Abstract: In this paper,the ecological effect of HMs on soil microbes is reviewed,based on the analyses of the influence of HMs on soil microbial activities, populations and communities; the factors affecting HM toxicity on soil microorganisms; the criteria for evaluating HM toxicity on soil microorganisms;the resistance and adaptation of soil microorganisms to HMs; and the variety of HM toxicity.

Key words: Heavy metals (HMs), Soil microbe, Ecolgical effect, denitrification, irrigation, site preference value, stable isotope, nitrification, N2O
