| 摘 要： | 在内蒙古中部农牧交错区,选择4种不同典型生境,对大型土壤动物群落特征进行了研究.结果表明,该区有大型土壤动物2门4纲11目42科.优势类群为步甲科成虫、蚁科和象甲科幼虫.4种生境由于土地利用方式不同,大型土壤动物群落特征不同、结构也存在明显分异.类群数,人工林地较多,农田较少;密度,荒漠草原较大,退耕地较小;类群数和密度的垂直分布随土层深度增加而呈递减趋势,且表聚性明显.不同生境大型土壤动物类群数和密度随季节变化呈现出不同的变化规律,夏季类群数、密度都高于春秋两季.

| Abstract: | Four typical habitats were selected for the study on the composition features of macro-soil animals community.The results showed that macro-soil animals in the ecotone of the grassland and farmland of the central region in Inner Mongolia belonged to 2 phyla,4 classes,11 orders and 42 families.The dominant groups were imagoes of Carabidae,larvae of Formicidae and Curculionidae.Because of the different land utilizing styles,the features and structures of macro-soil animals communities were obviously different... |
