摘　　要：利用2013年沈阳市环境空气监测点位臭氧监测数据,分析沈阳臭氧浓度变化特征,结合气象资料分析了其对臭氧浓度的影响。结果表明,沈阳市不同区域臭氧浓度变化特征基本一致。臭氧浓度日变化呈单峰趋势,最大值出现在14:00左右,最小值出现在6:00左右;臭氧浓度变化具有明显的季节特征,夏季臭氧浓度最高,春秋次之,冬季最低;臭氧浓度受温度、风速、湿度、能见度、天气情况影响,臭氧浓度变化是多因素共同作用的结果。Band on ozone monitoring data of Shenyang ambient air monitoring points in 2013 and meteorological data, analyzing the characteristic of the ozone concentration change in Shenyang. The results show that the trend of the ozone concentrations between different areas in one city was consistent. Diurnal variations of ozone concentrations exhibited with the characteristic of a single peak, and showed the peak often appeared at about 14：00 in the early afternoon and low concentrations about 6：00 during early morning. The seasonal variation is also clear that the least ozone concentrations is in winter, and the most in summer. Ozone concentration is influenced by temperature, wind speed, humidity, visibility and weather condition. Ozone concentration change is the outcome of combined action of multiple factors.
