This paper analysed heavy metal content in soil samples of different depth from the eastern,analyzed the relation between the concentration change of heavy metals in soil,provided the scientific evidences for effluent irrigation,solving the problems of water in effluent irrigation areas and environmental impact assessment.
通过对某污灌区土壤中重金属的测试,分析了不同土层剖面深度土壤样品中重金属Cr、Cu、Cd、Pb元素含量,揭示了重金属在垂直方向上的浓度梯度变化趋势与土壤性质的内在联系,为指导污水灌溉,解决污灌区缺水的现状,以及开展环境影响评价工作提供了科学依据。

We analyzed and evaluated contents of several heavy metals(Cr,,Cu,Cd,Pb)in soil samples at different depths collected from eastern Inner Mongolia receiving effluent irrigation.
结果表明,随着土层加深重金属含量减少,经过十几年的污水灌溉,当地的地下水目前没有受到污染,这说明重金属在土壤中的迁移具有随着土层厚度增加而减弱的趋势。

补充资料：漫灌
漫灌
flood irrigation
mangUan漫灌(flood irrigation)灌溉时，水在地面上四处漫流，形成水层，并逐渐以重力作用浸润土壤的一种灌溉方法。这种方法灌水不均匀，水量浪费很大，并使土壤结构破坏，养分流失，使地下水位上升导致土壤盐碱化和沼泽化。目前漫灌仅用于灌概天然草场、引洪淤地，有时也用于储水灌溉。 (朱风书)
