Abstract:

Based on the data about Pinus taiwanensis population and the theory of survival analysis and spectral analysis,the static life table,the curves of survival,mortality rate,killing power and hazard rate are drown in this paper.At the same time,the authors analyzed the population dynamics by spectral analysis method.The results showed that the curve of survival generally trend to the DeeveyⅡ—Ⅲ,and there was two peaks of mortality.Their death intensity and the time when they have mortality peaks had significant difference in different areas.The results from spectral analysis showed that Pinus taiwanensis in different areas had different growth periods,too.All these were related to the difference of geographical environment,climate and so on.

Key words: Population statistics, Life table, Survival analysis, Spectral analysis, Pinus taiwanensis
