| 摘 要： | 根据调查资料,利用生存分析理论,编制了静态生命表,分析了黄土高原马栏林区辽东栎种群的径级结构及存活曲线;同时应用谱分析方法分析了辽东栎种群数量动态变化的周期性。结果表明:辽东栎种群存活曲线的变化趋势更接近DeeveyⅡ型,死亡曲线在Ⅳ龄级处有一个小高峰;在辽东栎种群自然更新过程中存在周期性,但基本周期时间比较长,更新比较慢。总体上说,马栏林区辽东栎种群目前正处于一个稳定状态。

| Abstract: | Based on the investigative data of tree species Quercus liaotungensis(Q.wutaishanica) population in Malan forest region on the Loess Plateau,using the theory of survival analysis,the author constructed the static life table of Q.liaotungensis population,and analyzed its size-class structure and survival curve.At the same time,the periodicity of population dynamics of Q.liaotungensis was analyzed through spectral analysis.The results showed that the survival curve tended to be Deevey Ⅱ type,and there was one... |
