| 摘 要： | 了解森林生物量碳分配特征,对于森林碳贮量和碳汇估算、森林碳汇经营和生物多样性保护有重要意义.本课题选择福建省万木林自然保护区青年(约47 a生)和老龄(约120 a生)常绿阔叶林为研究对象,根据生物多样性调查结果和生物量异速方程,计算乔木层生物量碳贮量,并分析其高度级、径级和树种间的分配特征.结果表明:1)青年林碳贮量为115.03 t.hm-2,老龄林碳贮量为224.43 t.hm-2;2)青年林最大碳贮量出现在高度级Ⅶ级(15～17 m),为23.17 t.hm-2,而老年林最大碳贮量出现在高度级Ⅷ级(17～19 m),为62.96 t.hm-2;3)青年林中Ⅵ级(15 cm≤DBH<17 cm)的碳贮量最高,为34.25 t.hm-2,占总碳贮量的29.77%;在老龄林中最高碳贮量集中在XIX级(DBH≥41 cm),为60.03t.hm-2,占总碳贮量的26.78%;4)2个林分绝大部分碳贮量都集中在少数树种,大多数物种对碳贮量的贡献很微小.

| Abstract: | In order to investigate the influence of forest biomass carbon on forest carbon storage,carbon sink measurement and management,as well as biodiversity conservation,this paper analyses the evergreen broad-leaved forests,including the young forest(about 47 a)and old-growth forest(about 120 a)in the Wanmulin Nature Reserve in Fujian.According to the results of biodiversity investigation and Biomass Different Speed Equation,we figure out the carbon storage in tree layer and its distribution features in differen... |
