摘　　要：随着沿海地区的工业化加速,工业区周边的土壤面临着重金属污染的威胁,造成许多植物无法正常生长,而筛选和施用耐重金属微生物是提高植物生长的重要技术之一。文章总结了重金属耐性微生物的耐性机理,归纳了5种重金属耐性微生物的分离筛选方法,分析了微生物修复重金属污染的影响因素,为微生物修复重金属污染、提高植物抗逆性提供理论依据。With the acceleration of industrialization in coastal areas, many plants are facing the threat of soil organic matter shortage and heavy metal pollution, which makes many organisms in this area unable to grow normally. Screening and application of heavy metal-tolerant microorganisms is one of the important technologies to improve plant growth.This paper summarizes the tolerance mechanism of heavy metal tolerant microorganisms, summarizes the isolation and screening methods of five heavy metal tolerant microorganisms, summarizes the species of their tolerant strains,and analyzes the influencing factors of microbial remediation of heavy metal pollution, so as to provide an academic foundation for microbial remediation of heavy metal pollution and improving plant stress resistance.
