Abstract: 【Objective】In order to learn the effects of land-use on macro-arthropods community. 【Method】The soil macro-arthropods in the black soil region in Jilin Province were investigated with the emphasis laid on the species richness and abundance in relation to the types of land-use i.e. farmland, farm garden and Three-North Forest Shelterbelt. The soil macro-arthropods were hand-sorted in the field. 【Result】A total of 2 357 soil macro-arthropods individuals was captured and fell into 5 classes, 9 orders and 70 families.【Conclusion】The results suggest that the types of land use affect the species richness and abundance, and human activity has a significant impact on the soil macro-arthropods community. The agricultural activities change their vertical distributions in the soil profile, and improve the richness and abundance of macro-arthropods in the lower soil stratum especially in July. The results also show that different soil macro-arthropods are sensitive to changes of land use.
