日照市环境空气质量特征分析

　　

[摘 要]根据日照市2020~2022年环境空气质量常规监测数据，分析日照市空气质量的年变化趋势、月变化规律以及污染特征等，得出结论：日照市2020~2022年空气质量综合指数逐年下降，环境空气质量逐年改善。PM_2.5月度变化呈“U”型分布，即夏秋季浓度低、冬春季浓度高。O₃月度变化呈“M”型分布，即夏秋季浓度高，冬春季浓度低。对综合指数贡献较大的前三项污染物为O₃、PM_2.5、PM₁₀，是制约日照市空气质量持续改善的主要污染物。加强臭氧和颗粒物协同治理是实现空气质量持续改善的重要途径。

[Abstract] According to the regular monitoring data of ambient air quality in Rizhao from 2020 to 2022, the annual trend, monthly variations and pollution characteristics of air quality in Rizhao City are analyzed. The conclusion is drawn that the comprehensive air quality index of Rizhao City decreased year by year from 2020 to 2022, and the ambient air quality improved year by year. The monthly variation of PM_2.5 shows a "U" type distribution, with low concentrations in summer and autumn, and high concentrations in winter and spring. The monthly variation of O₃ shows an "M" type distribution, with high concentrations in summer and autumn and low concentrations in winter and spring. Among the pollutants contributing significantly to the comprehensive index, O3, PM2.5, and PM10 ranked as the top three, which are the main pollutants restricting the continuous improvement of air quality in Rizhao City. Strengthening the collaborative management of ozone and particulate matter is an important way to achieve continuous improvement in air quality.
