摘　　要：纳米材料以污染物形式进入土体,并对土体环境产生影响。从理论与实验两个方面对国外相关研究进行了综述分析。理论方面主要参照胶体运移机理对纳米材料在土体中运移过程进行初步解释。实验方面,多以柱淋洗实验模拟纳米材料在孔隙介质中运移过程,并着重探究了影响纳米材料运移性能的主要因素。最后,基于现有研究的成果与不足,提出了相应的研究展望。When nanomaterials entered the soil in form of pollutants,it would have an impact on the soil environment. In this paper,the theoretical and experimental studies abroad were summarized. Theoretically, the transportation process of nanomaterials in the soil was preliminarily explained refering colloid transport mechanism. Experimentally, column experiments were commonly used to simulate the transportation process of nanomaterials in porous media,and the main factors affecting its transportation performance were also explored. Finally,based on the results and shortages of the existing research,the corresponding research prospects were proposed.
