摘　　要：以联合国政府间气候变化专门委员会(IPCC)指南为依据,以内蒙古大兴安岭兴安落叶松(Larix gmelini)人工林为研究对象,根据实测生物量数据,计算兴安落叶松人工林碳计量参数,结果表明:1)生物量转化与扩展因子(BCEF)平均值为0.92t/m^3,生物量扩展因子(BEF)平均值为1.39;根茎比(R)平均值为0.14;木材基本密度(WD)平均值为0.61t/m^3;2)回归分析发现:BCEF,BEF,WD均与林龄(A)、平均胸径(DBH)呈负相关,均与林分密度(D)无明显相关,R与A,DBH,D均无显著相关性;3)IPCC指南缺省值与碳计量参数实测值估算生物量结果差异显著,本研究可为进一步校正IPCC法中碳计量参数,准确估算森林碳储量提供基础数据。Based on the United Nations Intergovernmental Panel on Climate Change(IPCC)guide,the carbon parameters of larch plantations in inner Mongolia′s Daxing’anling forest area were calculated based on the measured Biomass data.The results showed that:(1)Biomass conversion and expansion factor(BCEF)was 0.92 t/m^3;biomass expansion factor(BEF)was 1.39;root shoot ratio(R)was 0.14;basic wood density(WD)was 0.61t/m^3.(2)regression analysis showed that BCEF,BEF and WD were negatively correlated with(age)A and DBH,while not significantly corrlative with D.There is no significant correlation between R A,DBH and D.(3)There are significant differences between the default values of IPCC guidelines and the measured values of carbon parameters in biomass estimation.This study can provide basic data for further correction of carbon measurement parameters in IPCC method and accurate estimation of forest carbon reserves.
