摘　　要：以干重量表示苔藓群落优势度,对日本长崎县长崎市小江源町、谏早市城见町、大村市上诹访町和佐世保市中心大街苔藓群落物种多样性进行调查分析.结果表明,人类活动负面影响较少的住宅区、公园和神社院内苔藓群落H′值范围为0.459~1.916,平均值为1.121;路旁、耕地、庭院(人家)、公园及神社周边地区大部分苔藓群落H′值范围为0.001~0.436,平均H′值为0.179,前者优势度显著高于后者,即前者物种多样性高于后者.Species(alpha)diversity of bryophyte communities in Koebaru-machi in Nagasaki City;urban districts in Isahaya City;urban districts in Omura City;urban districts in Sasebo City,in Nagasaki-ken,Japan)was analyzed based on the dominance of bryophyte community in terms of dry weight.The range of H′value of bryophyte community was 0.459~1.916 with an average of 1.121 in residential areas where human activity has less negative impact,parks and shrines.The range of most of bryophyte community was H′value 0.001~0.436 with an average of 0.179 in roadsides,arable land,courtyard(family)and areas around parks and shrines.The dominance of the former was significantly higher than that of the latter and the species diversity of the former was higher than the latter.
