摘　　要：土壤重金属污染面积大,波及范围广,是一个全球性的环境问题。重金属的大量积累会降低土壤中微生物的生物量和活性,甚至会影响微生物群落的结构和多样性。土壤微生物由于其高灵敏度和及时对环境因素作出变化而越来越多地被用作监控土壤质量的生物指标。现主要针对土壤中重金属污染在土壤微生物活性、生物量、微生物群落结构等方面的影响进行综述。结合现有研究因素综合考虑,对微生物生态学研究指标在重金属土壤修复领域进行展望,为重金属污染土壤研究提供更为全面的质量评价和有效指标。Soil heavy metal pollution is a global environmental problem because the pollution area is large and spreads widely. The accumulation of heavy metals will reduce the biomass and activity of microorganisms in the soil, and even affect the structure and diversity of microbial communities. Soil microbial properties are increasingly being used as biological indicators of soil quality due to their high sensitivity, and timely response to environmental factors. This article focuses on the impact of heavy metal pollution in soil on microbial activity, biomass, microbial community structure and other aspects. Combined with the comprehensive consideration of existing research factors, the indicators for microbial ecology will be prospected in the field of heavy metal soil remediation, providing a more comprehensive quality assessment and effective indicators for the study of heavy metalcontaminated soil.
