| 摘 要： | 本文应用生命表对多年生木本植物蒙古栎（Quercus mongolica）种群及其更新层中幼苗、幼树的年龄结构进行了较为详细的研究。从中能提供更多的有关种群年龄结构和各年龄阶段特定的存活率、死亡率、致死原因等生物学和生态学信息,揭示了环境筛对蒙古栎种群在时间上的作用规律,表明了生命表是对植物种群年龄结构分析的有效途径。

| Abstract: | The age structures of mongolian oak population and the seedlings and saplings in the understory are analysed in detail by applying life-table, from which more biological and ecological information on age structures, specific-age survival rate and mortality rate and its causes can be obtained. The effect of environmental sieve on mongolian oak population in time is also displayed. Therefore, it is proved that lif-table is an useful tool for analysing age structure of plant population. |
