Abstract:

Based on the data of the national continuous forest inventory from 2008 to 2013, single tree biomass of larch forest in northeastern China was estimate using biomass compatibility model of different tree species, and summed to plot biomass. Biomass expansion factor (BEF) was calculated to estimate forest biomass, and then biomass was transformed into carbon storage with carbon concentration. With the inventory statistics, carbon storages of provinces at different stages were summarized. The results indicated that: 1) vertical distribution of biomass for larch organs was: stem (48.11%)> root (23.04%)> branch (16.15%)> bark (7.2%)> foliage (4.76%), aboveground biomass made up 76.9% of the total, and root/shoot ratios were raised by age groups. 2) BEF values of larch field plot were reducing by age groups, around an average level of 0.95. 3) total carbon storage of northeastern China was 167.5×106t, based on mid-aged forest, which accounting for 44.22%, the maximum carbon density of mature forest reached to 55.22 t·hm-2, and the mean value of all age groups was only 37.06 t·hm-2, both were far below to the national average. 4) Heilongjiang province carbon storage as 128.35×106 t took the largest percentage of 76.63%, all three provinces had virtually equal carbon density, which increased with age group, but grew slower after near-mature stage.

Key words: northeastern China, larch forest, national continuous forest inventory, biomass, biomass expansion factor, carbon storage
