Abstract: Based on the data of the Continuous Forest Inventories(CFI),Biomass Expansion Factor(BEF) and the conversion model between biomass and carbon storage were used to estimate and analyze the biomass and carbon storage of different altitudes,age classes,canopy density,stand density and diameter classes and their variations.The results show that:1) the biomass and carbon storage of Pinus yunnanensis showed increase at first and then decrease with the increase of altitude.The 1800-2400 meters was the most suitable altitude range for Pinus yunnanensis growth.2) with the increase of age classes,it showed increase at first and then decrease.The highest value of sample biomass and carbon storage appeared in the middle-age forest.3) it showed increase at first and then decrease with the increasing of canopy density,the highest value appeared in the middle canopy density.4) with the increase of stand density,it showed increase at first and then decrease.The highest value appeared in Ⅱ stand density.5) with the increase of the diameter,it showed increase at first and then decrease.The maximum value appeared in the middle-diameter group.
