摘　　要：利用台州市2019~2022年环境空气质量监测数据,分析台州市空气质量的年变化情况、空间特征、逐月变化情况、污染物特征,结果表明:经过精准治理和科学治理,2019~2022年,台州全市的环境空气质量总体上处于不断改善提升的状态;其他县市的环境空气质量普遍高于台州市城区;市区的空气质量在夏季污染程度较低,空气质量较好,冬季污染程度略高,空气质量相对较差。PM_(2.5)月均值浓度变化呈现U型分布,在夏季达到浓度低点区域。O_(3)月均值变化大体呈“M”型,即夏、秋季浓度高,冬、春季浓度低,逐渐代替PM_(2.5)成为首要污染物;占比位于前三项的污染物分别是O_(3)、PM_(2.5)、PM_(10),台州市区的空气质量主要受O_(3)与PM_(2.5)污染影响。Based on the monitoring data of ambient air quality in Taizhou from 2019 to 2022,the variation trend of ambient air quality in Taizhou such as the annual changes,the spatial characteristics,monthly changes and the pollutant characteristics were analyzed in this study.The results showed that,the air quality of Taizhou has improved significantly though the Scientific and precise treatment.The ambient air quality in other counties and disticts of Taizhou is generally better than that in the urban areas.The urban areas of Taizhou have a low level of air pollution in the summer and a high level of air pollution in the winter.Monthly average concentration of PM_(2.5) presents a U-shaped trend of low concentration in summer.Monthly average concentration of O_(3) presents a M-shaped trend of high concentration in summer and autumn and low concentration in winter and spring.O_(3) has gradually overtaken PM_(2.5) to become the primary air pollutant.The air quality in urban areas of Taizhou is mainly affected by pollution O_(3) and PM_(2.5) as the top three proportion of pollution are relatively O_(3),PM_(2.5) and PM_(10).
