摘要
阐述了一种改进的属性识别方法,针对属性识别理论模型中置信度λ取值的主观性,提出了灰色接近度的概念,通过计算样品属性测度与理想模式属性测度之间灰色接近度的大小,判断样品所属类别。根据GB3095—1996《大气环境质量标准》,运用此模型对福州市2001—2008年的大气环境质量进行评价。
An improved model of attribute recognition method in atmospheric environmental quality assessment was studied.For the subjectivity of confident degree in the model of attribute recognition,a concept of grey close degree was proposed.Through calculating the grey close degree between sample and the ideal mode attribute,the sample＇s category was determined.Based on the Ambient Air Quality Standard（GB 3095—1996）,this model was applied to atmospheric environmental quality comprehensive assessment in Fuzhou,China, and atmospheric environmental quality in the period of 2001—2008 were assessed..
