摘　　要：模糊综合评价法能反映水质评价中的模糊概念,是客观评价目标水质的一种常用水质评价方法。但在传统的模糊综合评价法中,多采用"超标法"计算权重,为了避免超标法计算权重的不合理之处,笔者分别用"改进超标法"和"层次分析法"计算评价因子的权重,以中卫美利纸业工业园区四个监测井的水质监测资料为例,采用改进模糊综合评价法做出了生活饮用水质量评价,并对比分析评价结果,提出了新的权重计算方法来实现对传统模糊综合评价法的改进。The fuzzy comprehensive evaluation method can reflect the fuzzy concept in water quality evaluation,and is a method that can evaluate objective water quality.However,in the traditional fuzzy comprehensive evaluation method,the weights are usually calculated by 'overweight method',in order to avoid the unreasonable weight calculation from the 'overweight method',the paper used the 'Improved Overweight Method' and the 'Analytic Hierarchy Process' to calculate the weights of the evaluating factors.Taking the monitoring data of groundwater quality in Meili paper industry zone of Zhongwei City for example,the paper adopted the improved fuzzy comprehensive evaluation method to carry out the drinking water quality evaluation,and compare and analyze the evaluation results.It put forward a new methodology to improve the traditional fuzzy comprehensive evaluation method for water quality evaluation.
