摘　　要：为明确区域尺度森林地上生物量碳储量动态特征,采用森林资源规划设计调查数据、解析木数据和加拿大林业碳收支模型(CBM-CFS3),以云南省迪庆州云杉林为例进行研究。2005—2016年迪庆州云杉地上生物量碳储量逐渐增大,范围为9.56~10.69Tg C,碳密度平均值为65.20Mg C/hm^2。树干、其他木(含树皮)碳储量逐渐增加而树叶碳储量逐渐减小,三者碳储量范围为6.81~7.81Tg C、2.12~2.28Tg C和0.60~0.63Tg C;树干、其他木和树叶碳密度平均值分别为47.08 Mg C/hm^2、14.17 Mg C/hm^2和3.95 Mg C/hm^2。地上生物量碳储量年均固碳速率为0.10Tg C/a,表明未来迪庆州云杉地上生物量碳库仍有较大的固碳潜能。This study utilized Carbon Budget Model of the Canadian Forest Sector （CBM-CFS3） to quan- tify the regional-scale forest biomass carbon dynamic by the case of the spruce forest in Diqing Tibetan Autonomous Prefecture of Yunnan, with the data source of Forest Inventory for Planning and Designing and analytical trees. From 2005 to 2016, above-ground biomass carbon stock of spruce forest in Diqing increased gradually from 9.56 to 10.69Tg C, with the average carbon density of 65.20 Mg C ha^-1. The carbon stock of stem and branch （ including bark） increased but the carbon stock of folia declined annually, ranges of which were 6.81-7.81Tg C, 2. 12-2.28Tg C and 0. 60-0. 63Tg C respectively, and average carbon density of which were 47.08Mg C ha-1 , 14. 17Mg C ha-1 and 3.95 Mg C ha^-1 respectively. The annual carbon sequestration rate （0.10Tg C a^-1） suggested that spruce forest in Diqing had the potential ability to sequestrate enormous carbon in the future..
