【摘要】 以江西省第六次森林资源二类清查资料和相关的生物量文献为依据,运用材积源生物量法对江西省暨大岗山林区的森林碳密度特征和碳储量分布进行了研究。研究结果如下:1.大岗山林区森林生态系统总碳储量为1.18×10⁶t,乔木植被为0.30×10⁶t,林下植被为0.03×10⁶t,土壤为0.82×10⁶t,枯落物为0.03×10⁶t;乔木层碳密度为3.136kg.m^-2,林下植被为0.529 kg.m^-2,土壤为11.564 kg.m^-2,枯落物为0.324 kg.m^-2。大岗山林区不同森林类型的碳密度为软阔林(19.78kg.m^-2)、硬阔林(19.19kg.m^-2)、毛竹林(17.29kg.m^-2)、经济林(15.70kg.m^-2)、针阔混交林(15.47kg.m^-2)、杉木林(14.93kg.m^-2)、马尾松林(11.51kg.m^-2)、灌木林(10^.62kg.m^-2)、国外松林(9.72kg.m^-2),不同年龄森林的碳密度为近熟林>成熟林>中龄林>过熟林>幼龄林。不同森林类型碳储量依序为毛竹林（0.41×10⁶）、杉木林（0.40×10⁶）、硬阔林（0.15×10⁶）、针阔混交林（0.12×10⁶）、软阔林（0.11×10⁶）、国外松林（0.07×10⁶）、灌木林（0.06×10⁶）、马尾松林（0.03×10⁶）和经济林（0.01×10⁶）。2.江西省森林乔木层的总碳储量0.210^Gt C,占全国森林乔木层总碳储量的5.66%。江西省不同森林类型乔木层碳密度为硬阔林>针阔混交林>毛竹林>国外松林>杉木林>软阔林>灌木林>马尾松林>经济林。不同森林类型植被碳储量为杉木林（0.054Gt C）、硬阔林（0.045 Gt C）、马尾松林（0.026 Gt C）、毛竹林（0.025Gt C）、灌木林（0.024Gt C）、国外松林（0.015 Gt C）、经济林（0.010 Gt C）、针阔混交林（0.009 Gt C）和软阔林（0.002Gt C）。江西省森林植被碳密度呈现由南向北,由东向西逐渐递减的趋势,碳储量南部和中西部高于中东部和北部。碳储量地理分布依序为赣州市（0.053 Gt C）、吉安市（0.039Gt C）、上饶市（0.027Gt C）、抚州市（0.024Gt C）、宜春市（0.024Gt C）、九江市（0.019Gt C）、景德镇市（0.007Gt C）、萍乡市（0.006Gt C）、新余市（0.004Gt C）、鹰潭市（0.004Gt C）和南昌市（0.002Gt C）。3.树种、坡向、郁闭度和林分密度对碳密度的影响显著,坡位和年龄的影响不显著。随着年龄和土层深度的增加杉木林土壤碳密度逐渐降低。更多还原

【Abstract】 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 0.210^Gt 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.更多还原
