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
