摘 要：
通过对郑汴公路杏花营段和圃田段公路两侧两个断面39个土壤样品中6种重金属离子(铅、镉、镍、铜、锌、铬)数据采用双权重因子改进型模糊综合评判法进行评价分析,结果表明,评价区公路两旁300 m范围内的土壤环境质量大部分为二级到三级,公路北侧比公路南侧土壤重金属污染严重,杏花营断面的土壤环境质量比圃田断面的土壤环境质量差一些,这说明公路交通会对路旁土壤造成重金属污染,其污染程度受通车时间、主导风向、路旁防护措施等多方面因素的影响。

摘 要：
Based on fuzzy comprehensive evaluation method of double weight factors,this study aimed to analyze 6 kinds of heavy metals(Pb,Cd,Ni,Cu,Zn and Cr) in 39 soil samples on both sides of Zhengzhou-Kaifeng Highway between Xinghuaying and Putian.The results showed that: the main soil environmental quality was in the 2-3 grade within the scope of 300 meters on both sides of Zhen-Bian Highway;the heavy metal soil pollution on the north side of Zhen-Bian Highway was more serious than that on the south side;the soil environmental quality in Xing huaying cross was poorer than that in Putian cross.Then it came to the conclusion that the traffic causes heavy metal contamination to the soil on both sides of the highway,and the pollution level was determined by the opening of the time,the leading wind direction,the roadside protective measures and etc.
