Jiangxi Province, the sixth Forest resource inventory data and related biomass literature is based on the use of volume source of biomass on the forest carbon density of the forest area in Jiangxi Province JNU Kong characteristics and distribution of carbon storage were studied. The results are as follows: 1. The forest area Dagangshan forest ecosystem carbon stocks is 1.18 × 10 6 t, trees, vegetation is 0.30 × 10 6 t, understory vegetation 0.03 × 10 6 t, soil 0.82 × 10 6 t, litter was 0.03 × 10 6 t; carbon density of the tree layer 3.136kg.m -2 , understory vegetation 0.529 kg.m -2 , the soil is 11.564 kg.m -2 , litter matter of 0.324 kg.m -2 . Dagang forest area forest type in carbon density of soft broad-leaved forest (19.78kg.m -2 ), hardwood forest (19.19kg.m -2 ), hair bamboo forest (17.29kg.m -2 ), forest (15.70kg.m -2 ), needle broad-leaved mixed forest (15.47kg.m -2 ), Chinese fir (14.93kg.m -2 ), in Masson Pine (11.51kg.m -2 ), bush (10 . 62kg.m -2 ), exotic pine (9.72kg.m -2 ), different age forest carbon density of near-mature forest gt; mature forest gt; middle-aged forest gt; mature forest gt; young forest. Carbon stocks of different forest types in the order of Moso bamboo (0.41 × 10 6 ), Chinese fir (0.40 × 10 6 ), hard broadleaved forest (0.15 × 10 6 ), mixed coniferous (0.12 × 10 6 ), soft broadleaved forest (0.11 × 10 6 ), exotic pine (0.07 x 10 6 ), bush (0.06 × 10 6 ), masson pine (0.03 × 10 6 ) and forest (0.01 × 10 < / sup>). The Jiangxi forest tree layer carbon reserves of 0.210 G t C, accounting for 5.66% of the total carbon stock of the national forest tree layer. Jiangxi different forest types in the tree layer carbon density hardwood forest gt; conifer and broadleaf mixed forest gt; the Bamboo Forest gt; the exotic pine gt; the Chinese fir gt; soft broad-leaved forest gt; shrubbery gt; horsetail pine gt; forest. Different forest types of vegetation carbon storage fir forest (0.054Gt C), hardwood forest (0.045 Gt C), masson pine forest (0.026 GT C), the Bamboo Forest (0.025Gt C), the bush (0.024Gt C), exotic pine (0.015 GT C), forest (0.010 Gt C), conifer and broadleaf mixed forest (0.009 GT C) and softwood forest (0.002Gt C). Jiangxi forest carbon density of vegetation presented from south to north, from east to west is progressively decreasing carbon reserves in the South and Midwest than in the east and north. Carbon storage in the geographical distribution of the order of Ganzhou (0.053 GT C), Ji'an City (0.039Gt C), the Shangrao City (0.027Gt C), the Fuzhou City (0.024Gt C), the Yichun City (0.024Gt C), Jiujiang City, ( the 0.019Gt C), the Jingdezhen City (0.007Gt C), the Pingxiang City (0.006Gt C), the Xinyu City (0.004Gt C), of Yingtan City (0.004Gt C) and Nanchang (0.002Gt C). Species, aspect, canopy density and stand density on the carbon density, slope position and age had no significant effect. With age and increasing soil depth fir forest soil carbon density decreased.
