　　摘要：利用立木蓄积量、森林面积及森林土壤碳储量等基本监测数据，对江西省森林生态系统的碳储量和碳汇及其经济价值进行了估算。结果表明：江西省森林生态系统碳储量为1 ×106t，×106 t，其经济价值分别为3 ， t/hm2。×106 t碳或1 ×106 t CO2，。同时还对江西省11个市的森林碳储量、碳汇及其经济价值进行了估算，得出了全省各市森林生态系统碳储量和空间分布特征以及各地的森林碳汇林地价格。

　　Abstract:On basic monitoring data of the volume of tree, forest area, forest soil carbon storage, etc, the carbon storage of forest ecosystems, carbon sinks and its economic value in Jiangxi Province are estimated. The results showed that, the carbon storage of forest ecosystem is 1 ×106t; the carbon sink capacity is ×106t / year; Respectively, its economic value is billion RMB and billion RMB. The average carbon density of forest ecosystems is t / hm2. The forest ecosystems is expected to increase carbon sequestration potential of × 106 t carbon sink or CO2 1 × 106 t absorption each year from 2010 to 2020 year, which creates billion RBM every year. While forest carbon stocks, carbon sinks and their economic value being estimated, the forest carbon stocks, the carbon spatial distribution characteristics and the value of forestland in 11 cities of Jiangxi Province are estimated.
　　Key words: forest ecosystem; forest carbon sinks; carbon density; economic value of carbon sinks
