摘  要：
The soil fauna community structure and diversity were investigated in four different types of habitats in Shabianzi,Ningxia from June to September in 2006. The relationship between soil fauna and the soil physical and chemical characters was analyzed. Total 4 270 species of sandland soil animals were obtained belonging to 3 classes,14 phyla,28 families,33 genera. The dominant animals were those genera from Collembola,Neanridae Paronellidae and Isotomidae,while the rare fauna was genus of Orthoptera.The number of soil animals in the fixed sand land was the most biggest,followed by fixed sand land>semi-fixed sand land> Inter-dune lowland > drifting sand dune. Soil fauna diversity,similarity and cluster analysis,showed that the index of DG was the better index for measuring the soil fauna diversity,and in this study the DG was in order as follows:semi-fixed sand land> fixed sand land > Inter-dune lowland > drifting sand dune.
