摘　　要：采用常规和替代市场评估技术,对祁连山北坡东段哈溪林区有机质生产、水源涵养、水土保持、固定CO2和净化空气5种生态系统服务功能间接价值进行了估算,并对3种不同植被类型的生态服务功能价值进行了比较。结果表明,哈溪林区5种服务功能总价值为52061.00万元,其中森林、灌丛和草地分别为19510.34万元、25200.01万元和7350.65万元。按有林地面积推算,祁连山森林生态系统提供的服务功能间接经济价值是天祝县国民生产总值的3～5倍,森林生态系统所提供的生态服务功能价值远远超过了当地社会创造的经济价值。就水源涵养和水土保持服务功能而言,灌丛提供的总价值最大。By using conventional and surrogate market approaches,estimation was made on the indirect monetary values of forest ecosystem services,including organic matter production,water and soil conservation,CO2 fixation,and air purification,in Haxi forest area at the east part of northern slope Qilian Mountains.In the meantime,the ecosystem services values of three vegetation types were compared.The total value of the five ecosystem services in the forest area was 5.2061×108 yuan,among which,woodland occupied 1.951034×108 yuan,shrub land occupied 2.520001×108 yuan,and grassland occupied 0.735065×108 yuan.Calculated by forest land area,the monetary value of indirect ecological services provided by the forest ecosystem in Qilian Mountains was as 3-5 times as that of the Gross National Product in Tianzhu County.Among the three vegetation types,shrub land had the largest monetary values of water and soil conservation services.
