【Objective】Soil fauna play a significantly crucial role in decomposing organic debris, altering physical and chemical properties, and promoting material and energy recycling of and in the soils. In addition to this, they are a key link between the above- and under-ground ecosystems. Change in land-use may bring about great impacts on the ecosystems. However, little has been reported on impacts of changes in land use on soil fauna communities in the Changbai Moutains. In this study, a field investigation was conducted in 2014 on composition, diversity and distribution of the soil fauna communities in four tracts of land different in land-use (secondary deciduous broad-leaf forest, shrubbery, cut-over land and farm land) in the Changbai Mountains. 【Method】 Sampling plots, 5 m×5 m each, were set up in the cut-over land and the farm land, and, 10 m×10 m each in the secondary deciduous broad-leaf forest land and shrubbery land. Within each plot, five subplots were set using the diagonal process for duplicate sampling, 25 cm × 25 cm each for macro-fuana and 10 cm × 10 cm each for meso-fauna, and samples were collected from the litter layer, 0~5, 5~10 and 10~15 cm soil layers in each subplot during spring, summer, and autumn 2014. Soil macro-fauna were picked out and collected by hand and soil meso-fauna with the Tullgren funnel extractor. One-way ANOVA and LSD were adopted to analyze differences in soil fauna community between lands under different land use, and RDA (redundancy analysis) to analyze relationships of soil fauna community with soil physico-chemical properties relative to land use.【Result】A total of 59 groups and 16 344 soil animals were collected and could be sorted into 3 phyla, 7 classes and 21 orders/suborders. Among these, Oribatida (27.04%), Actinedida (20.94%) and Isotomidae (16.05%) were the dominant groups. Differences between the four tracts of land were significant in soil fauna distribution at the community level. In the cut-over land, individual density of the soil meso-fauna varied significantly with the season, while in the farm land the number of soil meso-fauna groups did. In the secondary deciduous broad-leaved forest land and shrubbery land, the soil fauna community declined drastically in distribution with with soil depth, while in the cut-over land and farm land did not so drastically. Even in the same season, the four lands differed in Margalef index (D index) and Shannon-wiener index (H’ index) of the soil macro-fauna. Only in the cut-over land, D index varied significantly with the season. In the same season, the four lands differed in D index and H’ index of the soil meso-fauna. The secondary deciduous broad-leaved forest land, cut-over land and farmlands varied significantly in H’ index of the soil meso-fauna, while the secondary deciduous broad-leaved forest land and shrubbery land did in D index. Redundancy analysis shows that soil fauna was significantly related to pH, organic matter, readily available P, readily available N, moisture content and temperature in the soil in community diversity and distribution. 【Conclusion】Obvious differences did exist between lands different in land use in distribution of soil fauna in community level in the Changbai Mountains. In the cut-over land the soil meso-fauna varies significantly with the season in individual density, while in the farm land, it does in number of groups. In the secondary deciduous broad-leaved forest land and shrubbery land the soil fauna communities decline drastically with soil depth, while in the cut-over land and farm land they do quite mildly. The shrubbery land is the highest in soil fauna community diversity and the farm land the lowest. RDA shows that soil pH, soil organic matter content and the content of readily available P and readily available N are the main factors affecting distribution of the soil fauna communities in all the four types of lands in the hilly regions of the Changbai Mountains.
