摘　　要：以黑龙江省、吉林省、内蒙古自治区东部(东经117°6′~135°5′,北纬41°25′~53°23′)的国有林区为研究对象,以阔叶混交林、樟子松林、杨桦林、落叶松林4种林型为森林生态系统构成要素,采用替代市场法、影子工程法、条件价值法等常用的环境价值评估方法,对黑龙江省、吉林省、内蒙古自治区等省(区)国有林区的涵养水源、保育土壤、固碳释氧、积累营养物质、净化大气环境、保护生物多样性等6个方面生态系统服务价值量进行监测与评估,分析不同区域、不同林型对生态系统的服务功能。结果表明:东北国有林区生态系统服务功能差异显著,吉林省、黑龙江省、内蒙古自治区森林生态服务总价值量,分别为7047.71、6539.77、5169.8亿元·a-1;东北国有林区生态系统服务功能差异较大,6个生态系统服务价值量占生态系统服务功能总价值量比例,由大到小依次为森林涵养水源价值量、固碳释氧价值量、保育土壤能力价值量、净化大气环境价值量、营养物质积累价值量、生物多样性保护价值量。对吉林省、黑龙江省、内蒙古自治区的4种林型森林生态系统服务功能价值量分析表明,不同地区、相同林型间生态系统服务价值量差别较大;虽然森林生态系统各服务功能价值量最大的林分类型不能确定,但樟子松林在所有服务功能中价值量均为最低。We took the state-owned forests regions as our research areas, including the eastern part of Heilongjiang Province, Jilin Province and Inner Mongolia Autonomous region (117°6′-135°5′E, 41°25′-53°23′N). We used the methods of market value, shadow engineering, and condition value to calculate the six parameters of ecosystem service in water conservation, water conservation, soil conservation, carbon sequestration and oxygen release, nutrients accumulation, atmospheric purification and biodiversity conservation in broadleaf mixed forest, pine forest, birch forest and larch forest. There were significant differences in ecosystem service functions in the state-owned forest regions in northeast China. The total value of forest ecological services in Jilin Province, Heilongjiang Province, and Inner Mongolia Autonomous region was RMB 704.771, 653.977 and 516.98 billion·a -1 , respectively. Differences of quantity proportion of the six ecosystem services value in the total value was followed by water conservation, carbon and oxygen release, soil conservation, atmosphere purification, nutrient accumulation quantity, and biodiversity conservation. Different forest types exist significance difference of ecosystem service value, the larch forests in all research areas have the lowest service functional value, but the highest express variously.
