Study on Bryophyte Species Diversity in Different Landscapes in Qilian Mountain

In this paper, a sampling survey was conducted on the bryophytes in different landscapes of Qilian Mountain, with species composition, similarity, and species diversity index investigated. Nineteen families, 34 genera, and 48 species of bryophytes were found. There were six dominant families, including 19 genera and 31 species, accounting for 55.88% of total genera and 65.58% of total species, respectively. The species similarity between coniferous forest and the alpine scrub belt was the highest (0.5357), while that between riparian forest and the alpine meadow belt was the lowest (0). Results showed that the bryoflora of Qilian Mountain was rich and complex. Although the species diversity index of the alpine scrub belt was the highest, the bryophyte community in the coniferous forest belt had the richest species diversity, indicating it was a key area for bryophyte species diversity conservation in Qilian Mountain.
