摘要: "以闽江入海口沿岸上游林区为研究对象,采用生物量推算法对调查资料进行处理,从森林植被类型和林龄两方面分析林区主要森林类型的碳储量和碳密度的分布情况。结果表明:除西部高山区外,碳密度分布从东往西逐渐升高,在人类活动区域碳密度变化范围主要为20~40t/hm2。不同林龄碳储量从小到大排序为中龄林(82171.91t)>幼龄林(43692.93t)>近熟林(18851.71t)>成熟林(5789.81 t),碳密度在针叶林、阔叶林与针阔混交林各林龄分布中均表现为成熟林>近熟林>中龄林>幼龄林。随着龄级的增大,碳密度增大,随着森林的增长,固碳能力逐渐增大。"
英文摘要: "The forest areas of the upper reaches of the Minjiang River estuary are used as the research ob-ject and based on two types of resources survey data in two aspects of forest vegetation types and different age groups,analysis was done on the biomass estimation distribution and the carbon storage and carbon density distribution of the main forest types.The results shows that carbon density distribution in addition to the western mountain area,shows a rising pattern from east to west,carbon density ranges mainly be-tween 20t/hm2 and 40t/hm2 in the area of human activity.The carbon storage of the forests of different ages is in an ascending order as follows:middle-aged forest (82 171.91t)>young growth (43 692.94t)>near mature forest (18 851.71t)>mature forest (5 789.81t),carbon density in different age groups of coniferous forest,broad-leaved forest,coniferous and broad-leaved mixed forest is in an ascending order as follows:mature forest carbon density >near mature forest carbon density >middle aged forest carbon density >sapling forest carbon density.With the increase of age class,carbon density increases,and with the growth of the forests,carbon sequestration capacity increases gradually."
