This paper reported soil microbial characteristics of Elsholtzia harchowensis-soil system in Lipu Copper mine tailings,Zhejiang Province,and correlations between the metal element contents of E. harchowensis and soil were also analyzed The results indicated that metal element contents of E. harchowensis in sequence were:Cu>Zn>Pb>Cd There were significant correlations in Cu contents between E. harchowensis and soil in Copper mined tailings region,and the next was in Zn contents Compared with the control,the E. harchowensis-soil system possessed obviously different soil microbial features:intensiver in microbial basal respiration strength,and higher microbial eco-physiological parameters Cmic/Corg and qCO₂,but lower in soil microbial biomass Biolog data showed that soil microbial community structure was obviously changed in the E. harchowensis-soil system,and much more consumed rapidly carbon sources,but the lower in the ratio of utilization compared with the control.
