摘　　要：对浙江省平阳县大木竹及吊丝单竹1年生、3年生和5年生样竹的不同器官和不同生长部位的干质量热值进行研究。结果表明:1)大木竹、吊丝单竹各个器官的干质量热值存在较大差异,2个竹种地上部分均为竹秆>竹枝>竹叶,地下部分细根的干质量热值最小;2)大木竹、吊丝单竹各器官不同生长部位的平均干质量热值无显著差异,表明热值与植物器官生长部位没有显著关系;3)大木竹、吊丝单竹不同生长年龄竹株的各器官平均干质量热值差异不显著;4)大木竹与吊丝单竹相比较,秆、枝、叶、蔸、细根等各器官的干质量热值均是大木竹高于吊丝单竹。Gross caloric values（ GCV） of different organs and different growth zone of 1-year-old, 3-year-old and 5-year-old of Bambusa wenchouensis and Dendrocalamopsis vario-striata were studied in Pingyang County, Zhejiang Province. The results indicated that there was a disparity of GCV among different organs of Bambusa wenchouensis and Dendrocalamopsis vario-striata. GCV of above ground parts for the two species showed the same trend, as follows ： eulm 〉 branch 〉 leaf, root is the minimum. The mean GCV of Bambusa wenchouensis and Dendrocalamopsis vario-striata for each organ in different growth zone had no significant difference, implying little relationship between the growth zone and GCV. The mean GCV of each organ of Bambusa wenchouensis and Dendrocalamopsis vario-striata for different ages had no significant difference. As to different species, GCV of each organ of Bambusa wenchouensis was higher than that of Dendrocalamopsis vario-striata.
