摘要：

为了探索重金属污染与土壤微生物学指标的内在联系,选取芜湖发电厂灰渣场的土壤,研究其微生物的分布,并对重金属耐性菌株进行筛选。结果表明:灰渣场周围土壤中的细菌和真菌数量较多,而放线菌数量较少,并且采样点距离排污口越近,微生物的数量越少。镜检发现重金属铜和铅耐性菌株均为单一的短杆状真菌,对铜和铅最大耐受浓度分别为70和200mg·L-1;重金属镉耐性菌株筛选出的菌落并非单一菌落,最大耐受浓度为10mg·L-1。

摘要：

In order to explore the inner link of metal contamination and soil microbiological indicators.The soil of ash field of power plant was collected,microbial distribution and screening of tolerance strains to heavy metal was studied.The results showed that bacteria and fungi were more than actinomycetes,microbial amount was decreasing with the distance from pollution spot.The tolerance strains to heavy metal Cu and Pb were single,bacilliform fungi through microscope.Furthermore,the biggest tolerance concentration was 70and 200mg·L-1;the tolerance strains to Cd was not single and the biggest tolerance concentration was 10mg·L-1.
