摘要
本研究基于贵州第四次森林资源二类调查数据,利用森林植被生物量与蓄积量的关系,结合支付意愿法,估算了贵州8种不同森林植被类型的碳密度、碳储量和固碳经济价值。结果表明:贵州不同森林植被的平均碳密度为25.87 t/hm^(2),其中,最大的是阔叶混交林(34.55 t/hm^(2)),其次是硬阔林(33.31 t/hm^(2)),最小的是软阔林(16.77 t/hm^(2));总碳储量132.69 TgC,以马尾松林碳储量占比最高,为27.16%,其次杉木林为26.08%,但各森林植被的碳储量因林龄的不同而存在较大差异;总固碳经济价值为230.88×10^(8)元,其变化规律与碳储量的基本一致,其中马尾松林和杉木林固碳经济价值为122.90×10^(8)元,占了总固碳经济价值的53.24%。
Based on the result of the fourth forest resources survey in Guizhou province,the carbon density,carbon storage and carbon sequestration economic value of eight different forest vegetation types in Guizhou were estimated by using the relationship between forest vegetation biomass and stock,combined with the willing-to-pay method.The results showed that the average carbon density of different forest vegetation in Guizhou was 25.87t/hm^(2),of which the largest was broad-leaved mixed forest(34.55t/hm^(2)),followed by hard broad-leaved forest(33.31t/hm^(2)),and the smallest was soft broad-leaved forest(16.77t/hm2).The total carbon storage was 132.69 TgC,with the highest proportion of Pinus massoniana forest,accounting for 27.16%,followed by Chinese fir forest,accounting for 26.08%,and the carbon storage of forest vegetation varies greatly due to different forest ages.The total economic value of carbon sequestration was 230.88×10^(8) yuan,which was basically consistent with the carbon storage.The economic value of carbon sequestration of P inus massoniana forest and Chinese fir forest was 122.90×10^(8) yuan,accounting for 53.24%of the total carbon sequestration economic value.
