摘要
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 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.
