中文摘要:
      以贵州平坝县斑苦竹为试材料,对不同龄级斑苦竹生物量分配规律、构件生物量与调查因子的相关性进行了研究。结果表明:同一龄级斑苦竹各构件含水率不同,构件的含水率随竹龄的增大而下降。地上生物量与龄级相关,Ⅰ龄级的地上生物量较小,其他龄级的地上生物量无显著差异。构件生物量在各龄级间存在显著差异,秆构件生物量随龄级增大而增大,自Ⅱ龄级后趋于稳定。枝和叶构件生物量随龄级增大而增大。不同构件占地上生物量的比例不同,其中,秆构件所占比例最大,枝和叶构件的比例无显著差异。斑苦竹各构件生物量与胸径估测模型用幂函数的拟合效果最好。
英文摘要:
      Pleioblastus maculata in Pingba County, Guizhou Province as test materials, above-ground biomass allocation pattern at different age classes, the correlation of modular biomass and survey factors were studied. The results showed moisture content of each module was different at the same age class. Modular moisture content decreased with the increasing age of bamboo culm. The aboveground biomass was related to the age class culm, and there were no significant differences in Ⅱ~Ⅴage class culms, but the aboveground biomass of Ⅰ age-class was smaller. It was significantly different among modular biomass in different age classes, and the stem biomass increased with the increasing of age class, but kept being stable since Ⅱ age class. The biomass of branches and leaves also increased with age class. Different modular biomass had different proportion. The stem module accounted for the largest proportion. There was no significant difference between the proportion of branch and leaf. The modular biomass of P. maculata and DBH estimation model fit best with power function.
