2017~2020年高明区春节及元宵期间空气质量分析研究

Air Quality Analysis of Gaoming District during Spring Festival and Lantern Festival from 2017 to 2020

对2017~2020年春节及元宵期间,高明区内布设的环境空气质量自动监测站数据及气象条件进行分析,结果表明有利的气象条件可以有效改善空气质量,但并不是高明区空气质量每年改善的主要因素,企业停工停产、汽车尾汽减少才是主要因素。无论气象条件如何,集中燃放烟花爆竹都能对高明区环境空气质量造成短暂严重影响,导致空气中PM10、PM2.5等污染物浓度显著上升。

During the Spring Festival and Lantern Festival from 2017 to 2020,the data and meteorological conditions of automatic monitoring stations for ambient air quality in Gaoming District were analyzed.The results show that favorable meteorological conditions can effectively improve air quality,but they are not the main factors for the annual improvement of air quality in Gaoming District.The main factors are the shutdown of enterprises and the reduction of automobile exhaust.No matter what the meteorological conditions are,the concentration of fireworks and firecrackers can cause a short-term serious impact on the ambient air quality in Gaoming District,resulting in a significant increase in the concentration of PM10,PM2.5 and other pollutants in the air.
