摘要
通过对南靖林场 1995年造林山地麻竹林竹株生物量测定 ,结果表明 3个年度麻竹竹秆生物量随竹秆高度的升高而呈明显减小的趋势 ,竹枝、竹叶和各构件总生物量随高度的升高呈“小、大、小”的变化 ;枝叶生物量比随竹高的升高而降低 ,竹蔸和竹根生物以 2年竹为最大 ,1年竹其次。 2个年度麻竹不同径阶各构件生物量随径阶的增大而逐渐增大 ,且 2年竹各构件生物量大于 1年竹。 2个年度麻竹竹秆和地上部分各构件总生物量预测方程拟合良好。
According to the measurements of biomass of bamboo in Nanjing State-owned Forestry Farm planted on mountain in 1995, the biomass of the stems of three ages tends to decrease with their height increase. Biomass of twig, leaf and other components above ground shows tend of small-large-small with the height increase. The ratio between twig and leaf is increasing with the height increase. The largest biomass of stem under ground and root is the two-years-old bamboo, and the next is the one-year-old bamboo. The biomass of all components of different D.B.H of the bamboo of two ages are increasing with D.B.H increase, and that of the two-years-old bamboo is larger than that of the one year-old bamboo. The forecast equation is of good fitness to the stem and the total biobass.
