Using Volume-Biomass methods to estimate trees biomass which is based on the sixth forest resources second-class inventory materials and references relevance to them. Carbon density and storage of different forests in Jiangxi province and Dagangshan Mountains are estimated.1.Carbon storage of forest is 1.18million tons in Dagangshan Mountains.Carbon storage and density of trees are 0.30million tons and 3.136kg.m-2,shrubs and herbs below forest are 0.03million tons and 0.529kg.m-2,its soil are 0.82million tons and 11.564kg.m-2, and its litters is 0.03million tons and 0.324kg.m-2.Carbon density of different forests in Dagangshan Mountains are Softwood forests(19.78kg.m-2),Hardwood forests(19.19 g.m-2),Pubescens forests(17.29kg.m-2),Economic forests(15.70kg.m-2),Coniferous and Broad leaf forests (15.47kg.m-2),Chinese Fir forests(14.93kg.m-2),Masson Pine forests (11.51kg.m-2),Shrubbery(10.62kg.m-2) and Exotic pine forests(9.72kg.m-2).Carbon density of different age of forests are premature forest>mature forest>half-mature forest>postmature forest>young growth forest.Carbon storage of different forests are Pubescens forests(0.41million tons),Chinese Fir forests(0.40million tons),Hardwood forests(0.15million tons),Coniferous and Broad leaf forests(0.12million tons),Softwood forests(0.11million tons),Exotic pine forests(0.07million tons), hrubbery(0.06million tons), Masson Pine forests(0.03million tons) and Economic forests(0.01million tons).2.Carbon density of tree Stratum in different forests in Jiangxi from large to small are Hardwood forests, Coniferous and Broad leaf forests, Pubescens forests, Exotic pine forests, Chinese Fir forests, Softwood forests, Shrubbery, Masson Pine forests, Economic forests. Its carbon storage are Chinese Fir forests(0.054Gt C),Hardwood forests(0.045 Gt C),Masson Pine forests(0.026 Gt C),Pubescens forests(0.025Gt C),Shrubbery(0.024Gt C),Exotic pine forests(0.015 Gt C),Economic forests(0.010 Gt C),Coniferous and Broad leaf forests(0.009 Gt C)and Softwood forests(0.002Gt C).Carbon storage of its southern part and Midwest are larger than its east central and northern part.Carbon storage of different cities are Ganzhou(0.053 Gt C),Jian(0.039Gt C),Shangrao(0.027Gt C),Fuzhou (0.024Gt C),Yichun(0.024Gt C),Jiujiang(0.019Gt C),Jingdezhen(0.007Gt C), Pingxiang (0.006Gt C),Xinyu(0.004Gt C),Yingtan(0.004Gt C) and Nanchang (0.002Gt C) .Total carbon storage of tree stratum in forest in Jiangxi province is 0.210Gt C and it is taken up 5.66 percent in China.3. Trees, aspect, crown density and trees density are also have effects on carbon density, however, position and age haven't. Soil carbon density of Chinese Fir Forests become smaller as trees growing, and it is also smaller when goes deeper.
