[Objective] The study aimed to investigate the soil animal communities from 4 kinds of greenbelt habitats in Baoding City.[Method] The species,quantities and distribution characteristics of the soil animal communities from different types of greenbelts in Baoding City were studied through sampling investigation and statistical identification on the soil animal communities from 4 greenbelts including nursery,road,protection forest and park in Baoding City.[Result] The sampled identification showed that,a total of 1 462 soil animals were collected from 4 greenbelts,belonging to 14 orders,8 classes and 2 phyla.The dominant groups were Aconite,Collembola and Hymenoptera,while Tubificidae,Arenas,Isopoda,Diplura,Coleoptera larvae were the ordinary groups and others were rear groups.The composition of soil animals in the 4 kinds of greenbelt habitats was extremely similar.The animal density in unite soil for 4 kinds of greenbelt in order was as follows: nursery greenbelt park greenbelt road greenbelt protection greenbelt.[Conclusion] The soil animals distributed mainly in the soil layer of 0-10 cm,with most number in soil layer of 0-5 cm,showing the obvious surface aggregation phenomenon,which had a close relation to the greenbelt habitats.
