摘　　要：根据2008—2016年济南市大气中SO_2的监测数据,分析了SO_2浓度的时间变化特征。结果表明,相比于2008年,2016年济南市SO_2年均浓度累计降低了约58%,年均浓度变化率为-0.008 mg/(m^3·a);济南市SO_2的月均浓度呈U型分布,在季节分布上呈现出冬季>春季>秋季>夏季的特征,采暖季SO_2浓度明显高于非采暖季。Characteristics of the temporal distribution of SO2 during 2008 to 2016 were analyzed at an urban site in Jinan. The results showed that mass concentration of SO2 in 2016 decreased about 58% compared to that in 2008, with an annual gradient of -0.008 mg/（m3,a）. Monthly aver-age concentration of SO2 displayed an U shape curve and the seasonal concentration order of SO2 was as follows： winter〉spring〉autumn〉summer. Significantly higher concentrations of SO2 were ob-served in heating season than that in non-heating season.
