摘　　要：为了揭示沙质海岸带天然植被中潺槁树种群生命过程,对福建东山岛沙质海岸带不同风水林的潺槁树群落进行调查和数据统计,通过编制种群生命表,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,分析了其种群的年龄结构及动态变化.结果表明:山只村潺槁树种群具8个龄级,黄山村具7个龄级,两者年龄结构皆呈反J分布型,而后姚村具6个龄级,不呈反J分布型,但三者都属于增长型种群;山只村和后姚村潺槁树种群存活曲线都属于Deevey-Ⅱ型,前者呈现2个死亡高峰,后者呈现3个死亡高峰,而黄山村属于Deevey-Ⅲ型,呈现2个死亡高峰;4个生存函数值(生存率、积累死亡率、死亡密度、危险率)均说明3片风水林潺槁树种群具有前期增长、后期稳定的特点.In order to reveal the life process of Litsea glutinosa population in natural vegetation of sandy coast, Litsea glutinosa communities on the coast of Dongshan island was investigated. The age structure and dynamic changes survival rate, death rate, were analyzed. The results of Litsea glutinosa population with the static life table, the curves of killing value, death density function, cumulative death and hazard rates showed that the age classes of Litsea glutinosa population in Shanzhi village and Hangshan village were 8 and 7, respectively. The age structure appeared to be inversed J shape. The age class of Litsea glutinosa population in Houyao village is 6, and the age structure did not appear to be inversed J shape. They were at the up-growth stage. The survival curves in Shanzhi and Houyao village belonged to Deevey-Ⅱ, and the former had 2 dead peaks, the latter 3. The survival curve in Hangshan village belonged to Deevey-Ⅲ, with 2 dead peaks. Four functions （survival rate, death rate, death density, hazard rate） all indicated that the population increased at the early stage,but kept stable at the late stage.
