摘　　要：我国土壤镉污染区与水稻种植区在空间分布上基本吻合,这严重威胁了粮食安全与人体健康,是亟需解决的土壤环境问题。伴矿景天是我国近年发现的镉超富集植物,是修复土壤镉污染的理想植物。本文以“伴矿景天”和“Sedum plumbizincicola”为关键词,从中国知网和Web of Science数据库共收集文献280篇,采用文献计量分析软件VOSviewer分析国内外研究现状,分别从伴矿景天对镉的吸收转运和富集机制、解毒机理、田间修复现状、修复效果强化措施和产后处理技术5个方面综述了现阶段的主要研究成果,并进一步阐述了伴矿景天田间修复推广应用面临的问题和挑战,提出未来研究应集中探索伴矿景天的修复效率提升和实际推广应用。The spatial distribution of soil cadmium pollution in China overlaps dramatically with rice cultivation. Cadmium contamination has become one of the most serious problems in food safety and human health. To maintain healthy soils, it is urgent to remediate the cadmium-contaminated soil. Sedum plumbizincicola, a cadmium hyperaccumulator recently found by Chinese scientists, is an ideal plant for remediating cadmium soil contamination. In the present study, 280 papers were retrieved from the CNKI and Web of Science with the keywords‘Sedum plumbizincicola’and analyzed by the software VOSviewer. We discussed the results from the perspectives of physiological and biochemical properties, molecular remediation mechanism, field application mode, and repairing efficiency improvements. After explaining the main problems in field application, future challenges in promoting the field application repairing efficiency were proposed.
