摘　　要：根据《森林生态系统服务功能评估规范》,采用北京市第六次森林资源清查数据、多年观测数据以及公共数据对北京市山地森林的生态服务功能进行评估。结果表明:北京山地森林生态服务功能价值为329.36亿元,各服务功能价值量大小依次为:涵养水源>固碳释氧>保育生物多样性>净化大气>森林游憩>保育土壤>营养物质积累。从涵养水源、积累营养物、保育土壤、净化大气环境、保育生物多样性、固碳释氧6项功能来看,北京山地各森林植被类型生态服务功能价值量排序为灌木林>栎类林>油松林>经济林>侧柏林>阔叶混交林>山杨林>桦树林>刺槐林>落叶松林;从单位面积价值量来看,阔叶混交林所提供的生态服务功能年价值量最大,其次是栎类林,经济林提供的单位面积生态服务功能年价值量最小。Based on the frame of ＂Specifications for assessment of forest ecosystem services in China＂ ,the forest ecosystem ser-vices in Beijing mountain areas were assessed using the long-term observation data,the sixth national forest resource inventory data of Beijing and the price parameter released by the authority department. Results showed that the total value of forest ecosystem services in Beijing mountain areas was 3.293 6×1010 yuan. The values of the ecosystem services were in the following order：water conservationcarbon fixation and oxygen releasedbiodiversity protection atmospheric environment purificationeco-tourismsoil conservationnutrient accumulation. The values of the services for different forest types were ranked as the shrub ecosystem,the oak forest,the Chinese pine forests,the economic forest,the Chinese arborvitae forest,the broadleaved mixed forests,the David poplar forest,the birch forest,the black locust forest and the larch forest from high to low. The broadleaved mixed forests supplied the maximum value per unit area followed by oak forests and economic forests.
