,对高邮湖的9 项生态服务功能,即物质生产、供水、蓄水、行洪 排涝、气候调节、蒸腾吸热、水质净化、科研文化教育和生物多样性维持等功能进行综合价值评估。 结果表明,2009 年高邮湖湖泊生态系统服务功能总经济价值为47.6855 亿元,其中:直接使用价值 为15.2216 亿元,间接使用价值为32.4639 亿元。各生态服务功能价值占总价值的比例排在前三 位的依次是行洪排涝(占26.77%)、蒸腾吸热(占24.05%)、物质生产(占14.21%),表明高邮湖湖 泊生态系统在行洪排涝、蒸腾吸热、水产养殖等方面发挥着重要作用,它们是高邮湖的核心服务功 能。该研究可为高邮湖的生态恢复、水资源保护与管理提供基础。
The economic values of ecological service functions of Gaoyou Lake, including material production, water supply, water storage, flood drainage, climate regulation, transpiration endothermicity, water purification, scientific and cultural education and maintenance of biodiversity, are evaluated by using the comprehensive methods of economics and ecology. The results show that the total values of 9 ecological service functions of Gaoyou Lake in 2009 are 47.6863 billion yuan, and the direct and indirect ones are 15.2216 and 32.4639 billion yuan, respectively. Among them, the flood drainage, transpiration endothermicity and material production are the top 3 functions, which are 26.77%, 24.05% and 14.21% of the total values respectively. The ecological system of Gaoyou Lake plays an important role in flood drainage, transpiration endothermicity, aquaculture and other aspects, and they are the core service functions of Gaoyou Lake. This study may provide the basis for the ecological restoration, water resources protection and management of Gaoyou Lake.
