Abstract: [Objective] This paper studied on the effect of different land use types on soil macrofauna community structure. [Method] Soil macrofauna was collected with method of hand picking, and the community characteristic of soil macrofauna was described by Shannon-wiener index (H'), Pielou index (J), Simpson index (C), Margalef index (D)and DG index (DG);data was analyzed by SPSS 16.0 software. [Results] A total of 181 soil macrofauna individuals were collected, which belonged to 25 groups. Microdrile oligochaetes and Hymenoptera were both the dominant groups. Number of soil macrofauna groups in abandoned land was the least. The number of soil macrofauna individuals in different soil types varied as followed:graden (41 individuls) > farmland (40 individuals) > orchard (34 individuals) > lawn (23 individuals)=building site (23 individuals) > abandoned land (20 individuals). The number of soil macrofauna groups decreased with depth increase of soil layer, showing obvious surface aggregation phenomenon under different soil types except building site (P<0.05), it was the same as individuals except abandoned land and building site (P<0.05). The community characteristic of soil macrofauna was asfollows:diversity of soil macrofauna from farmland was highest, diversity of soil macrofauna from orchard and garden were lower, and it was the lowest of the diversity of soil macrofauna from abandoned land, lawn and building site. [Conclusion] All in all, Microdrile oligochaetes and Hymenoptera were the dominant groups, and surface aggregation phenomenon was existed in soil macrofauna under different soil types. Community structure of soil macrofauna in farmland was complex, but diversity of soil macrofauna in abandon land, lawn and building site was low. So, sever human disturbance, rare or simple vegetation had disadvantage effect on the survival of soil macrofauna.
