摘  要：
随着我国对森林碳汇功能的不断关注,长白山的顶极植物群落红松阔叶林的恢复越来越受到重视。该研究通过干烧法对长白山天然次生林下人工更新红松各器官的含碳系数进行了测定。实验结果表明:红松各器官的含碳系数存在差异,按照含碳系数的高低排序依次为树皮>树干>树叶>树枝>树根,各器官的含碳系数值分别为48.38%、44.39%、43.08%、41.55%、41.33%。红松胸径与根系的含碳系数相关性不大,差异不显著;而树干、树皮、树叶、树枝的含碳系数与红松胸径的相关性较大,差异显著。

摘  要：
With increasing attention to carbon sinks function of forest in China,more attention is paid to the recovery of top plant community, Korean pine broad-leaf forest in Changbai Mountain. This study,by the dry combustion method,measured carbon concentration in various organs of artificial regeneration of Korean pines in natural secondary forest of Changbai Mountain. The experimental results show that: the coefficient of carbon concentration in different organs of Pinus koraiensis is varied,the order of carbon concentration from high to low is stem > leaf > bark > branch > root; the coefficient of carbon concentration of organs is 48. 38%,44. 39%,43. 08%,41. 55%,and 41. 33% respectively. There is no high correlation between diameter at breast height(DBH) and the carbon concentration of root,and the difference is not significant; but there is high correlation between DBH and the trunk,bark,leaves,and branches,and the difference is significant.
