摘　　要：毛竹(Phyllostachy pubescens)是我国南方重要的森林资源,它不仅在我国竹产业发展中占有重要的地位,而且在固碳增汇中起着更为重要的作用.本研究以湖南桃江县不同年龄毛竹人工林为研究对象,探讨不同年龄毛竹林各器官碳含量分布特征.研究结果表明:毛竹林不同年龄竹林各器官碳素平均含量在389.334~534.051 g·kg-1之间,且器官不同,碳含量不同.1年生,3年生,5年生毛竹林地上部分各器官碳含量分别为:竹竿>竹叶>竹枝、竹枝>竹竿>竹叶、竹叶>竹竿>竹枝;地下部分各器官碳含量分别为:竹鞭>侧根>竹蔸>须根、竹鞭>竹蔸>须根>侧根、须根>竹蔸>竹鞭>侧根.但各龄级器官碳含量差异不显著(P>0.05),并随着毛竹年龄的增长,其器官碳含量无明显的变化规律.Bamboo （PhyUostachy 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.
