| 摘 要： | 本文运用地下水水质的模糊综合评判分析方法，选取地下水水质的主要影响因子，借助模糊逻辑T算子和协T算子，编制了有效的MATLAB计算机程序，绘制了隶属度函数的数学图形，对北方某水源地地下水水化学资料进行了模糊数学综合评价。评价结果表明，研究区采样点水质为Ⅰ、Ⅱ、Ⅲ级的占96．63％，大部分地下水水质较好，符合饮用水的要求。借助T和协T逻辑算子的模糊综合评判法评价地下水水质效果较好。

| Abstract: | A fuzzy synthetic evaluation of groundwater quality is demonstrated in this paper.After the determination of the predominant factors of water quality,the evaluation of groundwater quality of a wellfield in a certain area in northern China is carried out with a fuzzy mathematics method,with the aid of selecting fuzzy logic operators,compiling appropriate computer programming,and drawing curves of membership functions.The research results show that 96.63 percent of the water samples are below level III of the water quality standards.Most of the water samples are of good quality and fit the quality standards of potable water.Satisfactory results of groundwater quality evaluation can be obtained by using a fuzzy synthetic method with the aid of logic operators. |
