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
