摘　　要：土壤汞污染及其治理是当前汞环境地球化学研究的核心内容之一。与传统物理和化学修复技术相比,植物修复技术对环境扰动小,修复成本低,是目前汞污染土壤修复领域的主要热点方向。本文主要从汞污染土壤植物修复原理和应用两方面入手,总结了土壤汞污染特点、植物修复技术原理及过程、修复植物与潜在修复植物种类、植物修复强化措施。针对现有研究的不足,对植物修复汞污染土壤的研究方向和发展趋势进行展望,以期为汞污染土壤植物修复技术应用与发展提供科学参考。Soil mercury contamination and its remediation is one of the core issues of mercury environmental geochemistry.Physical and chemical methods for the treatment of mercury-contaminated soils have serious limitations due to the high cost,low efficiency and the secondary pollution concerns.Phytoremediation is receiving increasing attention in the light of inexpensive,efficient,and environmental and eco-friend traits.In this review,the principle of phytoremediation of mercury-contaminated soils and the application of this technique has been summarized which include the characterization of soil mercury contamination,the principle and process of phytoremediation technique,suitable plants and potential suitable plants for phytoremediation,and the enhancement measures of phytoremediation are discussed.In view of the shortcomings of the existing research,the research direction and development trend of phytoremediation of mercury contaminated soil are prospected,in order to provide scientific reference for the application and development of phytoremediation technology of mercury contaminated soil.
