Lasius Tetramorium and Achaeta were the dominant groups that accounted for 49.20% of the total individuals. The results suggested that the types of land use affected the species richness and abundance, and human activity has a significant impact on the soil macro-animals community. Agricultural activity reduced soil macro-animal diversity, but did not change their vertical distributions in the soil profile. The results also showed that the differences in the composition of the soil macro-animal community between the middle plain and the west plain in Jilin Province were mainly explained by the dominant group density and rare group numbers in all habitats.
