2024 individuals of 152 species are captured by sampling investigation on soil animals in purple soil of 5 kinds of different habitat in Yongzhou Area,Hunan,and belong to 5 sorts,10 class,31 orders and 111 families.Of which Tylenchida,Dorylaimida and Acaraina are the dominant orders,14 orders such as Dorylaimida,Hymenopteraetc are the common ones and these two parts of orders form the main bodies of soil animals in Calcarleous Shale of Yongzhou Area.There are certainly differences of animal varieties and quantities in different soils of habitats that animal individuals of nursery,pine-forest are obviously more than that of the other three soils of habitats.And also there are evidently upright delamination,of them that mainly live in the topsoil layer because their varieties and amounts decrease with the increasement of soil animals gradations.The results show that vegetation types and organic contents are main ecological factors that influence on soil animal community structure through analyzing the indexes of destiny-group(DG),variety(D),diversity(H),dominance(C),evenness(E) and comparability coefficient on different habitats.
