Abstract: 【Objective】 Tto find out the effects of different land use type habitats on soil mite community diversity in agroecosystem at the southwest margin of Flaming Mountain in the hope of providing scientific basis for the protection of soil biodiversity, sustainable development and biological evaluation of environmental quality. 【Methods】 The diversity characteristics of soil mite communities in ten land use types of agroecosystem in the southwest margin of Flaming Mountain in Turpan were analyzed by field sampling and improved Tullgren method. The improved Tullgren method and morphological classification method were used to classify the soil mites and analyze the characteristics of community structure. 【Results】 A total of 21,195 soil mites were collected, belonging to 100 genera, 68 families and 4 suborders, among which, Protoribates was the dominant group, and Berniniella Balogh, 1983 and Monogalumnella Mahunka,1986 were newly recorded genera in China. There were significant differences in the number of individuals, groups and diversity indices of soil mites in different habitats of land use types (P< 0.05), in which the diversity of vineyards was the highest, while that of desert was the lowest. There were seasonal differences in community diversity, with the highest in autumn and the lowest in summer. The main predatory mites were K-selection type, and oribatid mites were O-type and P-type. 【Conclusion】 The results show that there are significant differences in the diversity indexes of mite communities among different land use types, and the main factors affecting the diversity of soil mite communities are surface litter and human disturbance.
