摘要
针对目前采用内梅罗指数法评价地下水质量过程中存在的问题,考虑毒性金属的积累效应,引入权重值概念,对内梅罗指数法进行改进,并将改进前后2种方法应用于深泽县研究区地下水质量评价。结果表明:改进的内梅罗指数法可以在一定程度上消除极大值的影响,并提高毒理指标的影响程度,能够对地下水质量进行较为合理的评价。
In order to solve problems in evaluating groundwater quality with the Nemerow index method, the traditional Nemerow index method was improved by considering the accumulation effect of poisonous metals and introducing concept of weighting value. Two methods were used to evaluate groundwater quality in Shenze County. The results show that the improved method can eliminate the influence of the maximum number to a certain extent, increase the influence of the toxicant index, and lead to a reasonable evaluation result.
