摘要
根据海南省白沙县2010年森林资源二类调查报告数据,通过生物量与蓄积量间回归方程推算主要森林类型的生物量和碳贮量,分析不同林龄结构的碳密度,并估算主要森林类型经济价值。结果表明:白沙县主要森林类型的总碳贮量为513.514万t,碳汇总经济价值为616217万元,其中阔叶混交林的碳汇能力最强,其次是橡胶树;人工林面积大于天然林,但碳贮量与天然林相差不大,天然林和人工林的平均碳密度高于我国的平均水平;不同龄组碳密度排序是:过熟林>成熟林>近熟林>中龄林>幼龄林,而中龄级的碳贮量最多,幼龄林最少。
The research aimed to estimate biomass and carbon storage of main types forests by regression equations between stand biomass and stock volume,based on Report of Forest Management Inventory in Baisha County,Hainan Province in 2010,analyzed carbon density of different stage-structures forests,evaluated economic value of main types forests.It shows the total carbon storage of Main type forests in Baisha County has achieved to 513.5,140 t.And the total economic value has reached to 6,162,170,000 RMB.The broadleaf mixed forest holds the strongest carbon sink function,then the rubber tree.The total areas of artificial forest are more than natural forest.However,there is no significant different about carbon storage between artificial forest and natural forest.The average carbon densities of both artificial forest and natural forest are more than national average.The range of carbon density among different stage-structure forests are as follows: over-mature forest> mature forest>near-mature forest>half-mature forest>young forest.Moreover,the half-mature forests hold the most carbon storage.And the young forests hold the least.
