基于海南省森林资源二类调查报告(2008—2011),本文以海南省八种主要森林类型作为研究对象,对不同森林类型的碳贮量、碳密度及经济价值进行估算。结果表明:海南森林总碳贮量为3 489.122 5万t,碳贮量按龄级分布状况为中龄林>成熟林>近熟林>幼龄林>过熟林,碳密度按龄级分布状况为成熟林>近熟林>过熟林>中龄林>幼龄林,主要森林类型平均总经济价值2 174 857万元。天然阔叶混交林是海南面积最大、碳贮量最大,碳汇价值最高的林种;而作为海南重要的经济作物,橡胶树与桉树类人工林对海南森林碳汇贡献不可低估。
Based on the second type of forest resources survey report (2008-2011) in Hainan Province, eight main forest types in Hainan Province were selected as research objects to estimate the carbon storage, carbon density and economic value of different forest types. The results showed that the total carbon storage in Hainan was 3 489.122 50000 t, and the distribution of carbon storage according to age class was middle-aged forest> mature forest> near-mature forest> young forest> over-mature forest. The situation is mature forest> near-mature forest> over-mature forest> middle-aged forest> young forest. The average total economic value of main forest types is 2 174 857 thousand yuan. Natural broad-leaved mixed forest is the largest Hainan Province, carbon storage and carbon sinks highest value of forest species; and as an important cash crop in Hainan, rubber tree and eucalyptus plantations of Hainan forest carbon sink contribution can not be underestimated.
