In this paper, on the base of the investigation of open vegetable fields, facility vegetable fields, dry fields and paddy fields in Zhangjiagang region, Chang-Zhu-Tan region and Jing-Jin-Tang region, it found that heavy metal contents in most suburb fields were lower than the national 2nd standard of soil quality, but some heavy metal contents were higher than the local background values, which indicated that heavy metals accumulated in suburb fields. Heavy metal contents in vegetable fields were usually higher than paddy and dry fields due to the higher intensive input and use. The study in a special region of Chang-Zhu-Tan showed that it is difficult to reuse the fields after the soil was seriously contaminated. The variation coefficients of soil heavy metals in Jing-Jin-Tang region was higher than Zhangjiagang region.
