摘要/Abstract

摘要： 森林的固碳释氧功能对缓解全球气候变暖发挥着重要作用,因此森林碳储量监测日益受到重视,而含碳系数是一项重要的基础计量指标。以东北落叶松为对象,利用假设检验和回归分析方法,对不同器官的含碳系数进行了系统分析,结果表明:落叶松不同器官的含碳系数大都存在显著差异,从大到小依次为:干皮﹥树枝﹥树叶﹥树根﹥干材;树干上部的含碳系数明显大于中部和下部,但中部和下部的含碳系数没有显著差异;不同大小树根的含碳系数差异不显著,树根与地上部分的含碳系数也没有显著差异;不同器官的含碳系数相对比较稳定,与林木直径和树高等因子无关,但全树尤其是树根生物量的含碳系数与起源相关显著。

Abstract: The function of forests for fixing carbon and releasing oxygen gives full scope to relieve the global climate warming,thus forest carbon monitoring is more important,and carbon content factor (CCF)is a key index. Based on the data of larch (Larix spp)in northeastern China,the CCF’s of different organs were analyzed systematically using hypothesis test and regression analysis. The results showed:(i)the CCF’s of different organs are almost significantly different,and the order by CCF from the largest to the smallest is stem bark,branch,foliage,root,and stem wood; (ii)the CCF of upper stem wood is significantly larger than those of middle and lower stem woods,whereas the CCF’s of middle and lower stem woods are not significantly different; (iii)the CCF’s of roots with different sizes are not significantly different,and the CCF’s of root and aboveground biomass are also not significantly different; (iv)the CCF’s of different organs are relatively stable,and are not related significantly with the tree diameter and height,but the CCF of whole tree,especially the CCF of root,is related significantly with the tree origin.

Key words: carbon content factor, biomass, hypothesis test, regression analysis, Larix
