摘　　要：文章以2021年内蒙古大青山国家级自然保护区森林资源数据为基础,依据《森林生态系统服务功能评估规范》(GB/T 38582-2020),从保育土壤、林木养分固持、涵养水源、固碳释氧、净化大气环境和森林防护6个方面,测算保护区主要优势树种的森林生态系统服务功能物质量,以期为保护区森林资源监测、评价和生态保护修复提供决策性依据。结果表明:在乔木林地中,白桦(Betula platyphylla)林地面积最大(41 058.364 9 hm^(2)),其所提供的生态服务功能物质量相对较高;尽管华北落叶松(Larix gmelinii var. principis-rupprechtii)林地面积最小(4 718.584 8 hm^(2)),但其单位面积蓄积量相对较高(90.04 m^(3)/hm^(2)),其所提供的生态系统服务功能高于榆树(Ulmus pumila)和油松(Pinus tabuliformis)。在灌木林地中,柄扁桃(Prunus pedunculata)和虎榛子(Ostryopsis davidiana)林地面积相对较大,其所提供的生态系统服务功能物质量相对较高。因此,森林生态系统服务功能与森林面积、森林质量有直接关系。Based on the forest resource data of Daqing Mountain National Nature Reserve in Inner Mongolia in 2021,this study quantifies the ecosystem service functions of the main dominant tree species in the reserve according to the Assessment Specifications for Forest Ecosystem Services(CB/T 38582-2020).The study focuses on six aspects:soil conservation,nutrient retention in trees,water conservation,carbon sequestration and oxygen release,air purification,and forest protection.The aim is to provide decision-making support for the monitoring,evaluation,and ecological protection and restoration of forest resources in the reserve.The results show that among the arboreal forests,the area of birch(Betula platyphylla)forests is the largest(41058.3649 hm^(2)),and the ecosystem service function quantity it provides is relatively high.Although the area of Dahurian larch(Larix gmelini var.principis-rupprechti)forests is the smallest(4718.5848 hm^(2)),its volume per unit area is relatively high(90.04 m^(3)/hm^(2)),and the ecosystem service function it provides is higher than that of Ulmus pumila and Pinus tabuliformis.In the shrub forests,the areas of Prunus pedunculata and Ostryopsis davidiana forests are relatively large,and the ecosystem service function quantity they provide is relatively high.Therefore,the ecosystem service functions are directly related to the forest area and forest quality.
