中国典型地带陆生等足类的区系特点

通过对中国5个典型地带（热带、亚热带、暖温带、温带和高寒带）20个样点采集的72种陆生等足类的区系进行分析，发现具有以下特点：1.分布的地带性强，特有种多；2.东洋界热带，亚热带区系占主导地位；3.物种栖息生境多样；4.与日本区系进行比较发现其种级阶元的差异较大，其中在我国72种陆生等足类中有61种与日本不同，占总种数的84.7%.表明种类分布上具有极强的区系差别.

The Faunastic Characteristics of Terrestrial Isopoda of Typical Zones in China

From an analysis of 72 species of terristial isopoda collected in 20 sampling areas throughout 5 typical zones(i.e.,tropical,subtropical,warm temperate,temperate and high frigid) in China,the author found out the following specific faunastic characteristics among terrestrial isopoda of typical zones:1.with strong regional differences in distribution and more zonal special species;2.the leading position is occupied by the fauna of tropical and subtropical zones of Oriental Realm;3.the ecological habitats among species are diversified;4.as compared with Japanese species,there are big differences between species category.More than 84% indigenous Chinese species are different from Japanese species,indicating the existence of further strong faunastic diffeences on species distribution.
