摘要： 生物有效性能够反映重金属的迁移性及其生物可利用性，在重金属污染土壤稳定化修复后评估中受到广泛关注。为了将生物有效性更好地应用到稳定化后评估过程中，系统地归纳总结了土壤中重金属对蚯蚓的生物有效性评估方法，该方法与多种化学试剂浸提之间的对应关系，以及影响生物有效性评估的相关因素。建议在化学浸提基础上结合生物有效性评估方法对重金属污染土壤稳定化修复效果进行评估。

Abstract: Bioavailability can reflect the migration and bioaccessibility of heavy metals and it has been widely used in the post stabilization remediation of soils contaminated with heavy metals. To facilitate the use of bioavailability in post stabilization remediation assessments, the methods used to evaluate the heavy metal bioavailability to earthworms in soil were systematically summarized. In addition, the corresponding relationship between these methods and the chemical reagents used for extraction, as well as the factors affecting the bioavailability evaluation methods, were also summarized. Therefore, it is suggested that the effects of the stabilized remediation of soil contaminated with heavy metals be evaluated based on chemical extraction, combined with bioavailability evaluation methods.

Key words: heavy metal, earthworm, bioavailability, chemical extraction, bioaccumulation
