摘要
对恩施州柳杉人工林碳汇储量进行了研究,结果显示:柳杉生物量与胸径大小密切相关,全树生物量50%以上集中在树干,各组份生物量分配大致呈现树干>树根(含桩)>叶>枝的趋势.本地区柳杉生物量与胸径、树高的关系模型为W=254.519 7D2.161 4,或W=42.877 2(D2H)0.939 0,采用胸径分布代替年龄结构的方法推算,恩施州柳杉人工林生物量为4 055 704.557 t,碳汇储量为2 038 397.11 t.
The Carbon Sink Storage of Cryptomeria fortunei in Enshi Autonomous Prefecture were discussed in this paper.The results showed that the biomass of Cryptomeria fortunei is related to diameter at breast height.Over 50% of the gress biomass collect in trunks and the distribution is trunksroots（including root pile）leavesbanches.The biomass model of Cryptomeria fortunei related to diameter at breast height and tree height is W=254.5197D^2.1614,or W=42.8772（D^2H）^0.9390.The method of diameter at breast height distribution is used for calculation.The result is that,the biomass of Cryptomeria fortunei artificial forest is 4055704.557t and carbon sink storage is 2038397.11t in Enshi Autonomous Prefecture.
