采用标准木调查法，对鲁西平原4种造林配置（株行距2m×3m、2m×4m、2m×5m和2m×6m）5年生杨树试验林的生长和地上生物量进行分析。结果表明：造林配置对5年生杨树单株胸径和地上生物量有显著影响（ P＜0．05），对单株树高影响不显著；单株胸径、树高、冠幅和单株地上生物量总体随造林株行距减小而减小；胸径、树高与树干、枝、叶生物量间均为正相关关系；利用方程y＝－0．4006x2＋16．671x－104．12可较好拟合单株地上生物量与单株胸径的关系。以获取单位面积最大地上生物量为目标，株行距2 m×3 m适用于鲁西平原杨树人工林造林。

A plot survey was conducted in a 5-year-old Populous plantation with four planting spacing (spacing of 2 m×3 m, 2 m× 4 m, 2 m×5 m, and 2 m×6 m) to study the influence of initial spacing on the growth and biomass accumulation .Initial planting spacing had significant effects on diameter at breast height ( DBH) and single tree volume ( P<0.05) , but had no significant effects on single tree height and stand biomass .With the increase of planting density , single tree DBH , tree vol-ume, crown and individual above-ground biomass were decreased , but stand biomass was increased .DBH and tree height were positively correlated to stem , branch and leaf biomass .The equation of y=-0.400 6x2+16.671x-104.12 was applica-ble to the relationship between individual above-ground biomass and DBH .In terms of a combination of stand level biomass accumulation, we suggested a planting density of 2 m×3 m for plantation in western plain area of Shangdong Province .
