采集西安市二环内78处表层土壤样品，研究西安二环内城市表层土壤中Co、Cr、Cu、Mn、 Ni、Pb、Zn、V的空间分布特征，并采用相关分析、因子分析和聚类分析等多元统计方法探究西安市二环内城市表层土壤中8种重金属元素的来源。结果表明，西安市二环内表层土壤中Co、Cr、 Cu、Pb、Zn具有明显的高值带和高值区，而Mn、Ni、V在西安市二环内表层土壤中均匀分布，空间差异不大。多元统计分析表明，西安市二环内表层土壤中Co、Cr、Cu、Pb、Zn的累积主要受交通、工业生产，以及废弃物堆放等人类活动影响；Mn、Ni、V的累积则主要受成土母质影响。 |

The concentrations of Co,Cr,Cu,Mn,Ni,Pb,Zn and V in 78 urban topsoil samples collected from inside the Second Ring Road in Xi'an were measured by X-ray fluorescence spectroscopy.The spatial variability of eight heavy metals was identified by geostatistical analysis with the aid of GIS tools.And correlation coefficient analysis,factor analysis and cluster analysis were used to analyze the data and to identify the possible sources of these heavy metals.The multivariate analytical results show that the spatial variability of Co,Cr,Cu,Pb and Zn was obvious.The higher concentrations of five heavy metals were found in some high-value bands and high-value areas,while Mn,Ni and V were evenly distributed in space.The source analytical results show that the accumulations of Co,Cr,Cu,Pb and Zn were mainly related with transport activities,industrial activities and consumption residues,while Mn,Ni and V originated mainly from soil parent material. |
