A study on the bryoflora from urban areas of Zunyi city,Guizhou province, China

The paper based on the research of 150 speciments collected from Fenghuang Montain,Sange Park,Xiangjiang River and Dingzikou of urban areas of Zunyi,After this study,19 families,41 genera and 70 species(including subspecies and varieties) are identified,there are 66 species,belonging to 37 genera of 15 families,while for liverworts,4 families,4 genera and 4 species were identified.Pottiaceae 、Bryaceae、Hapnaceae and Brchytheciaceae are the 4 dominant families.According to "the area-types of Chinese genera of seed plants" by Wu Zheng-yi.The result shows that the North temperate elements and East Asian elements are the most important two,one of which corresponding to 31.34% of the total.Followed by the East Asian elements and the North temperate elements,Endemic to China is the next which corresponds 13.43% of the total.It can be concluded that the temperate elements are the main body of the Bryophytes of the urban areas of Zunyi.
