摘要
根据2016~2020年国家空气质量监测系统监测数据,分析了新昌县空气质量的变化,同时应用HYSPLIT后向轨迹聚类分析研究了典型月份代表性污染物传输情况。结果表明,O3污染传输主要来自宁波、舟山方向,其次为湖州、嘉兴和上海方向;PM2.5污染传输主要来自湖州、嘉兴,上海,宁波、舟山三个方向,其次为杭州等方向。针对新昌县的大气污染特征,本文提出了工业废气治理、移动源污染治理、区域低碳减排等相关大气污染防治措施。分析结果为华东地区山区县市大气污染防治研究提供了参考。
According to the monitoring data of the national air quality monitoring system from 2016 to 2020, the changes of air quality in Xinchang County were analyzed, and the HYSPLIT backward trajectory clustering analysis was used to study the pollution transmission in typical months. The results showed that,O3 and PM2.5 in Xinchang County are affected by imported pollution and local pollution. In September, the transmission of O3 pollution mainly came from Ningbo and Zhoushan, followed by Huzhou, Jiaxing and Shanghai;In December, the transmission of PM2.5 pollution mainly came from three directions of Huzhou, Jiaxing, Shanghai,Ningbo and Zhoushan, followed by Hangzhou and other directions. In view of the air pollution characteristics of Xinchang County,this paper also puts forward relevant air pollution prevention and control measures such as industrial waste gas treatment, mobile source pollution control, and regional low-carbon emission reduction. The analysis results provide a reference for the research on air pollution prevention and control in mountainous counties and cities in East China.
