Abstract
The paper based on 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 4 dominant families.According to the area-types of Chinese genera of seed plants by Wu Zheng-yi.The result shows that North temperate elements and East Asian elements are most important two,one of which corresponding to 31.34% of total.Followed by East Asian elements and North temperate elements,Endemic to China is next which corresponds 13.43% of total.It can be concluded that temperate elements are main body of Bryophytes of urban areas of Zunyi.
