| 摘 要： | 鉴于物元可拓评价模型存在关联函数计算上的局限性，提出通过改进物元可拓评价模型的构造过程进行水质评价，并引入层次分析法和熵权法计算评价指标的综合权重以避免指标权重的绝对主观性和绝对客观性，建立了基于综合权重和改进物元可拓法的地下水水质评价模型，并从感官、一般化学、毒理学3个方面构建了地下水水质综合评价指标体系。将该模型应用于平度市古岘镇的地下水水质评价，并与综合评分法和属性识别法的水质评价结果进行比较分析。结果表明：该模型评价结果与其他两种方法评价结果的相同率均达70%，即使评价结果不同处的差异也基本在1个等级范围之内；而综合评分法和属性识别法评价结果的相同率仅为50%，且评价结果不同处的差异最大可达3个等级。

| Abstract: | In view of the deficiency of matter-element extension evaluation model in calculating correlation function, the authors built a groundwater quality evaluation model to improve the matter-element extension evaluation model, through using analytic hierarchy process and entropy method to work out comprehensive weight of every evaluating index,so as to avoid the absolute subjectivity and absolute objectivity of the index weight, and built a comprehensive evaluation index system of groundwater quality based on sensory, general chemistry and toxicology. This model was used to evaluate the groundwater quality of Guxian Town in Pingdu, and the application results of this model were compared with those obtained from integrated evaluating method and attribute recognition method. The result of this evaluation model is 70% the same as the result of the other two assessment methods; and the difference between them is basically within the same level; while between the other two methods, the result of one is only 50% the same as that of the another one, and the difference between these two assessment results can reach up to three levels. |
