Abstract:: Based on the 7th forest resource inventory data of Qinglong Manchu Autonomous County in 2005, the storage and density of carbon were calculated using the biomass expansion factor continuous function method and average-biomass computing method, the carbon content in the molecular formulas of various trees. Using the regression analysis method fitted the curve equation between carbon density and age, the carbon storage and density in 2020，2030 and 2050 were estimated with the curve equation by setting 2005 as the base year, and assuming that the area of forest stand remained stable and tress kept on growing, not considering the influence of reforestation, logging, death, and so on. As the estimation of forest vegetation carbon storage and carbon density, the estimated results had a certain error, but could reflect the general situation of the carbon storage. Results are as follows： The carbon storage of forest vegetation in Qinglong Manchu Autonomous County was 255.5×10⁴ t, the average carbon density was 10.73 t/hm². The forest vegetation carbon storage and density were higher in the northern and southeastern mountainous areas were low in the central river valley and hills areas with respect to spatial distribution. Forest vegetation in state-owned forest farms had relatively higher carbon density. The main body of forest vegetation carbon storage in Qinglong Manchu Autonomous County is Pinus tabulaeformis, shrubbery，Quercus mongolica, economic forest. The carbon storage was 1.815 7×10⁶ t，2.563 7×10⁶ t and 3.982 5×10⁶ t in 2020，2030 and 2050, respectively, in Qinglong Manchu Autonomous County.
