Abstract: 【Objective】 Forest carbon storage was estimated for Jiangxi Province based on forest resource inventory data from 1988 to 2011. Changes in carbon storage for different types of forests and the carbon sequestration potential of forest vegetation was estimated, providing a theoretical basis for the scientific management of forest resources.【Method】 Carbon storage, carbon density and carbon sequestration potential of the forest in Jiangxi Province were calculated based on forest inventory data by using the continuous function for biomass expansion factor(BEF)and average biomass. 【Result】 Results show that the carbon storage in Jiangxi Province increased from 1988 to 2011 by 81.38-188.52 Tg, with an average annual growth rate of 3.7%. However, forest carbon density in Jiangxi Province is still considerably lower than the national average. Significant differences were found among carbon densities of different forest origins and types. The carbon density of natural forest was higher than that of the artificial forest. The forest in Jiangxi Province has a large carbon sequestration potential that can reach 191.48 Tg through forestry growth and reforestation. 【Conclusion】 The forest area and carbon storage of Jiangxi Province show a trend of rapid growth; however, compared with the national average, its carbon density is relatively lower. The main reason is the forest in Jiangxi Province dominated by young forest. Which also indicates that the forest carbon sink potential of Jiangxi Province is large and has a large carbon sink function through afforestation, reforestation and forest growth.
