摘　　要：依据淮北相山的土壤类型、地形、植被等特点,选择3种不同的样地对其中的土壤甲螨的多样性进行了调查.调查共获得甲螨标本1 185头,隶属于21个科,27个属.全区的优势属为小奥甲螨属Oppiella、木单翼甲螨属Xylo-bates、窝甲螨属Fosseremus.全区的多样性Shannon-Wiener指数为2.687,均匀度Pielou指数为0.815,优势度Simp-son指数为0.090.3种采样点中,样地Ⅱ的多样性指数高,而样地Ⅲ的均匀度指数和优势度指数最高.In order to investigate the diversity of soil oribatid mites in Xiangshan mountain of Huaibei,three sample plots were selected based on the type of soil,terrain and vegetation.1185 specimens which belong to 21 families and 27 genus were collected.The results show that Oppiella,Xylobates and Fosseremus are the dominant genus in the investigation region.The Shannon-Wiener index is 2.687,the Pielou index is 0.815,and the Simpson index is 0.090 in the investigation region.Among the three sample plots,the Shannon-Wiener index of the plot Ⅱ is the highest;however,the Pielou index and the Simpson index of plot Ⅲ are the highest.
