摘　　要：研究表明:黄石地区共分布有苔藓植物21科34属34种,苔类6科6属6种,藓类15科28属28种;5个优势科按种类多少依次为:丛藓科Pottiaceae,青藓科Brachytheciaceae,羽藓科Thuidiaceae,真藓科Bryaceae,牛毛藓科Ditrichaceae;黄石地区苔藓植物分为固着型、根着型、浮生型3种生活型;并依据生境不同分为4种群落类型:水生群落、树生群落、土生群落、石生群落,其中以土生群落为主体,树生群落、石生群落次之,水生群落种类最少。This paper reports the results of the preliminar study on the Bryphytarum communities in Huangshi.The Bryphytarum consists of 34 species in 34 genera 21 families,of which Hepaticaes is 6 species in 6 genera and 6 families,Musci is 28 species in 28 genera and 15 families.There are five dominant families of Bryphytarum in Huangshi： Pottiaceae,Brachytheciaceae,Thuidiaceae,Bryaceae and Ditrichaceae.There are three types of the life-forms： Adnata,Radicantia,Floatia.Four ecological types of communities can be distinguished according to the habitat of Bryphytarum： Hydrophytia,Geophytia,Epixylophytia,Petrophyti.Among them,Geophytia is major,Petrophyti and Epixylophytia are media,and Petrophytia is little.It offers the basic data and information to the study of the biological diversity in this paper.
