基于2009年庐山森林资源二类调查小班数据库和一类调查样地调查数据,利用CBM-CFS3模型的估算功能,估算江西庐山2009年森林生态系统碳储量。结果显示:庐山森林生态系统碳储量为6.4 T g(T=106t,t=106g),各主要森林类型之间因森林面积大小不同其碳储量差距很大;其中马尾松碳储量最大,占总碳储量的41.64%,国外松最小为2.18%。庐山森林生态系统平均碳密度为262.55 t/hm2,其中混交林碳密度最大为365.95 t/hm2,杉木碳密度最小为194.96 t/hm2。利用一类样地数据和平均生物量法得到庐山森林生态系统生物量碳密度为32.87 t/hm2,与模型计算结果 31.86 t/hm2基本一致。庐山总生物量碳库碳储量占庐山生态系统碳储量的12.47%,死有机质(DOM)碳库占比为87.53%,土壤碳库在整个生态系统中占有很大的比例为66.30%。
Based on the investigation data of the second class of Lushan forest resources survey database and the survey sample of a kind of surveyed plots in 2009, the carbon storage of forest ecosystem in Lushan, Jiangxi Province in 2009 was estimated by using the estimation function of CBM-CFS3 model. The results showed that the carbon storage of forest ecosystem in Lushan Mountain was 6.4 T g (T = 106t, t = 106g), and there was a big gap in carbon storage among the main forest types due to different forest areas. Among them, 41.64% of carbon storage, the minimum for foreign pine is 2.18%. The average carbon density of forest ecosystem in Lushan Mountain is 262.55 t / hm2, among which the maximum carbon density in mixed forest is 365.95 t / hm2, and the minimum carbon density in Chinese fir is 194.96 t / hm2. The biomass carbon density of the forest ecosystem in Lushan Mountain was 32.87 t / hm2 using a sample of the same type of data and the average biomass method, which was basically consistent with the model calculation of 31.86 t / hm2. The total carbon storage of Lushan Mountain accounted for 12.47% of the total carbon storage in the Lushan Mountain ecosystem, and the proportion of DOM carbon pool was 87.53%. The soil carbon pool accounted for 66.30% of the total ecosystem.
