摘　　要：土壤重金属污染问题是我国目前在环境治理方面的一个重大难题,它不仅影响土壤的肥力和功能,还威胁到人类健康和生态安全。土壤重金属的赋存形态决定了它们在土壤中的迁移、转化和生物有效性,因此,了解和分析土壤重金属的形态分布对于评估其环境风险和制定合理的修复措施具有重要意义。本文综述了土壤重金属形态的国内外研究现状,总结了近些年国内学者对不同形态提取方法的研究概论,展望了土壤重金属形态提取方法的发展趋势,并提出了一些改进和创新的建议。The issue of soil heavy metal pollution is a significant challenge in China’s current environmental management. It not only affects soil fertility and functionality, but also poses threats to human health and ecological safety. The speciation of heavy metals in soil determines their migration, transformation, and bioavailability. Therefore, understanding and analyzing the distribution of the speciation of heavy metals in soil is of great significance in assessing their environmental risks and devising reasonable remediation measures. This article reviews the current status of domestic and international research on the speciation of heavy metals in soil, summarizes the introductory research by domestic scholars on different extraction methods for various speciation in recent years, anticipates the development trends of soil heavy metal speciation extraction methods, and proposes some improvement and innovative suggestions.
