摘　　要：鞍山市大孤山露天铁矿山已有80多年的开采历史,矿山开采对周边和采坑的土地造成了不可避免的生态环境影响。近年来,关于矿山采坑废弃土地的生态环境受到了广泛的关注,而其中土壤动物的种类和数量问题却没有得到应有的重视。通过对鞍山市大孤山铁矿露天采坑不同段阶上废弃地土壤动物的调查研究,查明了自然恢复过程中土壤动物演替的基本生态特征,并对比研究了在人工扰动条件下和自然恢复过程中,土壤动物丰度的特点,总结了自然恢复条件下土壤动物演替的规律性。Mining in Anshan Dagushan Open - Pit Iron Mine which has a history of over eighty years has inevitably had impact on the ecological environment of the surrounding land and the pit land. In recent years ,the ecological environment of the abandoned pit land in mines has aroused wide attention while the quantity and varieties of the soil animals haveat received due attention. Through the investigation on the soil animals on the abandoned pit land at Dagushan Open - pit Iron Mine at different stage benches, the authors revealed the basic ecological characters of the evolution of the soil animals in the natural restoration process, studied the abundance feature of soil animals by comparison between on the land that was artificially disturbed and on the land that was in a natural restoration process and summarized the regularity of the evolution of soil animals under the conditions of natural restoration.
