By using forest resources inventory data and field investigation data, this paper studied the carbon storage, density, and distribution characteristics in forest ecosystems in Jilin Province of Northeast China. The total carbon storage in the forest ecosystems was 1827.293 Tg C, and the carbon storages in arbor layer, shrub-grass layer, litter layer, and soil were 439.152 Tg C, 5.195 Tg C, 45.600 Tg C, and 1330.466 Tg C, accounting for 24.1%, 0.3%, 2.5%, and 73.1% of the total, respectively. The carbon density in the forest ecosystems was 225.304 Mg C x hm(-2), with 54.352 Mg C x hm(-2) in arbor layer, 0.643 Mg C x hm(-2) in shrub-grass layer, 5.644 Mg C x hm(-2) in litter layer, and 164.666 Mg C x hm(-2) in soil. Different types of the forest ecosystems had a carbon storage varied from 9.357 Tg C to 959.716 Tg C and a carbon density ranged from 180.648 Mg C * hm(-2) to 254.627 Mg C x hm(-2), with the highest values in soil and the lowest values in shrub-grass layer. Overall, the carbon storage and density in the forest ecosystems were greater in eastern mountainous area than in central and western plains. In the Province, middle-aged forests had a greater proportion than the forests in other age classes, and thereby, a proper management of the present forests could increase the carbon sequestration of the forest ecosystems.
利用森林资源清查数据和实地调查数据，本文研究了中国东北吉林省森林生态系统的碳储量、碳密度及分布特征。森林生态系统的总碳储量为1827.293太克碳，乔木层、灌草层、凋落物层和土壤的碳储量分别为439.152太克碳、5.195太克碳、45.600太克碳和1330.466太克碳，分别占总量的24.1%、0.3%、2.5%和73.1%。森林生态系统的碳密度为225.304兆克碳每公顷，其中乔木层为54.352兆克碳每公顷，灌草层为0.643兆克碳每公顷，凋落物层为5.644兆克碳每公顷，土壤为164.666兆克碳每公顷。不同类型的森林生态系统碳储量在9.357太克碳至959.716太克碳之间，碳密度在180.648兆克碳每公顷至254.627兆克碳每公顷之间，土壤中的碳储量和碳密度最高，灌草层最低。总体而言，东部山区森林生态系统的碳储量和碳密度高于中部和西部平原。在该省，中龄林的比例高于其他龄级的森林，因此，对现有森林进行适当管理可以增加森林生态系统的碳固存。
