摘　　要：【目的】根据江西省森林资源清查数据,分别估算不同森林类型的生物量碳库及其变化,并估算森林植被的固碳潜力,为森林资源的科学管理提供理论依据。【方法】基于江西省1988—2011年森林资源清查统计数据,采用生物量换算因子连续函数法和平均生物量法,计算江西省森林植被的碳储量变化、碳密度及固碳潜力。【结果】1998—2011年江西省森林碳储量呈增长趋势,从81.38 Tg增长至188.52 Tg,年平均增长率达到3.7%;江西省森林碳密度远低于全国平均水平,不同起源和植被类型的碳密度有较大差异,天然林的碳密度比人工林的高;江西省森林植被碳汇潜力巨大,通过林业生长和再造林,固碳量可达191. 48 Tg。【结论】江西省森林面积及碳储量呈较快增长趋势,但与全国平均水平比较,碳密度仍处于较低水平,主要原因在于江西省森林以幼龄林为主,这也预示随着后续的植树造林和森林生长,江西省的森林碳汇潜力较大。【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.
