Study on the Relationships between Terrestrial Bryophytes and Environmental Factors in Yangjifeng Nature Reserve,China

A total of 106 species (including one variety) belonging to 56 genera and 34 families of terrestrial bryophytes were collected from 25 sampling quadrates in YangjifengNature Reserve,Jiangxi Province,China.Canonical Correspondence Analysis (CCA) determined the relationship between terrestrial bryophytes (38 species) and their environmental variables for the first time in this area.Results indicated that environmental factors influenced the distribution and biological diversity of bryophytes considerably.The main environmental variables were humidity and substructure,and the secondary variables included canopy density,shrub coverage,altitude,gradient,and human activities.
