利用内梅罗指数法模型评价地下水水质的探讨

A Discussion on Evaluating Groundwater Quality by Nemerow Index Method

文中阐述了评价地下水水质的内梅罗指数法和改进的内梅罗指数法。结合内梅罗综合指数法的原理,提出了水质评价标准的计算方法,水质的划分标准临界值的确定视参评指标项的具体情况而定。利用改进的内梅罗指数法和文中提出的评价标准对山西省某市的地下水水质进行了评价,并将评价结果与常用的内梅罗指数法的评价结果进行了对比。对比结果表明,两种方法具有比较明显的差异,文中采用方法的评价结果更为客观、合理。

In this paper,the common Nemerow Index Method and its imroved method for evaluating groundwater quality are introduced.By combining with the principle of these methods,a method to calculate evaluation criterion for water quality is put forward,and the determination of critical division values of water quality depends on the concrete water quality items chosen in this evaluation method.Using the improved Nemerow Index Method and evaluation criterion values presented by this paper,the groundwater quality of a certain city in Shanxi Province is evalua ted,and the evaluation result is contrasted with the result evaluated by common method.the contrast result shows that there are some obvious differences between the evaluation results of these two method,and the result evaluated by improved method is more objective and rational.
