摘要
基于联合国千年生态系统评估框架,建立了景东县森林生态系统服务价值评估指标体系,采用市场价值法、替代工程法等,结合森林资源调查数据对云南省景东县森林生态系统服务的物质量和价值量进行了定量评价。结果表明,景东县森林生态系统服务总价值为259.43亿元/a,其中,提供产品服务价值为7.78亿元/a,调节服务价值为154.89亿元/a,支持服务价值为92.19亿元/a,文化服务价值为4.57亿元/a;森林生态系统服务总价值是该县林业总产值和国内生产总值的33.34倍和5.12倍;不同生态服务提供的价值大小顺序为保育土壤>固碳释氧>涵养水源>净化大气环境>提供产品>森林游憩>生物多样性保护。不同森林类型提供的生态服务价值大小顺序为思茅松>栎类>针阔混交>阔叶混交>软阔>栲类>云南松>桦木>铁杉>针叶混交>杉木>华山松>桉树。
Based on the millennium ecosystem assessment, this study established the indicator system of forest ecosystem services value in Jingdong County, and by using the physical and value assessment meth- ods combined with the forest management inventory data, we evaluated the forest ecosystem services value of Jingdong County of Yunnan Province. The results showed that the total value of Jingdong County forest ecosystem services was 259.43 ×10^8 yuan per year, of which provisioning services value was 7.78×10^8 yuan per year, regulating services value was 154.89 ~ 108 yuan per year, supporting services value was 92. 19 ×10^8 yuan per year and cultural services value was 4.57×10^8yuan per year. The total value of forest ecosystem services was 33.34 times of the forestry production value and 5.12 times of the GDP of the Jingdong County. The value of different services could be arranged from the maximum to the minimum value as： soil conservation, carbon sequestration and oxygen release, water conservation, atmosphere en- vironmental purification, product offers, forest recreation and biodiversity conservation. The ecosystem services value of different forest types could be arranged from the maximum to the minimum value as ： Pi- nus kesiya, Ouercus, conifer - broadleaved mixed forest, Broadleaf mixed forest, soft broadleaf,Castan- opsis,Pinus yunnanensis , Betula, Tsuga chinensis , coniferous mixed forest, Cunninghamia lanceolata , Pinus armandii, Eucalyptus robusta.
