Abstract: The composition and ecological characteristics of bryophyte communities were investigated from three peak clusters of karst rock desertification in Zhenfeng county, Guizhou province. There are 21 types of bryophyte communities in the area, in which pure communities take up 83.3% and those with more than two species take up 26.7%. The predominant communities are Anomodetum, Hyophiletum and Trichostometum. There are only two lifeforms which are Wefts and Short turfs occurred on the area owing to the dry and strong light environment. In karst rock desertification peak cluster, bryophyte communities are rich in peak and scarce in bottom. The results indicate that the Anomodetum has the potential value to control rock desertification contributing to its highest ecological dominance presenting all sites.

Key words: bryophyte communities, karst rocky desertification, peak cluster, ecological characteristics
