摘　　要：利用污水灌溉农田既缓解水资源不足,也能促进水资源的可持续利用。不同灌溉水质会使土壤重金属发生不同程度的积累,给土壤环境质量和作物生长造成危害。在分析土壤中重金属来源以及重金属在土壤中形态、迁移、转化特点的基础上,重点分析了灌溉水质对土壤重金属含量特征的影响,并提出根据土壤不同重金属起始含量来制定灌溉水质有关相应标准有利于指导污水灌溉的合理进行。Using wastewater irrigation farmland not only alleviates water shortage,but protects the sustainable use of water resources.Water of different qualities make heavy metals accumulate to varying degrees in soil,which does harm to the quality of soil environmental and crop growth.Based on an analysis of soil heavy metals＇ sources and heavy metals＇ morphology,migration,the characteristics of transformation in soil,this paper analyzes the influence of irrigation water quality on heavy metals＇ concentration in soil.It will do good to guiding wastewater irrigation reasonably according to heavy metals＇ background values.
