Study on Characteristics and Control Measures of Atmospheric Particle Pollution in the Main Urban Area of Luzhou City from March 2019 to February 2020

To study the characteristics and causes of particulate matter pollution in the main urban area of Luzhou City,the air automatic monitoring data from March 2019 to February 2020 were selected,and time variation characteristics,pollution source and correlation between PM2.5 and PM10 were analyzed by using Origin 2017 and other technical means.The results show that the variation trend of PM2.5 and PM10 has good consistency in different seasons,and the correlation characteristics of pollutants in different stations are obvious.The analysis shows that the particulate matter pollution in the main urban area of Luzhou city is mainly caused by industrial enterprise emissions,motor vehicle exhaust,biomass combustion,coal combustion,dust and adverse weather conditions,etc.It is suggested to control the six types of pollution emissions.
