摘要
从本地生成和区域传输两方面对2017年大连市星海三站点位O_(3)污染原因进行了分析。结果表明,受持续性机动车尾气排放影响,本地光化学反应生成是星海三站点位O_(3)浓度在大连市10个国控点位中处于较高水平的原因之一;星海三站点位O_(3)生成对VOCs浓度敏感,且减少NO_(X)将有利于O_(3)的生成;星海三站点位O_(3)污染受到京津冀南部及山东中西部污染输送影响较大,且这种区域污染输送需要在一定的风速基础上才能够实现。
The causes of O_(3)pollution at Xinghaisanzhan site in Dalian in 2017 were analyzed from two aspects of local generation and regional transmission.It is concluded that,the formation of local photochemical reaction is one of the reasons why O_(3)concentration at Xinghaisanzhan site is at a high level among the 10 national control sites,which is mainly affected by persistent motor vehicle exhaust emissions.The generation of O_(3)at Xinghaisanzhan site is sensitive to VOCs,and reducing NOX will be beneficial to the generation of O_(3).The O_(3)pollution at Xinghaisanzhan site is greatly affected by the pollution transport in the south of Beijing-Tianjin-Hebei region and the Midwestern of Shandong,and such regional transportation can only be realized on the basis of a certain wind speed.
