摘　　要：本文利用两种不同方法在传统的内梅罗污染指数法的基础上引入权重,对传统的内梅罗污染指数法进行改进,并对鞍山市境内的省级重点水质站断面进行水质评价,以了解不同改进方法在实际应用中对评价结果的影响及目标断面的综合水质情况。结果表明,利用参评指标污染指数最大值和权重最大的参评指标污染指数,代替传统内梅罗指数计算式中单一的参评水质指标污染指数最大值的方法,更能科学地显示目标水域水质情况。This study introduces weights into the traditional Nemero Pollution Index method using two different approaches to improve it.It evaluates the water quality of provincial key water quality stations in Anshan City and examines the impact of different improvement methods on the evaluation results and the comprehensive water quality of target sections.The results indicate that using the maximum pollution index of participating indicators and the maximum pollution index of participating indicators with the highest weight to replace the traditional method of calculating the maximum pollution index of single participating water quality indicators in the Nemero index formula can more scientifically reflect the water quality situation of the target water body.
