Abstract:The diversities of earth- and rock-type bryophytes in Baili Azalea National Forest Park, Guizhou Province were studied. The results showed that there were 57 species bryophytes, belonging to 34 genera and 17 families, in which 35 earth-type species to 27 genera and 35 families, and 19 rock-type species to 12 genera and 10 families, 3 species facultative. The species similarity coefficient between two types was 0.22. Probability of interspecific encounter index and Shannon-Wiener index were low, while Simpson index was relatively high. It suggested that the bryophyte distribution in Baili Azalea National Forest Park was significantly influenced by substrates.
