摘要: 空气污染与人类活动、城市扩张等因素密切相关。本研究中利用中国区域1 km分辨率PM2.5数据，分析浙江省与温州市2000~2020年PM2.5浓度空间分布特征、年均值分布特征；应用Mann-Kendall检验法分析PM2.5浓度年平均值变化趋势。结果表明，浙江省与温州市2000~2020年PM2.5浓度均呈现先升高再降低的趋势，且PM2.5浓度年均值的降低和“十二五”国家规划高度相关；浙江省与温州市趋势突变点都出现在2017年，温州市PM2.5浓度年平均值的变化趋势显著大于浙江省。该研究有助于了解和掌握我国大气环境质量的演化发展情况，为区域的空气污染防治、城市发展规划提供参考借鉴。
Abstract: Air pollution is closely related to human activities, urban expansion and other factors. In this study, the spatial distribution characteristics and annual average distribution characteristics of PM2.5 concentration in Zhejiang Province and Wenzhou City from 2000 to 2020 were analyzed using the 1 km resolution PM2.5 data in China; Mann-Kendall test was used to analyze the annual average change trend of PM2.5 concentration. The results showed that the PM2.5 concentration in Zhejiang Province and Wenzhou City increased first and then decreased from 2000 to 2020, and the reduction of the annual mean PM2.5 concentration was highly related to the “Twelfth Five Year Plan”. The trend mutation points of Zhejiang Province and Wenzhou City both appeared in 2017, and the change trend of annual average PM2.5 concentration in Wenzhou City was significantly greater than that in Zhejiang Province. This study is helpful to understand and master the evolution and development of atmospheric environment quality in China, and provide reference for regional air pollution prevention and urban development planning.
