摘　　要：以闽三角城市群(厦门、漳州和泉州)为研究区域,以PM10质量浓度为大气颗粒物指标,根据世界卫生组织的标准定义大气污染事件,研究闽三角城市群大气污染事件发生频次及其相应大气颗粒物的时空特征,及影响大气颗粒物浓度的气象因素。结果表明:①闽三角城市群大气污染事件发生频次及其相应PM10浓度的季节变化的总体特征为:夏、秋季较低,春、冬季较高。②闽三角城市群大气污染事件发生频次及其相应PM10浓度总体的空间差异表现为泉州>漳州>厦门,但城市内部空间差异较大。③漳州市冬季污染事件中PM10浓度受降水量影响显著;影响厦门市PM10浓度的气象因素主要为降水量和气温;对泉州PM10浓度影响显著的气象因素是风向和湿度。Atmospheric particulate matter has become a major air pollutant affecting urban air quality and human health.Taking Fujian triangle urban agglomeration as the research area,PM10 concentration as the index of atmospheric particulate matter,air pollution events are defined according to WHO standards.According to the frequency of air pollution events,the concentration of PM10 and the meteorological factors affecting the concentration of atmospheric particulate matter in urban agglomerations were studied.The results showed that the frequency and concentration in Fujian triangle urban agglomeration were lower in summer and autumn,higher in spring and winter.The spatial difference of the frequency and the concentration in the area showed that Quanzhou was larger than Zhangzhou and Xiamen.There was great difference in urban interior space.The PM10 concentration in Zhangzhou was significantly affected by precipitation in winter.The main meteorological factors affecting concentration in Xiamen were precipitation and temperature.Wind direction and humidity were significant meteorological factors affecting PM10 concentration in Quanzhou.The results provided reference for further study of air pollution in Fujian triangle urban agglomeration.
