摘要

选取河北省唐山市2017年12月27~31日一次典型重污染过程，开展其污染特征及成因分析，对污染期间气象要素、大气颗粒物组分特征进行综合研究.结果表明，此次大气重污染过程中PM_2.5平均质量浓度为154μg/m³，重度污染及以上时PM_2.5/PM₁₀为0.7；PM_2.5中SNA质量浓度占比达58.0%，OC/EC的比值为4.1，说明颗粒物二次反应和有机物在此次污染过程有较大贡献；长期均压场以及近地面高湿、小风、逆温的出现导致唐山地区大气层结稳定，加之周边地区区域传输的贡献，是导致此次大气重污染过程的重要影响因素.

Abstract：

Characteristics and formation mechanism of a heavy air pollution event during the period from December 27^th to 31^st, 2017 in Tangshan, Hebei, China were investigated. Combined with the mass concentration of particulate matter, gaseous pollutant concentrations, carbonaceous species and meteorological data, the component analysis of PM_2.5 was conducted in detail for this episode. The results showed that the average mass concentration of PM_2.5 during this period was 154μg/m³ exceeding the secondary standard of daily average concentration of the ambient air quality standard (GB3095-2012). When the air pollution level was 5 and above, passed the level of heavy and above, the ratio of PM_2.5 over PM₁₀ became 0.7. The mass concentration of SNA accounted for 58.0% of PM_2.5, and the value of OC/EC was 4.1, which indicated that the secondary reaction of particulate matter and organic matter had a greater contribution in this pollution process. The local meteorological conditions, continuous uniform pressure field, the near-surface high humidity, light breeze and temperature inversion all played an important role in this heavy pollution event. Regional transmission was also an important contribsuting factor to this heavy pollution process.
