摘　　要：应用湿烧法对河南省10个主要造林树种不同器官的含碳率进行了测定、分析。结果表明,各组分含碳率为35.5%～47.6%,泡桐枝的含碳率最低,为35.5%,毛白杨根的含碳率最高,为47.6%;将10个树种的含碳率进行聚类分析,含碳率较高的树种是国槐、旱柳、椿树、楝树、法桐,可以作为河南省碳汇造林的优势树种。The carbon content rates of 10 major afforestation tree species in different organs in Henan province were measured. The results showed that the carbon content rate of each compo- nent was between 35.5%and 47.6% ,with the branch of paulownia being the lowest（35.5%）. The highest carbon rate 47.6% was found in the root of Maobaiyang. Cluster analysis was con- ducted with the 10 species using carbon rate data, showing that Sophora japonica, Salix matsu- dana, Toorasinensis roem ,Melia azedarach , and Platanus orientalis had higher carbon rate. The five species can be used as carbon afforestation tree species of advantage in Henan province.
