摘要
云冷杉群落是梅里雪山乃至喜玛拉雅-横断山地区的主要的植被类型.应用植物群落学的方法,在梅里雪山(东坡)选取10m×10m云冷杉群落样方60个,进行植物区系分析.研究表明在总计6000m2的样地内,共有植物64科,133属,223种.属的区系分析,科、属、种的分布分析及历史成分分析都表明:①梅里雪山云冷杉群落的区系基本上是温带性质的,温带成分属是总属数的71.40%.②梅里雪山云冷杉群落发展过程中受的分布区气候———亚热带气候的强烈的影响.③梅里雪山云冷杉群落起源古老,而且区系成分的一个重要来源是北极-第三纪植物区系成分.④梅里雪山云冷杉群落的植物区系与古地中海植物区系可能有联系,但尚需进一步的研究和讨论.
PiceaAbies Community is one of the typical forests of Meili snow mountain.In this paper,the floral analysis was made in 60 releves whose square in all is 6?000?m2.the result shows there are 223 species belonging to 64 families, 133 genera.Meanwhile,the analysis indicates the following.First the PiceaAbiea Community type has a characteristic of Temperate Zone, the Temperate Zone elements are 71.40% of the whole genera.Addition the PiceaAbies Community is impacted strongly by the climate where it di...
