| 摘 要： | 对呈贡县蔬菜土壤微生物种群数量和土壤重金属质量分数进行大田调查分析，结果表明，土壤微生物种群数量和微生物多样性指数变化较大，土壤微生物种群数量总体水平较高，但微生物多样性指数偏低，其中以细菌占较大的优势；土壤重金属对土壤微生物数量和微生物多样性均有一定的影响，其中土壤中Pb和Cu的质量分数与土壤微生物种群数量显著相关；土壤重金属综合污染指数与真菌／细菌个数比例、真菌／放线菌个数比例与微生物多样性指数均呈显著的指数相关。随着重金属综合污染指数的增加，微生物多样性指数呈指数式地迅速下降。

| Abstract: | Through field investigation, We have analyzed the soil microbial biodiversity status and concentration of Pb, Cd, Cu and Zn in soil. The results showed that the scopes of the amount of microbes and the indicator of microbial biodiversity were wide, in which the total amount of microbes was high and the bacteria was the main part, however the indicator of microbial biodiversity was lower. There were effects of Pb anf Cu on soil microbial biodiversity status, especially Pb and Cu. The comprehensive indicator of heavy metal had significant relationship to ratio of fungi-bacteria and ratio of fungi-actinomyces. The indicator of microbial biodiversity decreased rapidly with the increasing of comprehensive indicator of heavy metal. |
