摘要(Abstract)：

为探索PM2.5的分布规律及其影响因素,对2013年西安市13个监测站点的全年ρ(PM2.5)数据进行了统计与整理。分析了ρ(PM2.5)的时空分布,采用聚类分析、小波变换研究了ρ(PM2.5)的区域分布特征与年际变化及突变特征,并对相关因素进行了探讨。结果表明,西安市ρ(PM2.5)在时间分布上具有冬高夏低的特点,而在空间分布上则以市人民体育场和草滩监测点所在区域为ρ(PM2.5)高值中心;ρ(PM2.5)在空间上可分为3大类,纺织城监测点单独为1类,经开区与草滩监测点为2类,另外10个监测点为3类,聚类效果的相关系数为0.7994,显示聚类效果较好;在ρ(PM2.5)年际变化中,除了6月和7月以外,其他月份ρ(PM2.5)均值为147.29μg/m3,日照时间短和静风是导致ρ(PM2.5)发生突变的主要气象因素。
