| 摘 要： | 根据龙华新区2个空气监测站2012年监测数据、气象数据以及不同污染源的排放数据,分析龙华新区空气质量现状,灰霾日数与PM2.5和PM10的相关性,并通过AERMOD模型着重探讨PM2.5和PM10的污染特征,计算不同污染源对PM2.5和PM10浓度的贡献率。结果表明,灰霾日数和PM2.5、PM10浓度均表现为明显的季节性变化,变化趋势较为一致,且灰霾日数与PM2.5的相关性较PM10更显著。龙华新区PM2.5和PM10主要来自本地源,其中PM2.5的主要来源为机动车尾气和道路扬尘,而PM10的主要来源为施工项目和裸地。

| Abstract: | Based on data from air quality monitoring stations, meteorological stations and different pollution sources during 2012 in Longhua District, this paper analyzed the air quality in Longhua District and the correlation between haze and PM2.5/PM10, the charac- teristics of PM2.5/PM10 and calculates the contribution rate of different pollution on PM2.5/PM10 concentration by AERMOD model. The results showed that the number of haze days and PM2.5/PM10 concentrations showed the same seasonal changes, and the correlation between haze and PM2.5 is significant than the correlation between haze and PM10. PM2.5/PM10 mainly from local sources, while PM2.5 mainly from vehicle exhaust and road dust, and PM10 mainly from construction projects and bare land in Longhua. |
