摘要
以新疆西伯利亚云杉为对象,运用假设检验与回归分析,对其含碳系数进行逐步分析。结果表明:干材上部、根茎的含碳系数大于同一器官其他部位;地上部分平均含碳系数为0.456 5;全株不同器官平均含碳系数为0.461 9,大小顺序为干皮>树叶>树枝>树根>干材;云杉各器官及全株含碳系数相对稳定,不随胸径、树高、年龄等因素变动。建议根据不同树种采用相应实测含碳系数。
The carbon coefficient of Picea obovata Ledeb in Xinjiang was analyzed by using hypothesis tes-ting and regression analysis.The research conclusions are as follows：the upper part of the trunk and rhizo-me of carbon coefficient is greater than the other parts of the same organ;The average carbon coefficient of the ground is 0.4565;The average carbon content in different organs of the whole plant is 0.4619,and the order by CCF from the largest to the smallest is stem bark,foliage,branch,root,and stem wood;The rela-tive stability of various organs and the whole plant carbon coefficient is not changed with the increase of diameter at breast height,tree height,age and other factors.According to different tree species,the corre-sponding measured carbon coefficient shall be used.
