摘　　要：依据油松林面积分布、林分生物量、地表枯落物、林下土壤有机质含量，估计中国油松林总储碳量约为２．８４７８×１０８ｔ，土壤有机碳占总储碳量的６５％。Based on the data of biomass,litter and soil organic matter,the carbon content inChinese pine(Pinus tabulaeformis Carr)forests was estimated as follow total forest area2061 400 hm￣2,total timber volume 5 509 × 10￣4 m￣3,above ground biomass C 6 120 ×10￣4 t,ground litter C 2 940×10￣4 t,rcot biomass C 778×10￣4 t,soil organic C 18 640×10￣4 t(depth:0～130 cm),total carbon 28 478×10￣4 t.The soil contains approximately 65%of the total carbonthat stored in Chinese pine forests. The carbon density is about l38t/hm￣2,in which,the soil or-ganic carbon is 90t/hm￣2.
