对18年生樟树人工林生物量、碳素含量、贮量及其空间分布进行测定.结果表明,樟树各器官的碳素含量为42.12%～55.42%,排列顺序为树叶＞树枝＞树根＞树干＞树皮.林冠上层与下层叶的碳素含量比中层叶的碳素含量低,但差别不大;下层枝条碳素含量明显比上、中层枝条高.灌木层植物的碳素含量平均为51.30%,草本植物为48.90%,死地被物层为40.89%.土壤的碳素含量为1.25%,随土层深度的增加,各层次土壤碳素含量逐渐减少.樟树林生态系统总的碳贮量为200.44×103kg C?hm-2,其中乔木层为45.01×103kgC?hm-2,占整个生态系统总贮量的22.45%,灌木层为2.29×103kgC?hm-2,占1.14%,草本层为1.09×103kg?C?hm-2,占0.55...

The biomass,carbon content,storage and distribution in Cinnamomum camphora plantation were studeied.The results showed that carbon content in different organs of C.camphora trees ranged from 42.12% to 55.42%,and decreased in the order of leaf > branch > root > bole > bark.In the canopy,the carbon content varied with layers.Carbon content in the leaves of upper and lower layer was lower than that in the leaves of the middle,and carbon content in the branch of the lowelayer was higher than that of the middle and the upper.The carbon content in sh...
