摘　　要：土壤重金属污染已成为全球关注的热点环境问题之一,其治理与修复成为当今社会经济发展的重大科技需求。土壤动物蚯蚓-植物联合修复成为治理土壤重金属污染的新途径,研究颇多。该文基于国内外大量文献,从蚯蚓活动改变土壤理化性质加速植物修复重金属、蚯蚓与微生物相互作用促进植物修复重金属、蚯蚓分泌液与排泄物改变重金属形态影响植物修复重金属3方面阐述蚯蚓在植物修复重金属污染土壤的重要作用,为后续相关研究提供理论参考。Soil heavy metal pollution has become one of the hot environmental issues of global concern, and its treatment and remediation has become a major scientific and technological demand for social and economic development. Soil animal earthworm-plant remediation has become a new way to control soil heavy metal pollution. Based on a large number of documents at home and abroad, this paper expounds the important role of earthworms in phytoremediation of heavy metal contaminated soil from three aspects, including changing soil physical and chemical properties from earthworm activities to accelerate phytoremediation of heavy metals, promoting phytoremediation of heavy metals by earthworm and microbial interaction, change of heavy metal morphology by earthworm secretion and excrement to affect phytoremediation of heavy metals, so as to provide theoretical reference for subsequent related research.
