Based on the soil environmental quality data collected through sampling and the soil environmental quality database established with the aid of GIS, the farmlands of Yongji City, Shanxi Province, were appraised by referring to the national criteria for evaluation of soil environmental quality. Results showed that among 18 sampling sites, 3 sites were not polluted yet,11 slightly polluted, and 4 moderately polluted, and that main pollutants in the region were F, Cl, Pb, Cd, As and DDT. Most of the vegetable fields met the criteria of NY/T391-2000 for production of green food and NY5010-2001 for production of hazard-free food and Cd, Pb, Hg, As and DDT were main pollutants in the sampling sites that fell short of the standard. The findings of the research has laid down a foundation for further strengthening soil environmental quality management and decision-making for remediation.
