To appraise soil environmental quality, the study was conducted in the suburb of Zhengzhou city. The concentrations of heavy metals Cd, Hg, Pb, As and Cr in the topsoil samples were analyzed, and the soil environmental quality on the base of different criteria were evaluated by single factor index and Nemerow multi-factor index method respectively. Furthermore, the spatial variability of soil heavy metals pollution was researched with Kriging interpolation method. The analytical results indicate that the variability of soil heavy metals has the feature of Hg> Cr> Pb> As > Cd; all the study area meet the demand of non-polluted vegetable production base environment, majority of study area is appropriate to development the green food production base, and only about half of it suit for the development of organic agricultural production base. So it could provide a credible groundwork and assistant decision-making for agricultural development planning and other relative manage department to protect cultivated land and realize the sustainable use of soil resources.
