Abstract
Lead pollution has negative impact on soil organism and soil physical-chemical character. This paper deals with the influence of lead on the intensity of soil respiration and the activities of dehydrogenase,catalase,urease,sucrase and microbial biomass carbon in vegetable soil. The results showed that after the application of leads with concentration of 20,100,500 mg · kg-1 dried soil, soil respiration of the highest concentration treated sample was strongly stimulated at the beginning but reduced slightly afterwards and it was higher than the lower ones,and the soil microbial biomass carbon was reverse. The activities of dehydrogenase.catalase and urease were enhanced at high concentration (500 mg·kg-1 )and depressed at lower concentration (20 mg·kg- 1)in vegetable soil at initial time. However, the soil sucrase was not significantly different between control (lead-free soil) and soil treated with lead.关键词
