阿帕斯立竹现存地上生物量及其构件因子关系研究

Present Aboveground Biomass and Relationship among Component Factors of Gigantochloa apus

对1~3年生阿帕斯立竹现存地上生物量和含水率进行了调查,结果表明:1~3年生立竹秆与竹枝含水率差异明显,随着竹龄的增大,含水率逐渐下降,而各年龄立竹叶含水率差异不大;地上生物量分配1年生立竹秆所占比重显著高于其他年份;立竹全高、胸径构件因子与地上各器官生物量之间相关显著,利用幂函数模型进行立竹胸径与各器官生物量回归分析,竹秆以及地上总生物量模型拟合程度较好,可用于该竹种生物量的估算。

This paper investigated the aboveground biomass and water content of 1-3 year-old Gigantochloa apus stands.The results indicated that water content of culm and branch obviously declined with increasing age.However,there were no significant difference in leaves.The rate of culm biomass of 1-year-old bamboo stands is larger than others.Both the full height and DBH of bamboo culm showed significant positive correlation to every component biomass,and the full height can be used as the tributary factor of DBH.Th...
