摘　　要：基于WRF-CAMx/OSAT空气质量模拟平台,对2019年4月和2019年9月厦门市洪文和鼓浪屿两个国控空气质量监测点的O_(3)数值进行模拟解析,用以分析厦门市春夏季臭氧污染来源,结果表明厦门市臭氧污染区域性非常强,区域传输是厦门市臭氧的最主要来源,从省内区域贡献看,春季,漳州市对厦门市日间臭氧小时浓度贡献为46.6%,厦门市本地排放贡献为16.2%,泉州市的贡献为11.7%,福州市的贡献为9.6%,其他地市贡献均在5%以下。秋季,泉州市对厦门市日间臭氧小时浓度贡献35.4%,厦门市本地排放贡献为31.2%,漳州市贡献10.5%,福州市贡献9.8%,其他地市贡献均在5%以下。Based on WRF-CAMx air quality model and OSAT module,the ozone(O_(3))value of Hongwen and Gulangyu national air quality control station in April 2019 and September 2019 was simulated and analyzed to characterize the sources of O_(3) pollution in Spring and summer in Xiamen.The results showed that the major source contributor to O_(3) was long distance transportation.The local source had little contribution to O_(3) concentration in Xiamen in spring,but relatively larger contribution in autumn.In terms of regional contribution within the province,in spring,local source was the second contributor(16.2%)to the daytime hourly concentration of O_(3) in Xiamen,which was significantly lower than the transportation from Zhangzhou(accounting for 46.6%),and followed by Quanzhou(accounting for 11.7%)and Fuzhou(accounting for 9.6%)and other cities(accounting for less than 5%in each).In autumn,the situation changed.Local emission was still the second contributor(31.2%)to the daytime hourly concentration of O_(3) in Xiamen,which was slightly lower than the transportation from Quanzhou(accounting for 35.4%),and followed by Zhangzhou(accounting for 10.5%)and Fuzhou(accounting for 9.8%)and other cities(accounting for less than 5%in each).
