摘要: <正>通过对鹅掌楸种群年龄结构、大小结构和静态生命表分析及比较,得出浙江省龙王山鹅掌楸种群结构属衰退型。相对而言,马峰庵样地种群结构衰退程度更重,仙人桥样地种群结构衰退程度较轻。因此,加强龙王山鹅掌楸种群的保护是当务之急。

Abstract: Liriodendron chinense(Hemsl.) Sarg.population at Mt.Longwang,Zhejiang,appears to be declined,by means of measurement and analysis in age-structure,size-structure,and static life-table.Local population at Mafengan seems to be more intensively declined than that at Xianrenqiao.It is suggested that strengthening conservation practice of these populations should be an emergency task.
