摘　　要：随着多环境介质问题研究的深入,重金属在跨介质迁移时产生的界面效应问题倍受人们关注。土－岩界面因其特有的微环境结构和特性,使重金属在该界面的行为过程既部分地表现出与在两侧的环境介质运移过程的动力学特征及机制,又有其独特的特性。有关研究表明自然因素及人为活动等引起的环境参数的变化对土－岩界面的重金属行为有显著影响。今后土－岩界面的重金属行为研究应在目前研究状况的基础上立足于为土壤污染的修复提供技术支撑。With the studies on the environmental multimedia advanced, interfacial effects, brought forth by heavy metals' transfer between environmental media, attracted more and more attention. Because of soil-rock interfaces' microenvironment structure and characteristic, there are some unique kinetics processes and mechanism of heavy metals behaviors in it besides some similarity to that in each medium. Some researches have proposed that the variation of environmental parameters caused by natural factors and human activities plays great roles on behaviors of heavy metals. Meanwhile the paper indicated that some questions should be focused on in relative researches in the future.
