摘　　要：对平朔安太堡露天煤矿排土场恢复生态系统5种植被模式下的大型土壤动物进行调查,共获取大型土壤动物246头,分属于2纲、9目、24科。利用DIC与DG多样性指数对其群落结构进行分析。结果表明:大型土壤动物多样性由多到少的次序为:针阔叶混交林,乔灌混交林,草;针叶混交林,灌木;大型土壤动物密度与土壤有机质、土壤含水量密切相关;大型土壤动物类群数与土壤容重、含水量密切相关。影响土壤动物生存的土壤物理条件是恢复生态系统土壤动物回迁的主要因素。土壤的肥力是影响土壤动物繁殖的主要因素。Soil macro-fauna communities under different recovery ecosystems with different plantations in Antaibao opencast coalmine, Pingshuo, Shanxi, China are investigated. A total of individuals 246 belonging to 24 families, 9 orders, 2 classes of soil macro-fauna were collected. The results indicated that, the multiplicities of the soil macro-fauna are ordered by conifer × broadleaf tree〉 arbor × shrub 〉grass; mixed conifer〉 shrub. There are obvious relationships between density of soil fauna and soil organic content, nature moisture. There are obvious relationships between special number of soil fauna and soil bulk density, nature moisture. Soil physical properties are the main factors to the soil macrao-fauna restoration. Soil fertilities are main factors to culture of soil macrao-fauna.
