摘　　要：植物修复技术以其成本低廉和对环境的友好性,成为治理重金属和放射性核素污染的有效手段。在铀矿开采和冶炼过程中产生的^(226)Ra是一种具有长半衰期的α核素,一旦释放到环境中,便可能通过食物链对人类健康构成潜在威胁。因此,研究^(226)Ra在土壤-植物系统中的吸收和转运机制及其影响因素,对于开展^(226)Ra污染土壤的植物修复工作至关重要。通过调研国内外关于镭的生物地球化学循环、镭从土壤到植物的吸收转运机制及其影响因素的研究,分析了镭污染土壤的植物修复策略及其可行性,提出了提升镭污染土壤植物修复效率的建议。Plant remediation technology has become an effective means of controlling heavy metal and radioactive nuclide contamination due to its low cost and environmental friendliness.^(226)Ra produced during uranium mining and smelting is an alpha nuclide with a long half-life.Once released into the environment,^(226)Ra may pose a potential threat to human health through food chain.Therefore,studying the absorption and transport mechanisms of^(226)Ra in the soil plant system and its influencing factors is crucial for carrying out plant remediation work on^(226)Ra contaminated soil.By conducting research on the biogeochemical cycle of radium,the absorption and transport mechanisms of radium from soil to plants,and their influencing factors both domestically and internationally,this study analyzed the plant remediation strategies and feasibility of radium contaminated soil,and proposed suggestions to improve the efficiency of plant remediation of radium contaminated soil.
