摘要
采用基于模糊可变集合理论的综合评判方法对地下水质量进行了等级评判,能科学合理地确定与地下水质量相关的各个研究指标处于级别区间的相对隶属函数,并根据指标重要性进行二元比较与量化确定出各个指标的权重,得出地下水质量的综合评价的级别特征值。实例表明,该方法计算简便、实用性强、可信度高。
Evaluation method based on variable fuzzy set theory is proposed to judge rank of groundwater quality. The method can scientifically determine relative membership functions of disquisitive indexes at level interval that relating to groundwater quality. According to importance of indexes, the weight values of indexes are determined by duality comparision and quantitative analysis. And then the rank feature values of evaluation for groundwater. Quality is obtained. The case study shows that the proposed method is simple to be calculated and is practicable to be used ,and as a result the evaluating achieves a high reliability.
