摘  要:
采用典型抽样,对秦岭西段小陇山林区天然秦岭冷杉群落进行调查,应用"空间代替时间"的方法编制秦岭冷杉种群的生命表,结果表明,秦岭冷杉种群在发育和演替过程中,存在2个死亡高峰,即由种子转化为幼树阶段出现第1个高峰,成年期出现第2个高峰,14龄级时大多数个体死亡。同时认为,秦岭冷杉天然更新困难,种群发育不良。

摘  要:
The invstigation was conducted on natural communities of Abies chensiensis in Xiaolongshan forest area of west section of Qinling,and the life table of communities was compiled using the method of spatial se-quence instead of time successional sequence.The result indicated that Abies chensiensis had two deaths peak during its development and succession.That is: One is the stage of seed conversation into young seedling,and the other is adult stage,and most of them died at the age of 14.It is regarded that Abies chensiensis had poor devel-opment and difficulties in natural regeneration.
