摘  要:
为了应对全球气候变化,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。以南方马尾松为对象,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系统分析。结果表明:马尾松不同器官的含碳系数存在显著差异,从大到小依次为树叶(干材(树根(树枝(干皮;树干不同高度干材和干皮的含碳系数也存在明显差异,但不同层次树枝和不同大小树根的含碳系数差异不显著;不同器官的含碳系数相对比较稳定,与林木起源、直径、树高等因子相关不显著。

摘  要:
To fight the global climate change,forest carbon monitoring is more important,and carbon content factor(CCF)is a key index.Based on the data of Masson pine(Pinus massoniana),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 significantly different,and the order by CCF from the largest to the smallest is foliage,stem wood,root,branch,and stem bark;(ii)the CCF 's of stem wood and stem bark on different heights are significantly different,whereas the CCF 's of branches in different storeys and CCF 's of roots in different size classes are not significantly different;(iii)the CCF 's of different organs are relatively stable,and are not related significantly with the tree origin,diameter and height.
