摘　　要：以大庆市SO2、NO2和PM10年平均浓度值作为环境空气质量评价指标,基于模糊综合评价法构建了评估模型,对大庆市环境空气质量现状进行分析。2006年-2016年,大庆市SO2和NO2年平均浓度值呈上升趋势,PM10年平均浓度值变化趋势平稳;SO2和PM10年平均浓度值污染贡献率呈下降趋势,NO2年平均浓度值污染贡献率呈上升趋势,PM10年平均浓度值污染贡献率超过50%,占主导地位。环境空气污染主要来源于能源消耗、扬尘、汽车尾气和气候因素等4个方面。The average annual concentration of SO 2, NO 2 and PM 10 in Daqing City were taken as the evaluation index of ambient air quality and an evaluation model was constructed based on the fuzzy comprehensive evaluation method. The current situation of ambient air quality in Daqing City was analyzed in this paper. From 2006 to 2016, the average concentration of SO 2 and NO 2 in Daqing City showed an upward trend, and the average concentration of PM 10 showed a steady trend;the contribution rate of SO 2 and PM 10 showed a downward trend;the contribution rate of NO 2 showed an upward trend. The contribution rate of PM 10 was more than 50%, which occupied a dominant position. The environmental air pollution mainly comes from four aspects including energy consumption, dust, automobile exhaust, and climate factors.
