摘    要:以土壤酶活性和微生物数量作为生态毒理指标,通过模拟试验,比较分析多环芳烃菲和重金属镉单一与复合污染对土壤微生物的生态毒理效应.结果表明,菲和镉复合污染对土壤蔗糖酶、脲酶和脱氢酶均具有协同抑制作用;而对磷酸酶和微生物的数量具有拮抗抑制作用.菲和镉复合污染及菲单一污染对土壤微生物的活性抑制率从大到小依次为:放线菌>真菌>细菌;镉单一污染则为:真菌>细菌>放线菌.

关 键 词:    复合污染  土壤微生物  生态毒理效应

Abstract:The effects of phenanthrene and cadmium (Cd) combined and simplex pollution on soil enzyme activities (sucrase,urease, dehydrogenase, phosphatase) and microbial community were studied by simulative experiment The results showed that there existed synergistic inhibiting effect on sucrase, urease and dehydrogenase and antagonisticinhibiting effect on phosphatase and soil microbial community under the compound pollution of phenanthrene and Cd. The order of inhibiting rate of soil microbial activity under phenanthrene and Cd combined pollution and phenanthrene simplex pollution were proved to be: actinomyces>fungi>bacteria; the order under Cd simplex pollution is fungi>bacteria>actinomyces.
Keywords:phenanthrene  cadimum  combined pollution  microbe  ecotoxicological effect
