摘　　要：丛枝菌根真菌(AMF)作为一种能与大多数植物共生的土壤有益菌,其与植物共生形成的菌根体系在提高植物重金属耐性、强化植物修复重金属污染方面发挥着重要作用。为系统阐述AMF在重金属污染土壤中的作用及其增强植物耐性的机制,本文综述了AMF在植物生长及环境治理方面的应用,着重对其在重金属修复方面的效果进行讨论,并总结了其增强植物重金属耐性的机制(生长稀释及限制吸收作用、抗氧化机制、螯合重金属机制、吸附固持重金属机制),以期为AMF在重金属污染环境中的应用提供科学和理论支撑。Arbuscular mycorrhizal fungi(AMF)is beneficial soil fungi that coexist with most plants.The mycorrhizal system formed by AMF and plants plays an important role in improving plant heavy metal tolerance and strengthening phytoremediation of heavy metal pollution.To systematically examine the role of AMF in heavy metal-contaminated soil and its mechanism of enhancing plant tolerance,the application of AMF in plant growth and environmental management was reviewed and discussed,with emphasis on the effects of AMF on heavy metal remediation.The mechanisms of enhanced plant tolerance to heavy metals(growth dilution and limited absorption,antioxidant mechanism,chelating heavy metals mechanism,adsorption,and immobilization of heavy metals)were summarized to provide scientific and theoretical support for the application of AMF in heavy metal-contaminated environment.
