摘　　要：为了研究近几年唐山市大气环境质量变化情况,深入了解污染大气的环境因子,通过运用模糊数学方法,选取SO2、NO2、PM10作为评价因子,参照大气环境质量标准,运用模糊综合数学方法计算了污染因子权重、权重分配系数和隶属度,研究其对唐山市大气环境质量的影响,并得出客观的评价。权重分析数据显示,2004年主要污染因子为PM10,2005—2010年主要污染因子则为SO2;经推理运算得出的综合评价结论为:唐山市总体大气环境质量为轻度污染(Ⅱ级),且空气质量在逐年好转。In order to study the quality of atmospheric environment change m recent years in Tangsnan, understanding the atmospheric pollution of the environment factor, selecting S02, NO2 and PM10 as evaluation factors, consulting the standards relevant to atmospheric environment and calculating the weight, distribution coefficients of weight, grade attachment of atmospheric pollution factor. The results of weight analysis indicated that the main pollution factor is PM10 in 2004 and S02 in 2005 to 2010. The results of comprehensive evaluation showed that atmospheric environment of Tangshan was mildly polluted （Grade Ⅱ ）, and it has been improved year after year.
