摘　　要：土壤是重金属的重要受体,重金属具有高毒性和易积累等特征,很难在环境中降解,重金属不仅是生态环境的杀手,还会对人的健康造成影响,土壤污染防治是我国生态文明建设的重要内容,因此人们日益重视土壤的重金属污染问题。对国内外的土壤重金属污染研究进行了详细梳理,围绕着土壤重金属污染现状影响、治理修复技术研究现状及未来展望3个方面展开,比较了物理、化学及生物土壤修复方法的优缺点,发现与其他方法相比,单一修复法已不能满足当前的修复任务,联用技术具有更加广阔的前景和应用场景,对联用技术发展的方向进行了展望,根据目前污染的实际情况提出了从源头治理与防治手段结合、利用互联网技术加快修复行业发展、因地制宜使用联合技术、加快技术创新与研发、加强立法和监管等具体对策建议。Soil is an important receptor of heavy metals with high toxicity and easy accumulation,which are difficult to degrade in the environment.Heavy metals are not only the killer of ecological environment,but also affect people's health.Soil pollution prevention and control is an important part of China's ecological civilization construction,so people pay more and more attention to the problem of soil heavy metal pollution.This paper reviews the research on soil heavy metal pollution at home and abroad in detail from the present situation of heavy metal pollution in soil,the research status and future prospect of remediation technology.The advantages and disadvantages of physical,chemical and biological soil remediation methods were compared.It was found that compared with other methods,the single remediation method could not meet the current remediation task,and the combined technology had broader prospects and application scenarios.The development direction of combined technology was prospected.According to the actual situation of pollution at present,some specific countermeasures and suggestions are put forward,such as combining source control with prevention measures,using Internet technology to speed up the development of remediation industry,using combined technology according to local conditions,speeding up technological innovation and research and development,and strengthening legislation and supervision.
