洪泽湖湿地生态系统服务功能货币化评价

Study on functions of wetland ecosystem assessment in Hongze lake

采用市场价值法,从生态系统服务功能分析的角度对我国第四大淡水湖之一的洪泽湖的服务价值进行货币化评估.结果表明:(1)洪泽湖其鸟类、植物产品、旅游价值、科研文化价值等直接使用价值为52 503×104元,占总价值的10.07%;(2)间接使用价值(固定CO2及释放O2价值、涵养水源及调蓄洪水价值、控制水土流失和侵蚀价值、废物处理价值和生物避难所价值)为30 4307.7×104元,占总价值的58.38%.目前非使用类价值、有选择价值、遗产价值和存在价值为164 467×104元,占总价值的31.55%;(3)洪泽湖湿地每年服务于人类的各种价值总和可达52×108元人民币.洪泽湖湿地生态系统服务价值评估可为其他湿地价值评价和生态恢复与保育提供借鉴.有关洪泽湖湿地生态系统功能与结构有待进一步研究.

Application of the way for the eco-environmental economy, we have estimated the ecosystem function of the the Hongze lake wetlands in the value of the monetary assessment. The results showed that China＇s Hongze lake as the fourth largest fresh -water lake and the Huang-Huai Plain and subtropical North middle and lower reaches of the Yangtze River within the transitional zone of a typical inland freshwater wetlands, birds, plant products, tourism value, research and cultural value, such as direct use Value of 525.03 million yuan, accounting for 10.07% of the total value; indirect use value （fixed value of CO2 and the release of O2, water conservation and flood storage value, control soil erosion and corrosion of values, values＇and biological waste treatment haven value） 3. 043 077 billion yuan, accounting for 58.38%. The present value of non - use category, choose the value of heritage value and the value of 1. 644 67 billion yuan, accounting for 31.55%. Hongze lake reached the eastern part of wetlands each year of service in the human value of up to 5.2 billion yuan. On Hongze lake wetland ecosystem function and structure pending further study, as well as other wetlands and evaluation of the value of ecological restoration and conservation for reference.
