Abstract Based on the data of 3rd (1992—1997) and 5th (2002—2007) forest resources inventory in Yunnan Province，forest carbon storage，carbon density and its dynamic change in Yunnan Province were analyzed by adopting the biomass expansion factor continuous function. The results were as followed: in recent 10 years the forest carbon storage increased from 679.10Tg in 1997 to 884.11Tg in 2007, and the annual growth rate was 2.67%. The carbon density of arboreal forest increased from 46.80Mg/hm2 in 1997 to 50.58Mg/hm2 in 2007, higher than the national average level of carbon density. The forest was mainly young, middle-aged forest in Yunnan Province, its area accounted for more than 65% of the total forests，which showed that forest vegetation in Yunnan Province had great potential to stock carbon.
