Soil basal respiration,soil biomass carbon,metabolic quotient are important indexes of soil microbiological,they relate to physical-chemical character of soil.The dehydrogenase activity is the important sensitivity index of microbial community and activity on soil.Different added lead concentration ranging from 200 mg/kg to 1 200 mg/kg effect on soil basal respiration,soil biomass carbon,metabolic quotient and dehydrogenase activity.The experiment was studied in house incubated soil samples.The results showed as follows: soil biomass carbon decrease with extend incubated times.Soil basal respiration was increased with increased concentration of lead.Soil metabolic quotient were changed with different incubated time.Soil dehydrogenase significantly decrease under lead stress.The correlation analysis indicated that soil added lead content different correlation with soil biomass carbon,dehydrogenase activity in different incubation times.
