Abstract: To reveal the community structure of soil fauna in different managements in urban lawn, no weeding, weeding and trampled grassland were chosen as sample plots in July 2015. Soil macro-fauna were picked up by hands. nematodes and meso-fauna were separated and collected from the soil samples by Baermann and Tullgren methods, respectively. Results showed that soil fauna had 1 009 individuals, belonging to 2 phylums, 11 classes, 20 families. The order of the average density of soil fauna was no weeding (3.84×104 ind.·)>weeding (3.63×104 ind.·)>trampling (2.79×104 ind.·). The order of species number was no weeding (33)>weeding (27)>trampling (20). There were significant differences between no weeding and weeding on the density-group index (DG) (P<0.05). The various diversity index (H') among the lawn managements were not significantly different (P>0.05), while the specie numbers of soil macro-fauna were significantly different (P<0.05). Results indicated that the richness, diversity and homogeneity of soil fauna were closely negatively correlated with intensity of human interference.
