摘　　要：随着对蚯蚓生态功能的深度挖掘,近年来开发出一种新型的污染物、废弃物处理处置技术:蚯蚓堆置处理技术.文章从蚯蚓生态型差异、土壤类型、重金属类型差异、pH值以及可溶性有机碳变化4个方面论述此技术对土壤中重金属生物可利用性的影响,以期为今后研究工作提供参考.Vermicomposting, which was a disposal technology for waste and contaminants, was recently developed along with the deep exploitation of earthworm ecological functions. The paper exposed the effects of the technology on the bioavailability of heavy metals in soil from four different perspectives of earthworm ecological differences, soil categories, heavy metal category differences as well as the change of pH and dissolved organic carbon （DOC）, the results can provide references for future work.

关 键 词：蚯蚓 生物可利用性 蚯蚓品系 土壤类型 重金属特异性
