Abstract

In order to measure the carbon concentration in different organs of the Larix olgensis tree with different ages, eight trees of them, which have the age between 7.5 and 46 years, were measured with dry combustion method by using Vario EL III element analyzer. The errors in estimates of carbon stock were examined by using 0.5 while ignoring ages or intra-specific variations. The results show that: the weighted mean carbon concentration of Larix olgensis by biomass was approximately 48.15%. In this study, the carbon concentration of aboveground tree organs is ranked with descending order as living branch>barkp>foliage>dead branch>stem; and in the belowground, it is ranked as large roots>stumps>thick roots>medium roots>small roots. The carbon concentration differs significantly between tree organs, while there is no significant difference between trees with different ages.
