The data on the soil micro-arthropodes under four land utilization types (fallow,forest,upland field and paddy) in the Lower Reaches of Liaohe River Plain were collected in a period from October 2000 to October 2001.Using the community parameters of population density,group richness,diversity index and evenness,the community structure and its seasonal changes were described.There were 12 groups of soil micro-arthropodes in this region,and of the groups,Collembola and Acarina were dominant,and Diptera,Coleoptera and Hymenoptera were often seen in fallow,forest and upland field,while Collembola,Acarina and Diptera were dominant in paddy.Both land utilization and seasonal change influenced the population density,group richness and diversity index of soil micro-arthropodes.The vertical distribution in both density and group number of arthropods in soil was in the order of surfacemiddlebottom.
