摘　　要：随着污水灌溉面积的持续扩大,研究污水灌溉带来的重金属污染问题,特别是重金属污染物对土壤—作物系统的影响显得尤为重要。通过室内土柱模拟试验,以铅、镉两种常见的重金属为例,研究这两种重金属在不同土壤质地(砂土和砂壤土)条件下的运移积累规律。The area of sewage irrigation becomes more and more large.It is very important to study heavy mental pollution from sewage irrigation,especially the effcet of heavy mental on soil-crop system.Simulation soil column（indoor）were adopted to study the transportion and accumulation of lead and cadmium in soil under the condition of different soil texture（sandy soil and sandy loam）.

关 键 词：铅 镉 土壤 运移 积累
