摘　　要：重金属通过多种渠道进入土壤,对土壤环境造成不同程度的污染,通过深入了解土壤重金属的污染来源,可以更好的采取针对性的治理措施。土壤重金属污染问题日益突出,因此土壤重金属污染治理研究已刻不容缓。目前,国内外对土壤重金属污染评价方法的研究较多,针对不同的调查对象和研究目的,选取科学、合理的最优评价方法,准确评估土壤环境中重金属浓度的风险程度,可以科学指导土地规划利用,以及为土地风险管控和修复治理提供参考依据。Heavy metals enter the soil through many channels and pollute the soil environment to different degrees.By deeply understanding the pollution sources of heavy metals in the soil,we can take better targeted control measures.The problem of soil heavy metal pollution is becoming more and more serious,so it is urgent to study the treatment of soil heavy metal pollution.At present,there are many researches on the evaluation methods of soil heavy metal pollution at home and abroad.According to different investigation objects and research purposes,the suitable evaluation methods are selected to accurately evaluate the risk degree of soil heavy metal content,it can guide land use planning scientifically and provide reference for land risk management and restoration.
