摘　　要：在对湖南某退役铀矿山水环境重金属调查监测的基础上,应用内梅罗模型对水环境现状进行评价,从而为该铀矿退役治理效果评估提供参考依据,促进我国铀矿冶设施退役工作的发展。评价结果表明,就重金属污染而言,研究区水环境质量总体较好,但局部地段水环境质量较差;局部地段地表水中锰和镉含量严重超标是由开采软锰矿造成的,而与原铀矿山铀矿开采无关;沩水河水及地下水中锰含量普遍超标与本地区广泛产出软锰矿的地质背景条件有关;湖南某退役铀矿山退役治理效果较好。On the basis of a Hunan decommissioned uranium mine water environment investigation and monitoring of heavy metals, the application of Nemero model is carried on the present situation evaluation. It provides reference for the decommissioned uranium mine governance evaluation and promotes the development of China＇s uranium mining and metallurgy facilities decommissioning work. The evaluation results show that, in terms of heavy metal pollution, the water environmental quality in the study area are generally good, but the partial district water environment quality is poorer; Mn and Cd content in the partial district surface water exceeds bid badly, which is caused by mining soft manganese ore instead of the original in-situ uranium mining; The Mn content in Weishui River water and groundwater generally overweight and it is related to the geological background conditions of extensive soft manganese ore output in this region. The treatment effect of the decommissioned uranium mine in Hunan is good.
