为真实准确地反映地下水水质情况，分别介绍了F值法、内梅罗指数法、模糊综合评价法的基本原理，以2013年北京市某地区地下水枯水期6例水样为例，进行评价分析。结果表明：F值法使用便捷，结果直观，应用广泛，但会造成一定的不连续性，缺失Ⅲ类水。内梅罗指数法运算简洁，但过于突出最大污染因子，并且没有准确的地下水质量类别划分依据。模糊综合评价法虽然计算过程复杂，但是计算结果更加准确。经过3种方法的分析比较可以为实际工程中地下水评价方法的合理选择提供一定的技术指导。

In order to accurately reflect the condition of groundwater quality , this paper introduced the basic principle of three assessment methods including F-value , Nemero index and fuzzy comprehensive e-valuation method .Taking six types of groundwater sample collected from dry season of Beijing in 2013 for example ,it carried out assessment and analysis .The results show that F value method uses simple , results are intuitively displayed and widely applied , but it can cause some discontinuity and lack of class Ⅲwa-ter.The calculation method of Nemero index is simple , but it extremely emphasizes on the largest pollu-tion factor , and there is no accurate basis for groundwater quality category .Although the calculation process of fuzzy comprehensive evaluation method is complex , but the result is more accurate .The com-parison and analysis of three methods can provide technical guidance for the rational choice of evaluation methods of groundwater in practical project .
