The contents of heavy metals (Cr、Cd、Cu、Zn、Pb) of the greenhouse soils in Tai Lake region were analyzed and the polluted extents were evaluated according to the corresponding national standards. The results showed that the total contents of heavy metals (except Cr) were higher than the background values of Jiangsu Province. The total contents and available contents of heavy metals in 0~20 cm horizon soils were higher than in 20~30 cm horizon soils. The single factor pollution index and Nemorow multi-factor pollution index method were used to evaluate the soil pollution. According to the background values of Jiangsu Province and the Soil Environmental Quality Standard, the studied soils were evaluated at lightly-polluted and unpolluted degrees, respectively.
