Bamboo (Phyllostachy pubescens) is an important forest resource in Southern China. As a result, bamboo plantations play a significant role not only in bamboo industry and economic trade, but also in carbon sink. The distribution of carbon content in various organs of bamboo forest in different ages is studied in different age bamboo forest in Taojiang County, Hunan Province. The results showed that the average carbon content of bamboo organs in different ages is between 389.334~534.051 g?kg-1, and content of carbon in different organs are different. The carbon content of each organ of aboveground parts of 1-year-old, 3-year-old, 5-year-old bamboo are: bamboo culms>bamboo leaves>bamboo branches, bamboo branches> bamboo culms>bamboo leaves, bamboo leaves>bamboo culms>bamboo branches, and the carbon contents of each organ of underground parts are: bamboo whips>lateral roots>bamboo stumps>fibrous roots, bamboo whips>bamboo stumps>fibrous roots>lateral roots, fibrous roots>bamboo stumps>bamboo whips>lateral roots, respectively. There is no significant difference in the carbon contents of organs among those different aged bamboo forests(P<0.05), and there is no obviously change with the growth of bamboo age.
