新疆杨树用材林固碳能力分析

Study on Carbon Sequestration Capacity of Timber Production Plantation of Populus sppin Xinjiang

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7200hm2，总蓄积量594600m3，总固碳量达79249593t；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。

Abstract: 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 7200hm2 in Xinjiang, with 594600m3 of stocking volumeThe total volume of carbon storage of the Populous sppplantation in Xinjiang was 79249593t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
