以辽东山区蒙古栎(Quercus mongolica)天然林为研究对象,在冰砬山森林生态站研究了不同林龄蒙古栎单木碳储量动态及其林分碳密度的差异,估算了蒙古栎天然林年净固碳量。结果显示：蒙古栎单木碳储量与林龄和胸径密切正相关,与树高相关性较差；林分碳密度随着林龄的增加而增大,总体上林分各个器官碳密度为干>根>枝>叶；蒙古栎天然林乔木年净固碳量在3.83~5.48 t hm-2 a-1,折合 CO2量14.05~20.1 t hm-2 a-1,在中龄时达到峰值,固碳能力最强,而后随着林龄增加而降低。

Taking Quercus mongolica plantation which distribute widely in Mountainous area in eastern Liaoning province as research obj ect,the differences of dynamics of carbon storage for individual tree with different forest ages in Binglashan Forest Eco-station and carbon density of stand were studied;the net annual carbon sequestration was estimated.Result shows that the carbon storage of individual tree for Quercus mongolica which was positively corre-lated with the forest age and DBH had poor correlation with the tree height.The carbon density of stand for Quercus mongolica forest increased with the increase of the forest age.Overall,the descending order of the carbon density for each part is stem> root> branch> leaf.The annual net carbon accumulation of Quercus mongolica plantation ranged from 3.83 t hm-2 a-1 to 5.48 t hm-2 a-1;the equivalent amount of CO2 is from 14.05 t hm-2 a-1 to 20.1 t hm-2 a-1 .The carbon sequestration in the middle age are the most strongest ,being the peak value,and then de-crease with the increase of the forest age.
