The investigation was conducted on soil nutrients and heavy metals contents in 0-20 cm soil of greenhouse vegetables from ten districts in Tianjin.The indexes of six soil chemical properties were hydrolyzed nitrogen(AN)，available phosphorus(AP)，available potassium(AK)，organic matter(SOM)，total salt (Salt)content and pH.The eight soil heavy metals were Cd，Pb，As，Hg，Cr，Cu，Zn and Ni.There were significant differences in AK，SOM and pH among districts.The average SOM of the ten districts in Tianjin was 35.11 g/kg.The average Salt content was 2.55‰.The soil in ten regions was alkaline，with an average pH of 7.91.The main heavy mental pollution was Cd in Tianjin，and the other seven heavy metals were under control.Pearson correlation analysis showed that Salt content in greenhouse vegetable soil was positively correlated with AN，AP，AK and SOM contents，indicating that the excessive application of fertilizer increased soil salinization.Soil pH was negatively correlated with AN and AP contents，indicating that increasing fertilization could reduce soil pH.The correlation analysis between planting years and fourteen indexes showed that local water and fertilizer investment and planting method could reduce soil salinity and pH，meanwhile the attention should be paid to the accumulation of soil heavy metals.
