摘要
根据 3个地区的黄山松种群的调查材料 ,利用生存分析理论 ,编制静态生命表 ,绘制各个地区的生存曲线、死亡率曲线、亏损度曲线及危险率函数曲线 ,同时应用谱分析方法分析种群数量的动态变化。结果表明 ,黄山松种群的存活曲线整体上趋于DeeveyⅡ～Ⅲ型之间 ;死亡率曲线有两个高峰 ;不同地区的种群其死亡强度和死亡高峰出现的时间格局有明显的差异 ;谱分析表明不同地区的黄山松种群生长周期不同。以上结果与各地区所处的地理环境、气候条件等因素的不同有关。
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.
