摘　　要：为深入分析土壤重金属污染问题,建立了一种适用于碱性土壤性质的重金属污染风险预测模型,并对所建模型进行场地应用及风险评价结果分析。对单项和内梅罗指数法的评价方法进行优化,对土壤的酸碱性、含水量、重金属污染物含量以及污染种类等影响因素进行综合分析,并对分析评价结果和新建模型评价结果进行比对,结果表明新建预测模型与土壤重金属污染分析结果基本一致,为土壤重金属污染治理和修复提供了新思路。In order to deeply analyze the problem of soil heavy metal pollution,a heavy metal pollution risk prediction model suitable for alkaline soil properties was established,and the site application and risk assessment results of the built model were analyzed.The study optimize the evaluation methods of single item and Nemerow index method,comprehensively analyze the influencing factors of soil acidity and alkalinity,water content,heavy metal pollutant content,and pollution types,and compare the analysis and evaluation results with the evaluation results of the new model.The results show that the new prediction model is basically consistent with the results of soil heavy metal pollution analysis,which provides a new idea for soil heavy metal pollution control and restoration.
