摘要/Abstract

摘要： 资源冷杉是极度濒危的我国特有植物,其中湖南省炎陵县大院资源冷杉种群是最大的种群。本研究对大院4个自然分布的资源冷杉种群大小进行统计,分析大小级结构,编制静态生命表,绘制存活曲线。结果表明,自然分布的高1 m以上个体总数为477株。幼苗阶段死亡率很高。中牛石种群在大小级结构和种群规模上均处于衰退状态;香菇棚在大小级结构上较稳定,但种群规模减少;鸡麻捷和和平坳种群在大小级结构和种群规模上均处于稳定状态。

关键词: 资源冷杉, 大院种群, 大小级结构, 种群稳定性

Abstract: Abies ziyuanensis is a critically endangered conifer species endemically in China and the population in Dayuan,Yanling county.Hunan province is recognized as the largest one.Four natural A.ziyuanensis population were surveyed and the size structure.Life table and survival curve were analyzed.The result shows that there are 477 individuals of ≥1 m in height in the four population sites.The mortality is high at the seedling stage.The number of individuals decreases greatly in Zhongjiushi population along with the size grade indicating an obviously declining tendency.However,the size structure is stable in Xianggupeng population though the size scale is declining.Both size structure and scale are stable in Hepingao and Jimajie populations.

Key words: Abies ziyuanensis, population in Dayuan, size structure, population stability
