Space Characteristics Analysis of Heavy Metals of Surface Soil in Huainan Mine Restoration Area, Anhui Province, China

摘要

0～20em soil was sampled from a coal mine of Huainan City Restoration Area and content of five heavy me0tals(Cu,Cr,Ni,Pb and Cd) in the soil was measured.According to the results,ordinary kriging method was used for spatial analysis of the distribution of soil heavy metals of the study area.The results showed that the four heavy metals such as Cu,Cr,Ni and Pb were standard one or two of the soil environmental quality standard.Cd distribution was more complex,soil standard one,two and three mixed intersection.The concentration of the some areas was even more than standard three.
