通过阐述属性识别理论和变异系数，建立大气环境质量评价的属性训别理论模型，并参照国家大气环境质量标准（GB3095—1996），以镇江市环保局2009年提供的原始数据为对象，对镇江市大气环境质量进行空间上的综合评价。结果表明，镇江句容市的大气环境质量为I级（清洁），市区、扬中市和丹阳市的大气环境质量为Ⅱ级（轻污染）。同时，属性识别理论模型计算较为简单，评价客观；结合对主要污染物平均浓度变异系数的分析。使区域间的比较更为清晰，更能反映出真实情况。

Through describing the attribute recognition theory and coefficients of variation, an attribute recognition model of atmospheric environment quality assessment was established. This paper has made a synthetic evaluation on space scale about atmospheric environment quality of Zhenjiang City based on the original data provided by Zhenjiang Environmental Protection Bureau in 2009. The results showed that the atmospheric environmental quality in Jvrong is grade 1 （ clean）, while the atmospheric environment of urban district, Yangzhong and Danyang are grade 2 （ light pollution）. At the same time, the calculation of attribute recognition model is relatively simple and the evaluation is objective. The analysis of the average variation coefficients of main pollutants clarified the regional distinctions and presents a better reflection of the actual situation.
