【摘要】：对湿地生态系统服务价值进行定量评价,可以为区域湿地保护管理提供重要的决策依据。结合湖南省第二次湿地资源调查数据和其它相关资料,运用市场价值法和替代法等方法,以2013年为基准年,评价了湖南省湿地所提供的13类生态系统服务价值。结果表明,湖南省湿地生态系统服务总价值为8 631.61×108元,占当年湖南省国内生产总值(GDP)的35.2%,其中,直接价值和间接价值分别为1 340.53×108元和7 291.08×108元,间接价值是直接价值的5.4倍;所计算的13类服务按其价值量依次为涵养水源、调节气候、调蓄洪水、旅游休闲、提供食物与原材料、供水、水电、维持生物多样性、文化教育、航运、固碳释氧、净化水质和保持土壤;湖南省湿地的单位面积生态系统服务价值为84.65×108元/hm2,是2013年湖南省单位国土面积GDP的7.3倍。
[Abstract]:Quantitative evaluation of wetland ecosystem service value can provide important decision-making basis for regional wetland protection and management. Based on the data of the second survey of wetland resources in Hunan Province and other related data, the value of 13 types of ecosystem services provided by wetlands in Hunan Province was evaluated by using the methods of market value method and substitution method and taking 2013 as the base year. The results showed that the total value of wetland ecosystem services in Hunan Province was 8 631.61 脳 10 8 yuan, accounting for 35.2% of Hunan Province's gross domestic product (GDP) in that year. Among them, the direct value and indirect value were 1 340.53 脳 10 8 yuan and 7 291.08 脳 10 8 yuan respectively. Indirect value is 5.4 times of direct value; The 13 types of services calculated in order of value are water conservation, climate regulation, flood regulation, tourism and leisure, provision of food and raw materials, water supply, electricity and electricity, maintenance of biodiversity, culture and education, shipping, carbon sequestration and oxygen release. Purification of water quality and conservation of soil; The ecosystem service value of wetland per unit area in Hunan Province is 84.65 脳 10 ~ 8 yuan / hm2, which is 7.3 times as much as that of GDP per unit land area in Hunan Province in 2013.
