中文摘要：

对不同生境下刺五加种群的年龄级结构、高度级结构和径级结构进行了研究。结果表明：不同样地刺五加种群的年龄级结构、高度级结构和径级结构具有一定的差异。蒙古栎林中刺五加种群的年龄级结构比较稳定,针阔混交林和次生杂木林刺五加种群的年龄级结构处于不稳定状态。刺五加种群的高度级和径级结构分布规律与年龄级分布相似,这与刺五加种群所处的群落生境密切相关。

英文摘要：

The structures of age, height and diameter class of Acanthopanax senticosus were studied in different ecological habitats. The result showed that the structures of age, height and diameter class differed significantly in different plots. The age class structure of Acanthopanax senticosus population was stable in the Quercus mongolica forest, but they were unstable in the theropencedrymion and secondary forest. The height class and diameter class were similar to the age class, which had close relation with community condition.
