摘　　要：为了探究内蒙古固阳县不同灌木人工林植被层的固碳速率,以固阳县3种常见灌木人工林树种(柠条,沙棘,山杏)为研究对象,通过实地标准木取样,建立各树种生物量模型,结合空间代替时间的方法,对研究区内3种常见灌木林树种进行碳含量测定,并分析估算不同灌木树种的碳密度和固碳速率。结果表明:固阳地区3种不同灌木不同林龄人工林植被层固碳速率为0.12~1.0 t hm^(-2)·a^(-1),其中柠条人工林植被层固碳速率为0.12~0.38 t hm^(-2)·a^(-1),沙棘人工林植被层为0.12~1.0 t hm^(-2)·a^(-1),山杏人工林植被层为0.22~0.68 t hm^(-2)·a^(-1)。In order to investigate the carbon sequestration rate of vegetation layer of different shrub artificial forests in Guyang County of Inner Mongolia,three common shrub artificial forest tree species(Caragana korshinskii,Hippophae rhamnoides,and Prunus sibirica)were selected as the research object.Through on-site standard wood sampling,biomass models of each tree species were established,and the method of space replacing time was used to measure the carbon content of three common shrub forest tree species in the study area.The carbon density and carbon sequestration rate of different shrub tree species were analyzed and estimated.The results showed as follows:the carbon sequestration rate of the vegetation layer in the artificial forests of three different shrubs and different forest ages in Guyang area ranged from 0.12 t hm^(-2)·a^(-1) to 1.0 t hm^(-2)·a^(-1),with the carbon sequestration rate of the vegetation layer in the artificial forests of Caragana korshinskii ranging from 0.12 t hm^(-2)·a^(-1) to 0.38 t hm^(-2)·a^(-1),the carbon sequestration rate of the vegetation layer in the artificial forests of Hippophae rhamnoides ranging from 0.12 t hm^(-2)·a^(-1) to 1.0 t hm^(-2)·a^(-1),and the carbon sequestration rate of the vegetation layer in the artificial forests of Prunus sibirica ranging from 0.22 t hm^(-2)·a^(-1) to 0.68 t hm^(-2)·a^(-1).
