摘要：

为识别和量化深圳市大气PM2.5的污染来源,2014年3, 6, 9, 12月分别在5个站点采集PM2.5的膜样品并进行质量浓度及组分分析,利用正向矩阵因子解析（PMF）模型对其主要来源和时空变化规律进行了解析.结果表明,2014年深圳市PM2.5年均浓度为35.7μg/m3,其中机动车源、二次硫酸盐生成、二次有机物生成和二次硝酸盐生成是最主要的来源,质量浓度贡献比例分别为27%、21%、12%和10%;地面扬尘、生物质燃烧源、远洋船舶源、工业源、海洋源、建筑尘和燃煤源贡献比例达2%～6%.各个源贡献的时空变化特征表明,二次硫酸盐生成、生物质燃烧源、二次有机物生成、工业源、远洋船舶源和海洋源显示出明显的区域源特征,机动车源、二次硝酸盐生成、燃煤源、地面扬尘和建筑尘具有显著的本地源特征.
