| 摘 要： | 以种群生命表及生存分析理论为基础，编制丝栗栲种群静态生命表，绘制存活曲线，死亡率曲线，亏损度曲线，死亡密度函数曲线。积累死亡函数曲线和危险率函数曲线，分析种群生命过程。结果表明，丝栗栲有2个死亡高峰，存活曲线趋于Deevey-Ⅱ型。并应用谱分析方法研究丝栗栲种群动态，结果表明，在丝栗栲种群自然更新过程中存在着明显的周期性。

| Abstract: | Based on the life table of population and the theory of survival analysis, the authors worked out a static life table of Castanopsis fargesii, drew the curves of mortality rate, survival rate, killing value, survival rate function, mortality density function, cumulative mortality rate and hazard rate function, and analyzed the life process of population. The results showed that the population had two peaks of mortality, and the survival curve of the population trended to the type of Deevey II. Then spectral analysis of the population dynamics of C. fargesii was made, which showed that there was a marked regularity of periodic fluctuation in the process of natural regeneration of C. fargesii .
