In order to understand the characteristics of community structure of soil mites in the mixed evergreen and deciduous broad-leaved forest in Fanjingshan, soil mites were investigated in June 2015 along an altitude gradient, a total of 2 100 soil mite individuals was captured which belong to 4 suborders, 55 families and 101 genera. The characteristic of soil mite community structure was analysed by using number of taxon and individual, diversity, dominance, evenness, MGP analysis and MI index. The results showed that Vilhenabates and Setoxylobates were the dominant groups for the whole forest belt, and the distribution of mites presented an upper-accumulated nature. With the increase of altitude, the quantities of both communities and individuals of mites were basically reduced. The dominance of soil mite communities in different altitudes was characterized by an order of 1 300 m>1 900 m>1 500 m>1 700 m, while the diversity and evenness indexes in an order of 1 700 m>1 900 m>1 500 m>1 300 m. Further variance analysis also indicated that altitude had a significant impact on the dominance of mites, but little effect on the diversity and evenness indexes. The community structures of Oribatid and Mesostigmatic mites were respectively dominated by O-type and K-selection.
