摘要
利用浏阳市森林资源二类调查数据(2012年),依据乔木林当中不同林分类型蓄积量与生物量之间的回归方程关系,对浏阳市乔木林的碳贮量进行了推算,分析了不同林种、林龄结构、林分类型以及人工林、天然林的碳贮量及碳密度特征。结果表明:(1)浏阳市乔木林的总碳贮量为4 115 652.91 t,平均碳密度为17.10t/hm2;(2)不同林种之间的碳贮量从大到小依次为用材林>防护林>特用林>经济林,碳密度最大为特用林,为26.99 t/hm2,其他阔叶林的碳贮量最大,占乔木林碳贮量的41.83%,其次是杉木林;(3)不同龄组间碳贮量分布的基本规律为中龄林>近熟林>成熟林>幼龄林>过熟林,碳密度变化趋势基本随着年龄的增加而增大。浏阳市的人工林与天然林的碳贮量相差不大,天然林碳密度水平高于人工林。
By using forest resource survey data of Liuyang（2012）, the biomass and carbon storage of arbor in Liuyang were estimated with the method of regression equation between biomass and volume in different forest types,calculated and analyzed the carbon storage and carbon density of different sorts of forestand different age-structure and the carbon distribution between plantations and natural forests.The results show that： （1）The carbon storage of Liuyang’s arbor totaled 4 115 652.91 t, average carbon density is 17.10 t/hm2; （2）Carbon storage from big to small in different sorts of forest is timber forest〉 shelter forest〉special using forest〉economic forest,special using forest have the highest carbon density（26.99 t/hm2）, Other broad-leaves trees have the biggest carbon storage, the proportion is as high as 41.83%,then followed by Cunninghamia Lanceolata forest; （3）The basic regularity on carbon density of different age is half-mature forest〉 near-mature forest〉 mature forest〉 young forest〉 over ripeness forest. Plantation and natural forest carbon storage in Liuyang city were similar, Natural forest is higher than plantation forest in the aspect of carbon density.
