摘　　要：基于内蒙古大兴安岭林区第四次至第六次复查期(1994-2008年)的森林资源数据,利用不同森林类型生物量和蓄积量之间的回归方程,估算大兴安岭林区森林生物量和碳储量,分析大兴安岭林区森林碳储量和碳密度变化规律。结果表明:在近15年间,大兴安岭林区森林面积呈持续增长的趋势,此期间森林碳储量也呈逐渐增加的趋势,其值变化规律为350.052 TgC(第六次复查)>330.468 TgC(第五次复查)>285.431 TgC(第四次复查)。不同复查期的森林碳密度变化规律为第六次复查>第四次复查>第五复查。从林龄方面来看,三次复查期内,森林碳储量变化规律为中龄林>成熟林>近熟林>过熟林>幼龄林,碳密度的变化规律为过熟林>成熟林>近熟林>中龄林>幼龄林。落叶松林和桦木林是大兴安岭林区的主要森林类型,在15年复查期内,落叶松林和桦木林面积、生物量和碳储量均呈逐渐增加的趋势,其中落叶松林的贡献率最大。Based on the data of fourth to the sixth review survey（1994-2008） of the Da Xing Mountains forest resource,regression equation between the biomass and volume of different forest types,the biomass and carbon stocks in Da Xing Mountains forest were estimated.The study shows that,during the recent 15 years,forest area in Da Xing mountains showed a growth trend,forest carbon stocks during this period had a growing trend,its value changed as follows： 350.052TgC（sixth review survey）＆gt; 330.468TgC（fifth review survey）＆gt; 285.431TgC（fourth review survey）.The forest carbon density changing was the sixth period＆gt; fourth period＆gt; fifth period.From the forest-age,the variation of forest carbon storage was the half mature forest＆gt; mature forest＆gt;near mature forest＆gt;over mature forest＆gt; young forest;carbon density variation was： over mature forest＆gt; mature forest＆gt; near-mature forest＆gt; half mature forest＆gt; young forest.Larch and birch mixed forest was the main forest type in the Da Xing mountains.During its 15-years review survey period,the distribution area,biomass and carbon storage continued to show an increasing tendency,the larch took the greatest contribution.
