| 摘 要： | 针对水质系统所表现出的复杂性和模糊性,采用基于模糊可变集合理论的模糊可变评价模型对地下水环境质量进行综合评价。通过科学地确定与地下水水质评价相关的各项指标处于区间值的相对隶属度和相对隶属函数,并根据二元比较模糊决策分析法计算出各指标的权重,最终得出地下水质量的级别特征值。同时,采用单项参数评价法和灰关联分析法对同一地下水水样进行水环境质量评价。结果表明,该方法不仅符合客观事物运动发展变化的自然辩证法原理,而且能够使评价结果更加合理、可信。

| Abstract: | According to the complexity and fuzziness of the water quality system,a Fuzzy Variable Set Model method is introduced for groundwater quality assessment.Different relative membership degree matrixes are obtained using different groups of model parameters and the reasonable weights of each index are calculated using comparison fuzzy decision analysis.Then the groundwater quality class is assessed correspondingly.Two different methods,single-parameter assessment method and grey relational analysis method,are ... |
