| 摘 要： | 根据野外调查资料编制南方红豆杉种群的特定时间生命表,利用存活曲线、致死力曲线、植物种群结构动态量化分析方法等来综合分析种群的动态趋势,同时引入4个生存分析函数进行种群的生存分析.结果表明:南方红豆杉为稳定型种群,但种群早期存活数随龄级急剧下降,只有16%的幼苗能进入第2龄级,而后期存活值波动不大,说明幼苗成长为幼树的过程中要经过严格的环境筛选.分析认为,南于南方红豆杉幼苗竞争能力弱,在群落中处于被动适应的地位,导致其较高的死亡率,降低了其对后期各龄级的补充能力,同时人为干扰和破坏加重了这种趋势,从而导致其濒危. |

| Abstract: | Based on the data of field investigation in Anhui Province,the static state life table of Taxus chinensis var.mairei was formulated and analyzed.The survival curve,killing power curve and method of quantitative analysis for plant population structural dynamics were employed for analysis of the dynamic and fluctuation of its population,and the survival situation was estimated by four survival function index.The results were as follows:(1) The survival curve of the population belonged to Deevey II,suggesting ... |
