摘要：为更好地评估我国森林植被乔木层碳汇功能提供更准确和可靠的基础数据。利用江西省森林资源二类清查资料,运用材积源生物量法对江西省森林植被乔木层的碳储量和碳密度进行了研究。森林植被乔木层碳密度的特征为:全省不同森林植被乔木层类型碳密度由大到小依次为硬阔林、针阔混交林、毛竹林、国外松林、杉木林、软阔林、灌木林、马尾松林和经济林,且乔木层碳密度随着林龄的增加而增大,随其人口密度的增加而降低;森林植被乔木层碳储量的分配规律为:不同森林植被类型依次为杉木林、硬阔林、马尾松林、毛竹林、灌木林、国外松林、经济林、针阔混交林、软阔林,从森林类型分布看,除杉木和国外松林外,其它森林类型天然林的比例远大于人工林;从地理分布看,除南昌、萍乡、新余三市外,其余各市均是天然林远比人工林要多,全省不同年龄森林植被由大到小依次为,中龄林、幼龄林、近熟林、成熟林、过熟林,全省南部和中西部要高于中东部和北部。江西省森林植被乔木层的总碳储量0.210 Gt C,占全国森林总碳储量的5.66%。
In order to provide exact and credible data for evaluating carbon sink of tree stratum in forests in China,the forest resources second-class inventory materials and volume-biomass method are used to research the carbon storage and density of tree stratum in forest in Jiangxi. The characters of its carbon density are as follows：the carbon density of different forests from large to small are： hardwood forests, mixed coniferous and broad leaf forests, pubescens forests, exotic pine forests, fir forests, softwood forests, shrubbery, masson pine forests and economic forests. Its carbon density becomes larger with its age but becomes smaller with its population density. The distribution rule of its carbon storage is as follows the carbon storage of different forests from large to small are： fir forests, hardwood forests, masson pine forests, pubescens forests, shrubbery, exotic pine forests, economic forests, mixed coniferous and broad leaf forests and softwood forests. For different forests types, except fir and exotic pine forests, carbon storage of natural forests are all larger than plantations, for different cities in Jiangxi, except Nanchang, of natural forests are larger than plantations too.The carbon Pingxiang and Xinyu, the carbon storage storage of different ages are half-matureforest〉young growth forest〉premature forest〉mature forest〉postmature forest. The carbon storage of its southern part and midwest is larger than that of its east central and northern part. The total carbon storage of tree stratum in the forest in Jiangxi is 0.210 Gt C and it is taken up 5.66 percent of the total of China.
