摘要

为定量揭示城区和郊区O_3前体物对O_3生成的差异化影响，文章基于多重分形去趋势互相关分析法和K均值聚类算法，对2016-2022年四川省15个重点城市城区和郊区不同站点NO_2-O_3互相关性的多尺度特征进行对比分析。结果表明，城区和郊区大气NO_2-O_3互相关性均具有多重分形性及长期持续性特征，且郊区站点多重分形强度显著高于城区。城区和郊区NO_2-O_3互相关性多重分形强度差异呈现逐年递增规律，且受季节影响较大，其中夏季城区和郊区差异最大，冬季最小，这些差异主要受O_3前体物排放特征和热岛效应的影响。研究结果有助于从新的角度理解城区郊区大气污染差异及形成机理，为城郊O_3精细化预测模型的完善提供动力参数。
