摘　　要：为解饶阳县蔬菜大棚土壤中铅、镍、铜、锌四种重金属的污染问题,本文以五公镇、留楚乡(不包括合方村)、合方村三个蔬菜大棚种植区土壤为研究对象,采用单项污染指数法、内梅罗综合污染指数评价法和潜在生态危害指数法进行综合评价。研究结果表明,五公镇、留楚乡、合方村蔬菜大棚内土壤重金属单项污染指数由低到高为Cu<Zn<Pb<Ni;三个研究区的污染等级都是轻度污染;五公镇的潜在生态危害程度为中度,留楚乡、合方村潜在生态危害程度为轻度。In order to solve the four heavy metals pollution of lead,nickel,copper and zinc in the vegetable greenhouse soil in Raoyang County,this paper takes the soil of three vegetable greenhouse planting areas in Wugong Town,Liuchu Township(excluding Hefang Village)and Hefang Village as the research object,and uses single pollution index method,Nemeiro comprehensive pollution index evaluation method and potential ecological hazard index method for comprehensive evaluation.The research results show that the soil heavy metal pollution index in vegetable greenhouses in Wugong Town,Liuchu Township,and Hefang Village ranges from low to high as Cu<Zn<Pb<Ni;the pollution levels of the three study areas are all light pollution;the potential ecological hazard of Wugong Town is moderate,and the potential ecological hazard of Liuchu Township and Hefang Village is mild.
