摘要: 通过对安徽省芜湖市城市边缘区14个典型土壤采样点重金属As、Hg、Pb、Cd、Zn、Cr污染现状的调查与分析,以本地区自然土壤中重金属元素自然含量的平均值作为评价标准,分别计算出各调查区土壤单因子污染指数,应用对应分析技术,初步研究了芜湖市城市边缘区土壤重金属污染的空间分异特征。结果表明,芜湖城市边缘区土壤重金属污染已相当显著,且各区域间土壤重金属污染水平具有明显的差异。总体上看,鸠江、马塘、西江等样点较其他区域污染严重,各区域间Pb、Hg污染水平差异明显,但As、Cd、Zn、Cr污染水平差异不大。

Abstract: On the basis of the data on As, Hg, Pb, Cd, Zn, Cr heavy metal contents of soils sampled from 14 depth profiles in the periurban zone of Wuhu City, Anhui Provice, the status of soil pollution by heavy metals was studied by use of background contents of these elements under the natural soil condition. Meanwhile, the correspondence analysis method was applied to studing spatial differentiation of metal heavy pollution of the sample soils. The study indicates that on the whole the most of heavy metal existing in the sample soils quite resulted in obvious pollution. Different features of pollution were revealed in different regions. In general, the pollution is more serious in Jiujiang, Matang, and Xijiang area than in the other regions. It was also demonstrated that there was no significant spatial differentiation in contents of heavy metals in the soils, except Pb and Hg.

Key words: periurban, heavy metals, soil pollution, correspondence analysis
