摘    要:利用熵权法并结合属性识别理论,建立了熵权-属性识别模型。采用地表水环境质量标准(GB3838—2002)作为依据,选用7个影响因子作为评价指标,利用熵权法确定各评价指标的权重以计算综合属性测度区间,应用置信度准则和评分准则对地表水质量进行属性识别。实例研究表明,该模型能有效地解决地表水质量评价的问题,评价模型采用熵权法确定权重,避免了权重确定中的主观性和随意性,保证了评价工作的客观性和准确性。

关 键 词:熵权  属性识别模型  地表水  评价

Abstract:Attribute recognition theoretical model is set up on the basis of entropy weight method. Based on the surface water environment quality standards (GB3838 -2002), seven indices are chosen as the evaluation indices, the synthetic attribute measurement interval is calculated by the entropy weight, the confidence criterion and the score criterion are used to recognize the surface water environment. The result from case study indicates that the model is effective to evaluate surface water environment. Moreover, using entropy weight, the model could avoid subjectivity and arbitrary in the process of determination index weight, and ensure objectivity and accuracy of the evaluation.
Keywords:entropy weight  attribute recognition model  surface water  assessment
