摘要
通过对江西省14个毛竹主产县的34个样地毛竹立竹度、平均胸径、林分高度和立竹整齐度等4个林分因子的调查资料进行分析,结果表明:4个竹林结构因子在垂直地带性变化上均有明显的变化规律,其中立竹度总体随海拔升高而增大,林分胸径、高度和整齐度则与之相反,即随海拔的升高而减小。
4 factors of stands on 34 sample plots such as density of bamboo plantation, average DBH, height and regularity were analyzed in 14 chief bamboo-producing counties of Jiangxi Province for Phyllostachys pubescens Mazel. of which,the results showed these 4 factors had obvious law of change with vertical zonality on the whole, of which, The density of bamboo plantation increased with the rise of altitude, whereas DBH, height and regularity decreased.
