摘　　要：运用土壤重金属污染评价领域中较多采用的几种评价方法,对我国某铀矿山土壤重金属污染进行评价,获得相关评价结果。在评价过程中发现各种评价方法自身存在的不足和缺陷,并提出确保评价结果准确性的建议和方法,从而为铀矿山土壤重金属污染的防控与修复提供技术与管理支持。Several methods which are often applied in the evaluation of soil heavy metal pollution were used to evaluate the soil heavy metal pollution of a uranium mine in China, including toxicity charac- teristic leaching procedure, single factor index method, geoaccumulation index method, Nemerow multi-factor index method, pollution load index method and potential ecological risk index method. It was found in the evaluation process that each method has its limitation. So, some suggestions and methods are put forward to ensure the accuracy of the evaluation results, thus providing technical and management support for the prevention and control and restoration of soil heavy metal pollution in uranium mine surroundings.
