摘　　要：韦伯-费希纳定律是表明心理量和物理量之间关系的定律。基于此定律基本原理,以表征地下水质量的pH、NO3-、NO2-、NH3-N等水质参数作为评价指标,采用变异系数法确定各评价指标的权重,通过确定地下水质量等级与综合影响指数ki间的关系,综合评价地下水环境质量。本文以福建省东山县3个典型地下水水源地为实证案例,将应用韦-费模型的评价结果与传统的单因子指数法和内梅罗指数法评价结果进行比较,结果表明,韦-费模型应用于地下水环境质量的综合评价是科学合理的,且评价精度更高。Weber- Fechner（ W- F）Law describes the relationship between psychological quantity and physical quantity. Based on the law, some groundwater quality parameters, including pH, NO3- , NO2 - , NH3 - N and so on, were taken as the evaluating indicators, and the weight of each evaluating indicators were calculated by the variation coefficient method. The func- tional relation between the groundwater quality grade and the comprehensive effect index ki was determined, so the novel synthetic model for groundwater quality assessment was established. The three typical groundwater sources in Dongshan county of Fujian Province were selected as a demonstration cases. The results showed that as compared with two other classical evaluation methods, W - F Model provides reasonable and scientific assessments for groundwater quality with also more accuracy and precision.
