| Abstract: |
| This experiment explored the relationship between soil organic matter content and the stability of lead contaminated soil, and studied the effects of different levels of lead contaminated soil amended by adding organic matters on the microbial community structure and diversity using the phospholipid fatty acid(PLFA) analysis method. The results showed that the bacteria are dominant in lead contaminated soil microbial community. The less lead contamination and the less organic matter content in the soil, the lower soil microbial diversity it will have, whereas the diversity is higher. G- and fungus with organic content and soil stability are significant positive correlations(P<0.01); the ecological stability of lead contaminated soil can be enhanced by improving soil organic matter content. |
