Abstract: Based on the sixth forest inventory data of Taihe County,Jiangxi Province,this paper analyzed the curve relations between the carbon densities and ages of major forest types by using Logistic equation,and estimated the total amounts and change trends of the biomass and carbon storage of forest vegetation from 1985 to 2003 by the method of biomass expansion factor. The carbon storage in 2020 and 2030 was estimated by setting 2003 as the baseline year and assuming that the area of forest vegetation remained stable and without consideration of forest rotation. In 2003,the total forest area of Taihe County was 15.74×104 hm2,the total biomass was 6.71 Tg,the vegetation carbon storage was 4.14 Tg C,and the average carbon density was 26.31 t C·hm-2. In 1985,1994,2003,2020,and 2030,the forest carbon storage was 1.06,2.83,4.14,5.65,and 6.35 Tg C,respectively. The carbon density of the forest vegetation in Taihe County decreased from the eastern and western regions to the central. Artificial afforestation contributed significantly to the increase of forest stand area,and consequently,to the improvement of forest carbon sequestration capacity.
