摘要: 以种群生命表及生存分析理论为基础,编制珍稀濒危植物长苞铁杉种群生命表,绘制死亡密度函数曲线、危险率函数曲线及生存曲线,分析种群动态趋势.结果表明,长苞铁杉种群有2个死亡高峰,存活曲线趋于Deevey-Ⅱ型.

Abstract: Tsuga longibracteata is a rare and endangered tree species in China.Based on the life table of population and the theory of survival analysis,the authors worked out the life table of Tsuga longibracteata population drew the curves of mortality density function,hazard rate function and survival,and analyzed the population dynamics.The results show that the population had two peaks of mortality,and the survival curve of the population trended to the type of Deevey Ⅱ.
