摘　　要：为研究四川省成都市近郊蔬菜地土壤重金属污染情况,以成都市近郊主要蔬菜地为调查对象,采集了30个土壤样本,对土壤中重金属元素镉、铅、铜、锌、镍、铬的含量进行测定,结合国家相关土壤质量标准,采用单项污染指数法和内梅罗综合污染指数法对土壤重金属污染状况进行分析和评价。结果表明:该区域蔬菜地土壤存在轻度镍、镉、铜污染,且镍的污染程度最严重,锌、铬存在潜在危害。In order to study the degree of heavy medal pollution at the vegetable bases in Chengdu suburban area of Sichuan Province, 30 soil samples were collected and measured on condition of the heavy medal elements： cadmium, lead, copper, zinc, nickel, and chrome. After an- alyzing and assessing by adopting both the single factor index method and Nemerow multi-factor index method, findings are as follows： there is a slight pollution of copper, nickel, and chrome , among which nickel pollution is the worst and there is a potential danger in zinc and chrome elements.
