摘  要:
以湖南省马尾松纯林为对象,利用假设检验和回归分析方法,对马尾松林木各器官以及全林木含碳系数进行了回归检验分析。结果表明:林木各器官的含碳系数在统计上大都存在显著差异,树干不同高度处干材的含碳系数从上到下总体上呈逐渐增大的趋势,不同粗细树根的含碳系数根茎到细根、粗根依次减小,根茎、细根、粗根两两之间并无显著差异;83株解析木地上部分的平均含碳系数为0.506 6,28株解析木树根的含碳系数为0.491 9,全林木生物量的平均含碳系数为0.505 2;林木不同器官及全林木生物量的含碳系数与林木直径和树高没有相关性。

摘  要:
Based on the data of pure Pinus massoniana forest in Hunan province,the carbon content factor(CCF) of different organs and the whole tree were analyzed using hypothesis test and regression analysis.The results showed that,in statistics the CCF of different organs were almost significantly different,stem wood's CCF increased from the top to the down.The order by CCF of different thickness roots from highest to the smallest was rhizome,thin root and thick root,there was no significant difference among them.The average CCF of the 83 parse trees was 0.506 6,root's average CCF of 28 parse trees was 0.491 9,average CCF of whole tree's biomass was 0.505 2.The CCF of different organs and whole tree's biomass were not related to its diameter and height.
