| 摘 要： | 基于森林资源统计数据，利用生物量转换因子法估算内蒙古大兴安岭满归林区森林碳储量、碳密度，并分析其动态变化特征。结果表明，该林区森林地上总碳储量从2010年的974万t增加到2012年的1 005万 t，年均增长率为1.57%，碳储量主要集中在林区的北部和西部。从树种的角度看，林区总碳储量中落叶松和白桦贡献最大，占据主导地位；从龄组的角度分析，中龄林、近熟林和成熟林占总碳储量的比例很大；乔木林碳密度与林龄紧密相关，先随林龄快速增加而后又缓慢减小。研究时段内，尽管林区整体森林碳密度较小，但不同龄组以及不同森林类型的碳密度总体呈上升趋势。

| Abstract: | Based on forest inventory data,forest carbon storage (FCS) and its dynamics in Mangui Forestry Region was estimated with the method of biomass transfer factor.The results showed that the total FCS in this region increased from 9.74 million tons in 2010 to 10.05 million tons in 2012,with an average annual growth rate of 1.57%.Larix gmelinii and Betula platyphylla played dominant roles in FCS.The middle-aged forests,premature forests and mature forests accounted for a large proportion of total FCS.The arbor forest carbon density was closely correlated to forest age,and it increased quickly with stand age firstly,and then decreased slowly.Carbon densities of different age groups all presented increasing trend,the same as that of the stands with different dominant tree species. |
