摘　　要：鉴于水质综合评价中水质分级标准与监测样点的监测值之间存在模糊关系,将熵权法及置信度准则引入集对分析法中,以提高水质评价结果的可靠性,并应用于山东省大武地区地下水水质评价。根据2017年11月研究区29个检测站点的12个超3类水频率较高的水质指标实测值,进行水质模型求解,结果表明:以置信度准则替代最大隶属度准则作为水质评判标准,能有效避免水质分级“欠评价”和“过评价”;大武区域地下水水质为中等偏下,主要集中在侯皋-西夏一带。与最大隶属度准则的水质判别结果相比较,该方法更能真实反映评价水体的水质状况,具有水质信息综合全面、分级结果明确等优点,是地下水水质评价分级的一种可靠、合理的方法。In view of the fuzzy relationship between the water quality classification standard and the monitoring value of the monitoring sample point in the comprehensive evaluation of water quality,the entropy method and confidence criterion are introduced into the set pair analysis method,to improve the reliability of water quality evaluation results.and applied to the evaluation of groundwater quality in Dawu area of Shandong Province.According to the measured values of 12 Super 3 water quality indexes with high 29 detection sites in the November 2017 study area,the water quality model is solved,and the results show that the replacement of the maximum membership criterion with the confidence criterion as the standard of water quality evaluation can effectively avoid the“poor evaluation”and“over-evaluation”of water quality classification.Dawu area groundwater quality is moderately lower,mainly concentrated in Hougao-Xixia area.Compared with the results of water quality discrimination in the maximum membership criterion,this method can reflect the water quality status of water body more truthfully,has the advantages of comprehensive water quality information,clear grading results and so on,and is a reliable and reasonable method for groundwater quality evaluation and classification.
