Abstract: Abstract: Based on the investigation and sampling analysis of the soil environmental quality among 12 counties in Hebei province, this paper studied the content of soil heavy metals, such as Hg, As Pb, Cr and Cd., and their pollution , analyzed correlations of each heavy metal by using SPSS .Soil Environmental Quality Standard II and the methods of single factor pollution index and Nemerow integrated index were adopted to evaluate the soil environmental quality in the study area. The results showed that the value range of comprehensive evaluation in soil pollution was 0.085~0.991, The grade range was Ⅰ~Ⅲ,eight counties are determined grad Ⅰand one county is determined grad Ⅱ and three counties are determined grad Ⅲ. the heavy metal elements have no remarkable correlation, Except Pb and Cd. In summary, the results of assessment indicated that the soil quality was safety, the standard of content of soil heavy metals in study region can meet the requirements in Green Food Production Base.
