Abstract: Up to now , there have been no special reports regarding soil animals in warm2temperate zone at home and abroad. From April 1993 to January 1994 ,by means of commonly- used quantitative and qualitative method , we carried out monthly sample collections in five plots in the Xiaolongmen Forestry Research Stations , Beijing. A total of 35 294 specimens were collected , belonging to five phyla , six classes , 54 orders , 176 families , 252 genera and 356 species. Among them , 822 individuals were large size soil animals ( Gastropoda , Arachnida , Myriapoda , Hymenoptera etc. ) , 3129 were small size animals (mainly ticks and mites) , 31 227 were wet land living soil animals (mainly nematods) , and annual mean occurrence of individuals per gram of dry soil of Protozoan (mainly Amoebae and Flagellates) was 789 238. The tendency of population fluctuation of dry soil animals showed evident seasonal variations and comparatively obvious fauna characteristics. There are similarities and differences regarding species composition compared with other areas in China and neighbouring countries.
