摘　　要：目前,地下水环境质量评价常采用两种方法,即单因子指数法和内梅罗指数法,内梅罗指数法可用于计算地下水的综合污染指数。本文以亳州市主城区为例,采用2种方法对2022年地下水型饮用水水源地的水质进行评价。评价结果表明,单因子指数法可以直观地反映超标项目,但容易过度突出某一指标的贡献;内梅罗指数法可以兼顾突出指标和其他指标,充分体现水质变化的连续性,因此评价更为合理。At present,two methods are commonly used for evaluating groundwater environmental quality,namely the single factor index method and Nemero index method,and Nemero index method can be used to calculate the comprehensive pollution index of groundwater.Taking the main urban area of Bozhou City as an example,this paper uses two methods to evaluate the water quality of groundwater based drinking water sources in 2022.The evaluation results indicate that the single factor index method can intuitively reflect projects that exceed the standard,but it is easy to overemphasize the contribution of a certain indicator;Nemero index method can balance outstanding indicators and other indicators,fully reflecting the continuity of water quality changes,making the evaluation more reasonable.
