Species diversity of floor bryophyte communities in Bogda Mountains,Xinjiang

Abstract

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.
