摘　　要：抗性微生物对重金属的溶解、络合等作用,提高了重金属在土壤中的生物可利用性,从而增强植物对重金属的吸收富集;其次,抗性微生物分泌的植物激素可以促进植物生长、扩大生物量,进一步提高重金属污染土壤植物修复的效率。为此,对抗性微生物在强化重金属污染土壤中植物修复的作用机制和实际应用方面进行了综述,并分析目前存在的不足及今后的研究方向,以期为发展和提高抗性微生物强化植物修复措施提供理论基础和修复新途径。The dissolution and complexation of heavy metals by resistant microorganisms can improve the bioavailability of heavy metals in soil, thus enhancing the absorption and enrichment of heavy metals by plants.In addition, plant hormones secreted by resistant microorganisms can promote plant growth, expand biomass,and further improve the efficiency of phytoremediation in heavy metal contaminated soil. Therefore, the mechanism and practical application of resistant microorganisms in strengthening phytoremediation in heavy metal contaminated soil were reviewed, and the shortcomings and future research directions were analyzed to provide a theoretical basis and a new way to develop and improve the phytoremediation measures of resistant microorganisms.
