摘要/Abstract

摘要： 采用相似性系数和物种多样性指数对新疆博格达山地面生苔藓植物的物种多样性进行了研究.结果表明,博格达山地区苔藓植物区系具有丰富性和复杂性的特点,共有地面生苔藓植物32科73属186种(含变种、变型);山地荒漠带和山地草原带苔藓植物物种相似性最高,为0.6809,山地森林带和高山垫状植被带相似性最低,仅为0.1342;山地森林带苔藓植物在整个博格达山地面生苔藓植物群落中占据优势地位;山地森林带苔藓植物物种多样性最为丰富,为该山地苔藓植物多样性的分布中心,是苔藓植物多样性保护的关键地区.

关键词: 博格达山, 苔藓植物, 物种多样性, 相似性系数

Abstract: By means of species similarity coefficient and species diversity index,the characteristics of species diversity of floor bryophyte communities in Bogda Mountain,Xinjiang were studied. The results showed that the bryoflora of Bogda Mountain had the characteristics of richness and complexion. There were 186 floor species (including infraspecies taxa) belonging to 73 genera of 32 families. The species similarity between mountain desert and mountain grassland belt was the highest (0.6809),while that between mountain forest and alpine cushion belt was the lowest (0.1342). The bryophyte community in mountain forest was the ominant one among the floor bryophyte communities. The bryophyte community in mountain forest had the richest species diversity,and the mountain forest was the distribution center of bryophyte diversity and the key area for bryophyte diversity conservation in Bogda Mountain area.

Key words: Bogda Mountain, Bryophyte, Species diversity, Similarity coefficient
