摘　　要：农田土壤重金属污染日益恶化,严重危害居民生活和作物、畜牧安全,影响经济发展,对重金属污染农田的治理成为我国目前亟待解决的环境问题之一。与传统的理化方法相比,植物修复技术因其环保、经济、安全、环境扰动小等特点而备受关注。介绍了农田土壤重金属污染的来源及危害,简述了土壤重金属污染植物修复技术的概念和分类,并针对各种植物修复技术的修复原理、适用情况和研究实例进行详细阐述。综述了当前国内外可用于提高植物修复效率的方法措施,指出了当前植物修复技术存在的修复周期及修复效果的局限性。最后,在现有研究分析的基础上,对今后土壤重金属植物修复技术的发展方向提出了几点展望,以期为今后农田土壤重金属污染植物修复工作提供科学依据。Heavy metal pollution situation in farmland soil is increasingly deteriorating, seriously endangering residents' life, crops and animal husbandry and affecting economic development. The treatment of heavy metal contaminated farmlands has currently become one of the urgent environmental problems in China. Compared with traditional physical and chemical methods, phytoremediation technology has attracted much attention due to its advantages such as eco-friendly, lowcost, safety, and small environmental disturbance etc. This paper introduces the source and harm of heavy metal pollution in farmland soil, and briefly introduces the concept and technical composition of phytoremediation technology for heavy metal pollution of soil. The principles, application and research examples of various phytoremediation technologies are described in detail. The methods and measures that can be used to improve the efficiency of phytoremediation globally are reviewed. The limitations of phytoremediation cycle and effects of the current phytoremediation technology are pointed out. Finally, based on existing researches and analysis, some prospects for the future development of phytoremediation technology for heavy metal pollution of soil are put forward, in order to provide a scientific basis for the future phytoremediation of heavy metal pollution in farmland soil.
