摘要/Abstract

摘要：通过对中国5个典型地带（热带、亚热带、暖温带、温带、高寒带）20个样点进行陆生足类的调查采集，共发现陆生等足类11科、29属、72种.其中以喜湿虫科(Philosciidae)的种类最为丰富，共计4属、19种，约占总数的26.4%；气肢虫科(Tachelipidae)为第2大类群，计有5属、18种，约占总数的25%；卷壳虫科(Armadillidae)共有7属、10种，为第3大类群，约占总种数的13.9%；鼠妇科(Porcellionidae)、卷甲虫科(Armadillidiidae)及潮虫科(Oniscidae)也是陆生等足类的主要类群，这3科共占总种数的16.5%；其它5科的陆生等足类种类较少，合计13种.由于各地带自然环境明显不同，造成了物种分布上的差异.其中热带和亚热带地区种类最多，分别为38种和47种，共占总种数的80%以上；暖温带和温带地区仅发现9种；而高寒带由于平均气温在0 ℃以下，不利于陆生等足类的生存,故迄今仅发现2种.

Abstract: From an investigation and collection of specimens of terrestial isopoda in 20 sampling areas throughout 5 typical zones (i.e.,tropical,subtropical,warm temperate,temperate and high frigid) in China,a total of 11 families,29 genera and 72 species of terrestial isopoda were found.Due to the great zonal differences in the environmental surroundings,there are diversities in species distribution.Tropical and subtropical zones are mostly rich in number of species with a total of 38 and 47 species respectively,making up more than 80% in total.Only 9 species were found in temperate and warm temperate zones.In high frigrid region,due to the average temperature which is below zero degree celsius and which is unfavourable for the existance of terrestial isopoda,only 2 species were found.

Key words: typical zone, terrestrial isopoda, species construction, fauna distribution
