摘　　要：以土壤微团聚体为对象研究重金属吸附的结果更接近田间实际状况,其结果作为预防和修复土壤的重金属污染的依据更有实际意义。对土壤微团聚体分组方法、分配比例以及微团聚体中有机质、铁铝氧化物的含量和表面电荷等基本性质进行了简要的综述,分别对微团聚体基本性质、pH和磷处理等因素对金属离子吸附的影响作了论述,进一步描述了微团聚体吸附重金属的动力学的研究进展,并对今后研究方向进行了探讨。The research of micro-aggregates can highly simulate to the results in field. This research is more useful in preventing and remediation of heavy metal pollution. This paper reviewed the separated method of micro-aggregates, distribution, the proportion of organic matter, Fe（A1） oxyhydrates and the surface charge in the soils. It respectively introduced the effects of the basic properties of micro-aggregates, pH and phosphate pre-sorption on heavy metal adsorption. Finally, it described the study progress of adsorption kinetics, and some aspects of further studies are proposed.
