Abstract: (1)The vertical distribution of Oribatid mite in soil fauna on the foot of the Purple Mountain in Nanjing is aggregated to surface layer of soil.(2)The vertical distribution of this species varies seasonally, with strong surface aggregation in Jun.—May and relatively weak aggregation in June—Dec.(3)Its average density of distribution is higher in Dec.—Feb.,and lower in June-Aug. Relationships between temperature, humidity and food source and the density of Oribated mite have been found.
