摘　　要：根据2018年~2022年济南市和青岛市的污染监测数据,对比分析两市PM_(2.5)和O_(3)的污染特征及其相互作用规律。结果表明,济南市PM2s的年均质量浓度较青岛市偏高20μg/m^(²),两市O_(3)的年均浓度相近,但夏季青岛市O_(3)的质量浓度峰值低于济南市37μg/m。两城市PM_(2.5)和O_(3)相互作用关系存在明显差异,PM_(2.5)与O_(3)在冷季时均呈负相关性,在暖季时均呈正相关性。暖季时青岛市PM_(2.5)与O_(3)的正相关性均较济南市更高。青岛市PM_(2.5)和O_(3)的浓度分布均较济南市更加集中。This study used pollution monitoring data during 2018~2022 to compare and analyze the pollution characteristics and interaction patterns of PM_(2.5) and O_(3)in Ji'nan and Qingdao.The results show that the annual average PM_(2.5) concentration in Jinan is higher than that in Qingdao about 20μg/m^(3).The annual average concentrations of O_(3)are similar,but the peak concentration of O_(3) in Qingdao during summer is 37μg/m^(3)lower than that in Ji'nan.A significant difference appears in the interaction relationship between PM_(2.5) and O_(3)of the two cities.There is a negative correlation between PM_(2.5) and O_(3)changes during cold seasons and a positive correlation during the warm seasons.The positive correlation between PM_(2.5) and O_(3)in Qingdao during the warm season is higher than that in Ji'nan.The concentration distribution of PM_(2.5) and O_(3)in Qingdao is more concentrated than that in Ji'nan.
