北京地区气溶胶污染的本地源与区域输送源
首发时间:2012-06-20
摘要:通过对近年来不同污染来源对城市气溶胶物理、化学特性的研究进行总结和对比,并结合大气物理、大气化学原理,以北京市为例,分析了本地源以及区域输送两种途径的污染贡献率。其中,本地源的分析主要集中在交通、冬季供暖和春节期间燃放烟花污染等;区域输送来源途径主要是秸秆焚烧和沙尘传输。在研究气溶胶来源的基础上阐述了气溶胶理化特性的研究进展,为该学科后续发展提供一定帮助。

The local vs. transported aerosol sources over Beijing
Abstract:The aerosol physical, chemical and optical properties from different pollution sources were summarized and compared according to the former documents. The major contributions to the pollutants come from local and regional transport sources in Beijing were analyzed combined the former documents with the knowledge of the atmospheric physics and atmospheric chemistry. The local sources are focused on traffic, domestic heating in winter and firework pollution during Chinese New Year. The regional transportation sources are mainly from dust storm and biomass burning. The research progress on aerosol physical and chemical properties was reviewed on the basis of aerosol sources, and it is helpful for further research in this area.
Keywords: atmospheric environment atmospheric aerosol local sources transported sources
