| 摘 要： | 通过样地调查和数据分析,对大果青扦残存群落的地理分布、群落特性、种群年龄结构进行了系统研究。结果表明,大果青扦群落现仅岛屿化分布于秦岭山区及其余脉地区。群落中共包含种子植物51科97属126种,可划分成12个植物属的地理区系成分,其中温带分布型属占65.88%,大果青扦在整个群落中占绝对优势。根据群落中物种重要值聚类分析可以将大果青扦群落划分为4种基本类型。大果青扦种群年龄结构属于衰退型,极少见幼树幼苗,濒危情况严重,亟待保护。 |

| Abstract: | The geographic distribution,community structure and demographic characteristics of population were studied through field investigation and statistical analysis.It was only found scattered in small forest fragments in Qinling Mountain and the branch.Picea neoveitchii community includes 51 families,97genuses and 126 kind of spermatophyte,which could be divided into 12 kind of plant according to the geographical area.Among which,65.88% distribute in the temperate area.The Picea neoveitchii is in great strength... |
