摘　　要：利用2017—2019年银川都市圈贺兰山东路、贺兰山马莲口、石嘴山沙湖旅游区、吴忠教育园区、宁煤烯烃的NO、NO_(2)、NO_(X)、O_(3)质量浓度资料,对不同功能区臭氧(O_(3))污染及超标特征进行了研究。结果表明:①近3年,贺兰山东路、贺兰山马莲口、沙湖旅游区O_(3)质量浓度“先升后降”,吴忠教育园区O_(3)质量浓度升高,而宁煤烯烃O_(3)质量浓度“先降后升”。②各站点平均O_(3)质量浓度最高值出现在6—7月,其中贺兰山东路O_(3)质量浓度值最大,为215.4μg/m^(3),教育园区O_(3)质量浓度值最小,为160.9μg/m^(3)。③各站点O_(3)质量浓度的日变化呈单峰型分布,一天中O_(3)质量浓度最高值出现在16:00—17:00,最低值出现在08:00前后。④O_(3)质量浓度超标主要集中在5—8月;O_(3)质量浓度累计超标时数银川最多,其次为石嘴山,最少为宁东;交通居民混合区贺兰山东路O_(3)最高时均值和超标率较大,吴忠O_(3)超标平均质量浓度较高。Based on the concentration data of NO,NO_(2),NO_(X) and O_(3) from Helan Mountain East Road,Helan Mountain Maliankou,Shizuishan Shahu tourist area,Wuzhong Education Park and Ningcoal olefins in Yinchuan metropolitan circle from 2017 to 2019,the characteristics of ozone(O_(3))pollution and overstandard in different functional areas were studied.The results showed that①In recent 3 years,O_(3) concentration in Helan Mountain East Road,Helan Mountain Maliankou,Shahu tourist area first increased and then decreased,O_(3) concentration in Wuzhong Education Park increased,and Ningcoal olefins first decreased and then increased.②The highest average O_(3) concentration occurred in June and July,among which the maximum value of Helan Mountain East Road was 215.4μg/m^(3),and the minimum value of Education Park was 160.9μg/m^(3).③The diurnal variation of the ozone was unimodal type distribution,the highest ozone concentration appeared between 16:00 and 17:00 and the lowest around 8:00.④The O_(3) exceeding standard was mainly concentrated in May and August;Yinchuan had the highest cumulative hours of exceeded ozone,followed by Shizuishan and Ningdong at least.In the mixed area of traffic residents,the highest average time and the exceeding standard rate of O_(3) in Helan Mountain East Road were relatively large,while the exceeding standard average concentration of O_(3) in Wuzhong was relatively high.
