摘　　要：选取琅琊区政府和市图书馆两处监测点位,通过解析车对其周边环境进行短时间的组分监测,采用正交矩阵因子法(PMF)分析了解析车获取的数据。两个监测点位的PM2.5组份占比结果显示:二次无机盐为颗粒物的主要组分,两点位OC、EC组分占比的差别较大,市图书馆点位OC、EC占比均高于琅琊区政府;在本次监测时段中,琅琊区政府点位和市图书馆点位移动源和工业源占比相对较高。Two monitoring points,the Langya district government and municipal library,were selected for a short-time monition of the atmospheric components in the surrounding environment by analytical vehicles. The data obtained were analyzed using Positive Matrix Factorization( PMF). The proportion of PM2.5 in these two monitoring points showed that secondary inorganic salt was the main component of particulate matter. The proportions of OC and EC in the municipal library were quite higher than those of Langya district government. During this monitoring period,the proportions of mobile source and industrial source were relatively high at these two monitoring points.
