Abstract:Community diversity and ecological distribution of soil animal in suburb of Linfen city was investigated by species surveying in 7 sites (woodland,farmland,orchard,road green belt,abandoned beach,heavy metal contaminated area of farmland and woodland)from April to October 2009.The soil in site 1,2,and 3 is not polluted,in site 4 and 5 is moderate polluted and in site 6 and 7 heavily polluted.We totally captured 5 842 individuals of soil animal,representing 4 Phyla,9 Classes,25 Orders.Three Order,Collembola,Acarina and Hymenoptera,were dominant,14 Orders were common and 8 Order rare in the samples.The individual abundance of soil animal was autumn> spring > summer.In the consideration of the soil animal vertical distribution,soil animals concentrated obviously in the surface layer (0-5 cm from surface) in site 1,2 and 3,while in site 4 and 5 soil animals were almost equally in the layer 0-5 cm,5-10 cm,and 10-15 cm from surface,then reduced in layer 15-20 cm; However,more individuals of soil animal were collected from layer 5-10 cm and 10-15 cm than from surface layer in site 6 and 7.Species diversity index (H’),dominant index (C),and richness index (D),varied more greatly in summer,while evenness index was relatively stable.The proportion of saprophagous animals was highest in the heavy metal polluted site,while phytophage animal was dominant in site 2 covered by wheat.
