摘　　要：针对日益严重的城市大气污染问题,提出遥感监测下的城市主要大气污染物环流聚类时空分布特征分析方法。确认区域监测点数量,形成监测网,分析各个区域城市主要大气污染物的关联性与相似性,联合污染物对应的因子荷载与遥感监测数据属性信息,对主要大气污染物展开环流聚类分析,获得大气污染物的时间分布特征和空间分布特征。实验结果表明,以山东省为例,其大气污染最为严重区域为鲁西地区,空气质量最高区域为胶东半岛;山东省大气污染物在夏季的浓度值相对较低,在冬季的浓度值最高。In response to the increasingly serious problem of urban air pollution,a method for analyzing the spatiotemporal distribution characteristics of the main atmospheric pollutants circulation clustering in cities under remote sensing monitoring is proposed.This study confirmed the number of regional monitoring points to form a monitoring network in order to analyze the correlation and similarity of major atmospheric pollutants in various regional cities.By combining the factor loads corresponding to pollutants with remote sensing monitoring data attribute information,it conducts circulation clustering analysis on major atmospheric pollutants,and obtain the temporal and spatial distribution characteristics of atmospheric pollutants.Taking Shandong Province as an example,the area with the most severe air pollution is the western Shandong region,and the area with the highest air quality is the Jiaodong Peninsula.The concentration values of atmospheric pollutants in Shandong Province are relatively low in summer and the highest in winter.
