The results showed that the carbon densities of different organs were 456.7-479.0 mg·g-1 for Larch plantation in Heilongjiang province. The differences in carbon density of different organs were significant. The carbon densities of different organs varied in the following order: leaf>branch>stem>root. The carbon storage ratios of different ages in various organs were 66.75%-68.92% for stems, 21.59%-22.62% for roots, 5.99%-8.16% for branches and 2.47%-3.50% for leaves, respectively. The proportions of carbon storage of roots and branches increased with growing, while those of stems and leaves presented opposite result. On the whole, the carbon storage of Larch plantation in Heilongjiang province has a tendency of increase from 1986 to 2005 and up to the highest of 30.38 t·hm-2 in 2000. The carbon storage increased at 1.21 t·hm-2 during 1986 and 2005 per year. The ranges of carbon storage for Larch plantation in different areas of Heilongjiang province were 25.43-34.35 t·hm-2 in 2005. The carbon storages of different areas varied in the order: Southern part of Lesser Xing’an Mountains>Wandashan Mountains>Eastern part of Zhang Guangcai Mountains>Western part of Zhang Guangcai Mountains>Northern part of Lesser Xing’an Mountains. %U https://bbr.nefu.edu.cn/EN/10.7525/j.issn.1673-5102.2013.05.021
