摘要
以山西省2005年的森林资源清查数据为基础,采用生物量换算因子法,建立了不同林分优势树种生物量与蓄积量之间的回归方程,并对山西省森林的碳贮量进行了推算。结果表明:山西省森林的总碳贮量为4 684.56×104t C,平均碳密度为21.99 t C/hm2;其中针叶林碳贮量为1 689.69×104t C,阔叶林碳贮量为2 994.87×104t C,分别占全省森林总碳贮量的36.07%和63.93%。阔叶林为山西省森林碳贮量的主要贡献者。
Based on the basis of forest resource data investigated in Shanxi province in 2005, the regression equation between biomass and the amount of growing stock in different stand dominant species was built and carbon storage of forest vegetation in Shanxi province was calculated. The results showed that： the total carbon storage of forest vegetation in Shanxi province is 4 684.56× 10^4 t C the average of carbon density is 21. 99 t C/ hm2, of which coniferous forest is 1 689.69× 10^4t C, broadleaf forest is 2 994.87× 10^4t C, accounting for 36.07% and 63.93% of the total carbon storage of the whole province forest, respectively. Broadleaf forest is the main contributor to the carbon storage of the Shanxi province forest.
