Abstract: There are 469 species of bryophytes (including 32 taxa under species) belonging to 179 genera and 65 families in Mt . Changhai. The species richness ranged from the highest to the lowest as saxicolous bryophytes , saprophytic bryophytes , epiphytic bryophytes , soil and humus bryophytes and peat , marsh and water bryophytes. For soil and humus bryophytes , the species richness is highest in dark conifer forest ,Shannon index is highest in L arix olgensis- bogs and dark conifer forest . The species richness and Shannon index for saprophytic bryophytes are highest in the dark conifer forest , and those for epiphtic bryophytes are highest in both the dark conifer forest and the transitive forest between Pinus koraiensis borad-leaved mixed forest and dark conifer forest . Qualitative analyses showed that altitude , canopy density , soil acidity , soil water content and richness of rotten wood in the forest could be the important environmental factors influencing the diversity of bryophytes. Among them , the humidity and canopy density rank the first .
