Abstract:

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/m3;biomass expansion factor(BEF)was 1.39;root shoot ratio(R)was 0.14;basic wood density(WD) was 0.61t/m3.(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.

Key words: larix gmelini, biomass conversion and expansion factor, biomass expansion factor, rootshoot ratio, basic wood density
