摘要
本文利用环境空气质量综合指数(Isum)对2016年-2020年福建省泉州市惠安县三个大气省控点的大气污染指标(SO_(2)、NO_(2)、O_(3)、PM_(10)、CO、PM_(2.5))进行分析,并探讨了气象因素对大气环境质量的影响。结果表明,惠安县2020年空气质量最好,对比2016年-2019年的同时期,空气质量大幅度提升;惠安县环境空气质量综合指数呈逐年下降的趋势,然而O_(3)的污染负荷率在所有因子中最高,并且五年间逐年升高,大气污染以O_(3)、PM_(10)和PM_(2.5)为主;6-10月空气质量较好,11月-次年4月空气质量较差;大气污染因子与气象条件的相关分析表明,温度和湿度越高、大气压越小,颗粒物和臭氧的浓度越低,有利于细颗粒物的扩散,因此在6-10月间,高温雨季惠安县污染较轻,臭氧污染可能是VOCs控制形成。
This paper analyzes the air pollution index(SO_(2),NO_(2),O_(3),PM_(10),CO,PM_(2.5))of three provincial air control points in Hui’an County,Quanzhou City,Fujian Province from 2016 to 2020,and analyzes the influence of meteorological factors on the air environment quality.The results show that the air quality of Hui’an County in 2020 is the best,compared with the same period of 2016-2019,the air quality is greatly improved;The comprehensive index of ambient air quality in Hui’an County showed a downward trend year by year.The pollution load rate of O_(3) was the highest among all factors,and it increased year by year in the past five years;The air quality is good from June to October,but poor from November to next April;The correlation analysis between air pollution factors and meteorological conditions shows that the higher the temperature and humidity,the lower the atmospheric pressure,the lower the concentration of particulate matter and ozone,which is conducive to the diffusion of fine particles.Therefore,the pollution of Huian County is lighter in the high temperature rainy season from June to October,and the ozone pollution may be caused by the control of VOCs.
