摘　　要：在地下水质评价中,内梅罗指数法经常以各种修正方法的形式应用。根据文献进行总结,将各种修正方法总结为"引入权重法"和"引入函数法"两大类。随机抽取华北平原典型地区水样20例,运用两种方法进行水质评价,并对结果进行对比。结果表明,两种修正方法均比传统方法评价结果更为客观、准确。引入权重法强调了权重值最大几项指标的作用,更适合评价毒理性指标和重金属指标污染较突出的地下水。引入函数法的评价结果更为均匀合理,但并未根据污染造成后果的不同区分不同指标的作用,该方法更适合评价各项水质指标浓度较均匀的地下水。In the evaluation of groundwater quality,the Nemerow index method is often applied in various forms of correction methods.According to the literature,the various correction methods are summarized into two categories:"introducing weight method" and "introducing function method".20 cases of water samples were randomly collected from typical areas of the North China Plain.Two methods were used to evaluate water quality,and the results were compared.The results showed that the two methods are more objective and accurate than the traditional methods.The introducing weight method highlights the role of several compositions with the largest weight value,and is more suitable for evaluating groundwater contaminated by toxicological compositionsor heavy metal compositions.The result of the introducing function method ismore uniform and reasonable,but it can not distinguish the different compositions according to the different consequences of pollution.This method is more suitable for evaluating the groundwater with uniform concentration of water quality compositions.
