摘  要:
为了更好的了解福建武夷山野生早樱种群结构与动态,运用静态生命表、种群年龄结构图、存活率曲线、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对该种群生命过程进行了分析。结果表明:野生早樱种群的死亡高峰出现在幼龄期,并在龄级Ⅶ再次出现一死亡小高峰;存活曲线趋于DeeveyⅢ型。种群年龄结构呈现出纺锤形,幼老年种群株数严重偏少,种群整体呈衰退状态。光是限制该种群增长的关键性因子,建议适度干扰或开辟林窗有利于野生早樱的自然繁衍。

摘  要:
In order to realize the structure and dynamics of Cerasus subhirtella var.ascendens population in Wuyi Mountain of Fujian Province,static life time,curves of morality,survival rate,killing value,survival rate function,morality density function,cumulative mortality rate and hazard rate function are utilized to analyze the life process of the population.The results show that the peak of morality occur at the young age class and a small peak at the seventh age class;the survival curve of the population trends to the type of Deevey Ⅲ.The population age structure presents the spindle,which means the number of seedlings and old trees is very low,and the whole population of Cerasus subhirtella var.ascendens is declining.Light is the critical factor to limit the population increasing,so we suggest that moderate disturbance or artificial forest gaps be helpful to the breeding of it.
