【摘要】：利用2013年6月至2014年5月长三角地区16个城市环境监测站点的臭氧小时浓度数据,分析长三角地区臭氧污染时空分布特征。结果表明,长三角地区臭氧浓度呈现夏季高、冬季低的季节变化特征。近海城市臭氧年均浓度较高,均高于60μg·m-3,内陆城市浓度较低,均低于50μg·m-3,而NO2分布与之相反,呈现夏季低、冬季高的季节变化特征。长三角地区四季臭氧日变化皆为典型的单峰型,夏季日最小值出现在06:00,其他季节推迟约1 h,日最大值均出现在15:00前后。夏季臭氧日变化的峰值浓度最大,为168μg·m-3,冬季臭氧日变化的峰值浓度最小,为85μg·m-3。
[Abstract]:Based on the ozone hour concentration data of 16 urban environmental monitoring stations in the Yangtze River Delta from June 2013 to May 2014, the temporal and spatial distribution characteristics of ozone pollution in the Yangtze River Delta region were analyzed. The results showed that the ozone concentration in Yangtze River Delta showed seasonal variation characteristics of high in summer and low in winter. The average annual ozone concentration in offshore cities is higher than 60 渭 g m-3, and the concentration in inland cities is lower than 50 渭 g m-3. The NO2 distribution is opposite, showing the seasonal variation characteristics of low summer and high winter. The seasonal ozone diurnal variation in the Yangtze River Delta is a typical single-peak type. The daily minimum value in summer appears at 06: 00, the other seasons are delayed by about 1 hour, and the daily maximum appears around 15:00. The maximum daily ozone concentration was 168 渭 g m ~ (-3) in summer and 85 渭 g m ~ (-3) in winter.
