中文摘要
对马来甜龙竹1年生、2年生、3年生3个龄级立竹不同径级地上部分各构件含水率和生物量进行测定分析,结果表明:1年生竹地上竹秆、枝条和叶片含水率明显高于2年生和3年生竹;同龄竹比较,竹秆含水率最高;竹秆生物量占地上部分生物量比例随竹龄增加而降低;马来甜龙竹地上各部分生物量之间呈极显著相关关系。经生长模型分析结果表明,可利用胸径和秆高估算立竹地上各部分生物量及总生物量。

英文摘要
This paper investigated and analyzed the aboveground biomass and moisture content of 1-, 2-, and 3-year-old Dendrocalamus asper. The results indicated that the water content of culm, branch and leaf of 1-year-old D. asper are signifcantly higher than those of 2-and 3-year-old ones; the water content of culm is higher than those in other parts when bamboo is at the same age; with the age increasing, the proportion that the culm biomass occupies the aboveground biomass decreases; and the aboveground biomass of different organs of D. asper is extremely signifcantly correlated with each other. The analysis results through allometric model showed that DBH and culm height can be used to estimate the biomass of aboveground parts and total biomass of D. asper.
