摘　　要：依据国家大气质量标准,运用属性识别理论模型和变异系数的方法,以镇江市环保局2009年提供的原始数据为对象,对镇江市城区大气环境质量进行时空上的综合评价。结果表明,镇江市城区大气环境质量整体状况属于Ⅱ级(轻度污染);在时间尺度上第三季度各月份的大气环境质量最优,6月和10月具有较强的特点;空间尺度上丹徒监测站的大气环境质量较好,环境监测站较差。According to the national air quality standards and the original data provided by Zhenjiang Environmental Protection Bureau in 2009,the essay has made a synthetic evaluation on space and time scale about the quality of atmospheric environment in Zhenjiang City by selecting the SO2,NO2 and PM10 as evaluation factors and applying the methods of attribute recognition theoretical models and coefficients of variation.The results showed that：as a whole,the quality of atmospheric environment in Zhenjiang City belongs to low-grade pollution.On a time scale,each month of the third quarter has the best atmospheric environmental quality,especially June and October.On a space scale,the quality of atmospheric environment in Dantu monitoring station is better but environmental monitoring station is poor.
