摘要：选择我国新疆境内天山山脉从西到东处于不同经度位置5个地区(昭苏、巩留、乌苏、乌鲁木齐和哈密)的天山云杉林进行垂直样带调查,采用静态生命表法,分析5个地区天山云杉种群的存活曲线和死亡率曲线,为天山云杉种群数量统计和生态保护提供依据.结果表明:其存活曲线为DeeveyⅡ型,表明天山云杉种群处于动态稳定状态;5个地区天山云杉种群均有两个死亡率曲线高峰,死亡高峰主要出现在幼年时期、近成熟前期、成年阶段和老年期.种群的死亡强度和死亡高峰在时间格局上各地区有明显的差异.
Five vertical transects were investigated on the population dynamics of Picea schrenkiana var.tianschanica to lay a foundation for the population statistics and ecological protection.The transects were located from west to east along the Tianshan Mountains in Zhaosu,Gongliu,Wusu,Urumqi,and Hami of Xinjiang,China,respectively.The population static life tables were made,and the population curves of survivorship and mortality rate were formulated and drawn based on the data from 91 plots.The results showed that the survival curve of the populations could be generally summarized as the type of DeeveyⅡ,suggesting stable population dynamics.There were two mortality peaks for each of the populations in the five sites.The mortality peaks could be for young,fore-adult,adult and old-age groups but varied significantly among the different sites.Fig 2,Tab 6,Ref 31
