| 摘 要： | 选取郑州市自然条件类似但工业化、城镇化水平差异的市区、中牟县城和韩寺镇,测定土壤中Pb,Cd,Zn,Cr,Cu,Ni 6种重金属元素含量,采用内梅罗综合指数和加权统计分析法进行重金属污染评价,并通过灰色斜率关联度分析方法初步分析了城镇土壤重金属污染的主要人为活动源因素.结果表明,研究区土壤主要污染元素为Pb,Cd,Zn和Cr;土壤Pb污染主要与交通、工业有关,Cd污染与城镇建设、工业有关,Zn污染与居民日常生活和工业有关;各级城镇土壤均发生不同程度的重金属污染,综合污染大小次序为郑州市区中牟县城韩寺镇.

| Abstract: | The heavy metal pollutions are investigated in different ranking urban soils with the example of Zhengzhou City,Zhongmu County and Hansi Town,which sharing similar natural conditions but different levels of urbanization and industrialization.The contents of Pb,Cd,Cu,Zn,Cr and Ni in soils are determined.Applying Nemerow integrated index and method of weighted statistcal analysis,pollution of heavy metals is evaluated.Then,several human driving factors influencing heavy metal pollutions in urban soils are ana... |
