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.
运用物种相似性系数和物种多样性指数，对新疆博格达山地藓类植物群落的物种多样性特征进行了研究。结果表明，博格达山苔藓植物区系具有丰富性和复杂性的特点。有186种地生种类（包括种下分类群），隶属于32科73属。山地荒漠与山地草原带之间的物种相似性最高（0.6809），而山地森林与高山垫状植被带之间的物种相似性最低（0.1342）。山地森林中的藓类植物群落是地生藓类植物群落中的优势群落。山地森林中的藓类植物群落物种多样性最丰富，山地森林是博格达山地区藓类植物多样性的分布中心和藓类植物多样性保护的关键区域。
