摘　　要：近年来随着核工业的发展和核能的应用,铀污染土壤问题逐渐引起人们的重视。与此同时,物理、化学、生物等土壤污染修复技术也得到快速发展,其中植物修复以其绿色环保、成本较低、无二次污染、可大面积修复等优点被广泛应用于铀污染土壤修复。综述我国部分铀矿山铀污染土壤的分布特征及植物修复、螯合剂-植物修复、植物-微生物修复四方面研究进展,并对螯合剂增强植物-微生物联合技术进行讨论与展望。With the development of the nuclear industry and the application of nuclear energy,the problem of uranium contaminated soil is becoming more and more serious.At the same time,physics,chemistry,biology and other soil pollution remediation technologies have also been rapidly developed.Phytoremediation is widely used in uranium contaminated soil because of its advantages of green environment protection,low cost without secondary pollution and large scale remediation.In this article,four aspects are reviewed:uranium-contaminated soil distribution characteristics,phytoremediation,chelating agents-phytoremediation,phyto-microbial remediation.Finally,the application of slow-release chelating agents in phytoremediation combine with microorganism technology is discussed and predicted.
