摘　　要：以第4次森林资源连续清查数据为依据,用蓄积量法对新疆杨树用材林的各龄组进行固碳能力分析,结果显示:新疆杨树用材林的总面积是7 200 hm2,总蓄积量594 600 m3,总固碳量达792 495.93 t;各龄组固碳量分别为近熟林占67.84%,中龄林占13.61%,幼龄林占18.55%;各龄组的单位蓄积量以及碳密度均是近成、过熟林大,中龄林最小。The carbon sequestration capacity of the timber production plantation of Populous spp. in Xinjiang was studied by age groups based on the data of 4th forest resource inventory and by means of the stocking volume methodology. The results showed that the total area of poplar timber production plantation was 7 200 hm2 in Xin- jiang, with 594 600 m3 of stocking volume. The total volume of carbon storage of the Populous spp. plantation in Xinjiang was 792 495.93 t. The carbon storage of the pre-mature stands, the middle aged stands and the young stands accounted for 67. 84% , 13.61% and 18.55% respectively. Both of the stocking volume and the carbon density per unit area of the pre-mature stands and the post-mature stands were higher than those of the middle-aged stands and the young stands.
