摘　　要：在内蒙古农牧交错区,选择4种不同典型生境,对大型土壤动物在物质循环中的作用进行了研究。结果表明,大型土壤动物对元素富集大小为:K>Ca>Mg>Fe>Na>Zn>Mn>Cu;在4个生境中,大型土壤动物元素的富集量:人工林地较高,农田较低。农田大型土壤动物对Ca富集较高,退耕地、人工林地和荒漠草原大型土壤动物对K富集较高。Four different typical habitabs were selected for study on the effect of macrofauna on the material circulation in the ecotone of grassland and farmland of Inner Mongolia.The results showed that the size of chemical elements enriched in the bodies of macrofauna is：KCaMgFeNaZnMnCu.In four habitats,the contents of chemical elements enriched in the bodies of macrofauna are higher in artificial woodland and those are lower in farmland.The contents of Ca enriched in the bodies of macrofauna are higher in farmland and the contents of K enriched in the bodies of macrofauna are lower in artificial woodland,abandoned Lands and desert steppe.
