| 摘 要： | 为了解重庆市北碚区大气质量状况,利用其2014年气溶胶光学厚度和颗粒物质量浓度的同步观测结果进行分析.结果表明,北碚区AOD_(500 nm)的年均值为1.46±0.69,其随月份变化明显,其中11月最高为2.90±1.85, 9月最低为0.54±0.05.北碚区存在颗粒物污染的现象,PM_(2.5)和PM_(10)的年均值分别为(62±40)μg·m~(-3)和(94±51)μg·m~(-3),均超出GB 3095-2012《环境空气质量标准》二级标准限值,PM_(2.5)与PM_(10)的日均值超标率分别为26%和15%.细粒子PM_(2.5)与可吸入颗粒物PM_(10)浓度之间呈现显著性相关,全年决定系数R~2能够达到0.95(P0.01),AOD与PM_(2.5)、 PM_(10)之间全年均呈正相关特性,全年决定系数R~2分别为0.48和0.46,且不同季节下的决定系数和相关函数均有差异,其中冬季相关性最好,夏季相关性最差.全年AOD与AQI呈正相关特性,决定系数R~2为0.15(P0.05).AOD值受天气要素综合作用的影响,观测期间也应将温度、湿度、水汽等要素数据进行同步采集.
