四川省湿地生态系统服务功能价值评估

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。
