摘要
依据呼中林业局2017年森林资源二类调查数据,在分树种、起源、龄组的基础上,采用生物量扩展因子法,对呼中林业局乔木林碳储量、碳密度进行估算和分析.结果显示,呼中林业局乔木林资源总碳储量为29 371 948.3 t,平均碳密度为39.98 t/hm2;天然林碳储量占乔木林碳储量的99.4％,处于绝对优势;兴安落叶松和白桦碳储量占乔木林总碳储量的96.6％,中龄组碳储量最大,占比接近乔木林碳储量的1/2;樟子松林平均碳密度远高于其他树种.
Abstract
Based on the 2017 Type Ⅱ forest resource inventory data of Huzhong Forestry Bureau,the carbon storage and carbon density of arbor forests in Huzhong Forestry Bureau were estimated and ana-lyzed using the biomass expansion factor method,with consideration of tree species,origin,and age group.The results show that the total carbon storage of arbor forest resources in Huzhong Forestry Bureau is 29 371 948.3 tons,with an average carbon density of 39.98 tons per hectare.Natural forests ac-count for 99.4％of the carbon storage of arbor forests,indicating an absolute advantage.Larix gmelinii and Betula platyphylla account for 96.6％of the total carbon storage of arbor forests.The middle-aged group has the largest carbon storage,accounting for nearly half of the arbor forest carbon storage.The av-erage carbon density of Pinus sylvestris var.mongolica forests is much higher than that of other tree spe-cies.
