摘　　要：抗生素抗性基因(ARGs)自2006年被认为是环境污染物之后,逐渐受到环境微生物领域的广泛关注。目前针对水体和土壤环境中的抗生素抗性基因的污染特征(种类、含量、变化规律等)及水平转移研究较多,尤其是抗生素环境残留造成的长期选择压力或者同时存在重金属污染的状态下,有利于抗生素抗性基因在不同菌株之间水平转移。抗性基因在环境中的传播增加了其本身对环境的威胁性,应该予以重视。本文针对环境中抗生素抗性基因的主要来源及分布情况、与重金属的相互作用以及基因水平转移、抗性基因的消除,这4个方面的研究进展进行综述,更全面地了解了抗生素抗性基因的污染特征。Antibiotic resistance genes（ARGs）were received increasing attentionsas emerging environmental contaminants,which were first defined in 2006.Existing researches are mainly about pollution property and dissemination of Antibiotic Resistance Genes（ARGs）in aquatic and soil environment. Actually environmental dissemination of ARGs are more important than itself and received more attention as environmental residues of antibiotic and heavy metal provided a selection pressure and promoted horizontal gene transfer. The review is mainly focused on source of antibiotic resistance genes, distribution,and the interaction with heavy metal, gene horizontal transfer, reduction of antibiotic resistance genes for further in researching contaminant feature.
