In this paper , the grade of the urban environmental quality and the evaluating indexes and its eigenvalue are made as matter element , after normalizing the evaluate standard and surveyed data , the sutra field and controlled field and weight coefficient and relating degree are obtained , meanwhile , the model for comprehensive evaluating urban environmental quality is built up , then this model is applied to xuanzhou city for evaluating its environmental quality , the result shows that it accords to the result by the fuzzy method , and it is simpler method for evaluating the urban environmental quality
摘要将城市环境质量分级标准、评价指标及其特征值作为物元，对评价标准及实测数据进行归一化后，得到模型的经典域、节域、权系数及关联度，进而建立了城市环境质量的综合评价模型，并将该模型应用到宣州市环境质量的评价中，结果表明，与多级模糊综合评价法的评价结果相一致，是一种更为简单的城市环境质量综合评价法。
