Abstract: The carbon content distribution and storage in three of types forest have been investigated in Xiashu forest farm.The results showed: (1)The carbon content varied with different tree species and different organs of the same tree species.The carbon content in the Chinese fir, Loblolly pine and Oriental oak trees were 51.0%,54.5% and 49.9% respectively.(2)The accumulation of carbon in Loblolly pine, Chinese fir, Oriental oak stands were 5.79t·ha^-1·yr^-1 ,2.46t·ha^-1·yr^-1 and 2.46t·ha^-1·yr^-1 respectively, (3) The carbon storage in the forest ecosytems (including 0～80cm soil layer) was 163.96t·ha^-1 in Loblolly pine stands, 174.62t·ha^-1 in Oriental oak stands and 117.68t·ha^-1 in Chinese fie stands.About 32.9%～43.3% of the total carbon storage was in the 0～80cm soil layer, while about 50%～60% of the carbon storage of the 0～80cm soil layer was in the 0～20cm soil layer. (4)In the three forest ecosystems, about 50% of the total carbon storage was in the stemwoods. Therefore, the carbon oxides released from the harvest of the forest would be very little if the forest regenereted in time and the fellings were not cleanly burned after the harvest.
