摘　　要：综述了不同生态类型的蚯蚓的特性及其土壤生态功能;总结了其对土壤重金属富集和有效性的作用及影响重金属活化的机理,并指出目前相关的生物化学机理研究的不足及其未来研究方向。同时,文章针对蚯蚓在农业和环境领域的应用现状,提出其应用于重金属污染土壤的植物提取技术的可能性,在未来工作中应加强真实污染土壤室内模拟和田间试验研究,进一步探索筛选和繁育本地蚯蚓品种以及添加有机物等相关技术。This paper summarized the characteristics ot dltterent ecotogmai categories ot earn,- worms and their ecological functions in soil, the effects of the earthworms on soil heavy metal ac- cumulation and bioavailability as well as their mechanisms in affecting heavy metal activation, and pointed out the deficiencies and future directions in the study of related biochemical mecha- nisms. Aimed at the present situations about the applications of earthworm in agricultural and en- vironment fields, it was suggested that earthworm could be used as a biological resource for the phytoextraction of the heavy metals in contaminated soil, more laboratory simulation studies using real soil and field experiments would be required, and to further approach the related techniques for selecting and breeding native earthworm species and for organic matter addition would be the important issues in the future.
