摘要: 在3种天然次生林类型中,以刺五加的无性系小株为统计单位,编制该种群的生命表,分析其种群动态。结果表明,刺五加种群有2个死亡率高峰,在不同的森林群落中其死亡强度有较明显差异。种群的总亏损度不同,这些都与群落生境有关。该种群的存活曲线趋近于DeeveyⅢ型。

关键词: 种群统计, 刺五加, 生命表, 亏损度

Abstract: The life tables of Acan thopanax senticosus population under three natural secondary forests are compiled with its ramet as statistic unit,and the population dynamics are analysed. The results show that the population has two peaks of mortality, and its death intensity has signifcant difference in different forest communities. The total killing power is different, too. All these are related to the habitats of communities. The survival curves of the population approximate to the Deevey Ⅲ.

Key words: Population statistics, Acanthopanax senticosus, Life table, Killing power
