To understand the characteristics of soil heavy metal pollution in a planting area of Hengshui City, Hebei Province, 340 samples were tested and analyzed by using the ground accumulation index, Nemero comprehensive pollution index, potential ecological risk index and enrichment factor for comprehensive evaluation. The results showed that the average value of Igeo was less than 0, and the order of weakness to strength was As<Cr<Ni<Cu<Cd<Zn<Pb<Hg, among which the number of samples with Hg Igeo was 36.44%; the overall environmental safety was relatively low with PN; the exceedance rate of the total potential ecological risk index (RI) was 25.24%. 25.24%; the mean value of enrichment factor (EF) was less than 2, and the percentage of samples in the state of no to weak pollution was over 74.76%.
