摘　　要：西藏自治区人工林林龄偏小,且近年来造林面积逐渐增加,其碳汇功能是天然林的有效补充。根据调查西藏人工林各小班优势树种、林龄、蓄积等数据,建立主要造林树种的单位面积蓄积—林龄模型,根据单位面积生物量—单位面积蓄积模型,推算现有人工林的碳汇潜力。Plantation age composed mainly of young-aged fore.st, and afforestation area gradually increased in recent years in Tibet Autonomous Region, its carbon sequestration function is an effective supplement of natural forest. Based on plantation investigation of Tibet, including the dominant tree species, forest age and accumula tion, the paper established the model between unit stock volume and forest age, and calculation of carbon se questration potential of existing plantations based on unit area biomass-unit stock volume model.
