摘　　要：通过对北运河香河段污灌区不同深度土壤重金属Cu、Pb、Zn、Cd含量的监测分析,评价污灌对土壤重金属含量造成的影响。结果表明,土壤中重金属含量和土壤理化性质、土壤深度以及污灌时间、污灌水重金属含量直接相关。By analyzing soil's contents of heavy metals,such as Cu,Pb,Zn and Cd in different depths,the effect of wastewater irrigation on the contents of heavy metals in soil is estimated.The results indicate that the accumulated contents of heavy metals in soil are related directly to the physicochemical properties of soil,the depth of soil,the time of wastewater irrigation and the contents of heavy metals in the wastewater.

关 键 词：污水灌溉 重金属
