The paper reported the results of study on the composition, vertical structure, diversity and similarity of soil Oribatid mites at the different habitat in Fanjing Mountain. The genus and amount of Macropylina are abundant. Tectocepheus,Oppiella,Xylobates,Perxylobates are dominant fauna. Tectocepheus is the particularly dominant genus of Fanjing Mountain. The diversity of soil Oribatid mites declines with the rising of altitude. The content of organic matter in soil influences the amount of soil Oribatid mites mainly. The structure of soil Oribatid mites is also impacted by the direction of slope, the gradient and the people's activities. The comparison of diversity of soil Oribatid mites at five plots is as follows: the plot's of altitude 750metre at eastern slope (A) the plot's of altitude 1 500metre at western slope (D) the plot's of altitude 1500metre at eastern slope (B) the plot's of altitude 750metre at western slope (C) the plot's of the Gold Peak (E). The individual quantities of Malaconothrus at the plot E and Masthermannia at the plot C are much more than other plots'. The individual quantities of the plot D are excessively more than other plots'. The soil Oribatid mite communities of the plot A and C are most similar, and those of the plot C and E are most unlike.
