摘要
依据《中国湿地百科全书》及四川省林业厅调查数据,将四川省湿地类型划分为河流湿地、湖泊湿地、沼泽和沼泽化草地、水田湿地、池塘湿地、水库湿地两大类6种类型,采用定量货币化方法对四川省湿地生态系统服务功能价值进行了估算,为四川省湿地保护与规划提供生态经济理论依据。结果表明,四川省湿地生态服务功能的总价值达7 483.03亿元人民币,相当于四川省2009年GDP的52.88%,各项湿地生态功能价值中最高的是固碳释氧功能价值达3 422.00亿元人民币,约占45.73(,其次是水分调节功能和物质生产功能,说明湿地对四川省的生态环境和国民经济有重要作用,并和人们的生产、生活、娱乐密切相关。
Based on the survey data by Forestry Department of Sichuan Province and China′s Wetlands Encyclopedia,wetlands in Sichuan Province was classified into river,lake,marsh and marsh meadow,paddy field,pond and reservoir wetlands.Based on quantitative monetization methods,the functional value of wetlands ecosystem services in Sichuan Province was estimated to provide ecological economic theory basis for wetland protection and planning.The results indicated that the total functional value of wetland ecological service in Sichuan Province reached 748.303 billion Yuan per year,equivalent to 52.88% of GDP in Sichuan Province of 2009.Among every functional value of wetland ecological service,the functional value of carbon fixation and oxygen release was greatest,namely,342.2 billion Yuan and accounting for 45.73% of the total.The second were water regulatory function and material production service function.It indicated that wetlands had significant effect to ecological environment and material production function and closely related to people＇s production,living and entertainment.
