摘　　要：采用胸径、树高、生物量及材积计测大小比数对顺昌县埔上国有林场木荷人工林空间结构进行分析,结果表明:木荷人工纯林的胸径、材积、生物量大小比数基本呈以中庸级为轴的近似正态抛物线状分布,而树高大小比数则呈右偏的抛物线状分布.各大小比数之间,胸径和生物量大小比数的相关性达到极显著水平,而树高大小比数与胸径(包括生物量)大小比数相关性不明显,而群落平均大小比数基本相近,表明木荷人工纯林群落胸径、树高以及生物量等的分化程度基本一致.The spatial structure of the pure Schima superba plantation in Pushang National Forest Farm of Shunchang County, Fujian Province was studied by means of neighborhood comparison analysis by taking DBH, tree height, biomass and standing volume as variables. The results showed that the neighborhood comparisons measured by DBH, standing volume and biomass showed normal parabola distribution with moderate symmetrical axle, while the neighborhood comparison measured by tree height appeared to be parabola distribution with fight deflecion. The correlation of neighborhood comparisons measured by DBH and biomass was up to extremely significant level, and the correlation of neighborhood comparisons measured by the tree height and DBH （including the biomass） was not significant. The average neighborhood comparison of community was basically equal, which showed that the degree of differentiation measured by DBH, tree height and biomass was basically consistent in the pure Schima superba plantation community.
