摘　　要：根据过去三年的调查研究,湖北星斗山自然保护区共有藓类植物26科68属191种7变种,其中种数较多的科主要有青藓科,曲尾藓科,丛藓科等.星斗山自然保护区藓类植物的区系地理成分可划分为9类,其中以东亚成分(40.35%)和北温带成分(19.88%)为主,热带亚洲成分(18.71%),表明了星斗山自然保护区是热带、亚热带成分向北扩展和北温带成分向南渗透的过渡地带.Xingdoushan Nature Reserve lies in the west Hubei,with the area of 846.67 hectares.Based on our investigations in the past three years,a total of 191 species and 7 infraspecific taxa belonging to 68 genera and 26 families have been found in Xingdoushan.The principal families of the local bryoflora are Brachytheciaceae,Dicranaceae,and Pottiaceae,etc.,Nine floristic patterns are recognized for the mossflora of Xingdoushan.The distribution patterns of East Asia and Temperate elements are the two commonest（40.35% and 19.88% respectively）.The results show that the Xingdoushan Nature Reserve is transitional climatic belt where the tropical and subtropical elements extend northwards and the North Temperate elements infiltrate southwards,which accords with its geographical location.
