摘要 应用辽宁省森林资源林地变更数据,采用蓄积量-生物量转换模型法和平均生物量法,结合不同树种含碳率,对辽宁省主要树种的碳储量和碳密度进行估算,并分析不同林种的碳储量分布特征。结果表明:天然林的碳储量为防护林>用材林>薪炭林>特种用途林>经济林,其中防护林占比达66.7%;碳储量针叶林<阔叶林,碳密度阔叶林<针叶林。人工林碳储量为用材林>防护林>特种用途林>薪炭林>经济林,其中用材林占比达58.3%;其次是防护林(38.2%);碳储量针叶林>阔叶林,碳密度是针叶林>阔叶林。全部森林资源碳储量中,防护林与用材林占全部林种的95.1%,用材林的碳密度比较大,而经济林的碳密度最小。 Using the change data of forest resources and forest land in Liaoning Province,using the volume-biomass conversion model method and the average biomass method,combined with the carbon content of different tree species,the carbon storage and carbon density of the main tree species in Liaoning Province were estimated,distribution characteristics of the carbon storage of different forest species were analyzed.Result shows that:The carbon storage of natural forests is protection forest>timber plantation>firewood forest>forest for special use>non-timber product forest,of which protection forest account for 66.7%;needle-leaved forest for carbon storage<broad-leaved forest,broad-leaved forest for carbon density<needle-leaved forest.The carbon storage of plantation is timber plantation>protection forest>forest for special use>firewood forest>non-timber product forest,among which timber forest accounts for 58.3%;followed by protection forest(38.2%);needle-leaved forest for carbon storage>broad-leaved forest,carbon density is needle-leaved forest>broad-leaved forest.Among all carbon reserves of forest resource,protection forest and timber forest account for 95.1%of all forest category.Timber forest have a relatively high carbon density,while non-timber product forest have the smallest carbon density.
