备注

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。

Eight kinds of main forest types in Hainan province were used as research object to estimate the carbon storage, carbon density and carbon economic value of different types, based on Report of Forest Management Inventory on Hainan province (2008— 2011). Results show that the total forest carbon storage of main types in Hainan has achieved to 34,891,225 t. The range of carbon storage among different stage-structure forests are as follows: half-mature forest> mature forest> near-mature forest > young forest> over-mature forest, the range of carbon density among different stage-structure forests are as follows: mature forest> near-mature forest> over-mature forest > half-mature forest> young forest, the economic value of carbon sequestration amount to 21 748 570 000 yuan. Natural broad-leaved mixed forest is the forest with the largest area ,the largest amount of carbon storage and the highest carbon sequestration value in Hainan. As the most important economic crop, the carbon sequestration contribution in Hainan from rubber tree and eucalyptus plantation should not be underestimated.
