摘要: 对2013-2015年重庆主城区空气重污染情况进行统计，并结合地面和高空探测手段，分析了一次典型重污染过程的污染特征。结果表明：重庆主城区秋冬季节的空气污染，以受不利气象条件影响的本地细颗粒物（PM2.5）累积污染为主，PM2.5占PM10的平均比例为72%左右；大气能见度与颗粒物浓度、相对湿度均呈现明显的负相关性。典型污染期间的近地层颗粒物污染带主要在0~400 m的高度范围，AOD值高达2.0~2.4，α指数在1.0左右。二次粒子、机动车尾气、扬尘是污染期间重庆主城区PM2.5的主要来源。

Abstract: Heavy air pollution events from 2013 to 2015 in Chongqing urban area were summarized, and pollution characteristics of a typical heavy pollution process were analyzed by means of ground and high altitude detection tools. Results showed that pollution events occurred in autumn and winter were mainly caused by unfavorable meteorological situation, under which local fine particulate matter was easy to accumulate. During pollution period, PM2.5 accounted for around 72% of PM10. Atmospheric visibility showed a significant negative correlation with particle concentration and relative humidity. Particulate matter usually accumulated at the height ranging from 0 to 400 meters during typical pollution period, and AOD value was from 2.0 to 2.4, with αindex being 1.0. Source apportionment results indicated that secondary particles, vehicle exhaust and dust were major pollution sources.
