Analyzing Characteristics And Impacting Factors Of The Urban Air Pollution In Gao Ping In The Twelfth Five-Year Based On Air Quality Data

In recent years,the city's air pollution has caused to people's normal social life,especially haze invasion,therefore,Air pollution has become the most urgent task in today's society.However,in order to solve this problem,it is necessary to fully understand the local air pollution situation and causes all aspects of air pollution.There are studies that the factors that affect the poor quality of urban air in addition to economic growth caused by increased energy consumption,environmental protection measures should not be timely,there are different regions of their unique terrain and weather conditions and other reasons.Based on this problem,this paper analyzes the atmospheric environmental monitoring data and meteorological data in Gao ping during the "12th Five-Year Plan" period,and analyzes the pollution characteristics of the target air pollutants at different time scales.On this basis,Air quality is to be assessed,and air pollution reasons are to be explored.In this study,the main findings are:(1)The SO2 daily change is obvious like the “U” type.The pollutants performed obvious seasonal trend.Except for NO2 and O3.On the whole,the concentration of particulate matter is the highest in each season,the pollution situation is more serious.(2)The monthly variation of AQI value was stable and statistically significant in Gao ping.The AQI value in winter was the highest in all seasons.The AQI value of the heating period was also higher than the AQI value of the non-heating period,and seasonal variation don't have statistical significance.The categories and proportions of the primary pollutants have obvious seasonal differences in Gao ping.(3)By analyzing the relationship between air quality and meteorological parameters in the same period,it is found that the local air pressure and humidity are proportional to AQI,that is,the greater the pressure and humidity values,the more likely to cause heavy pollution of the weather;the temperature,precipitation and wind speed Ease air pollution,inversely proportional to the AQI value.(4)The scatter diagram of PM10 and PM2.5 concentrations showed a significant positive relationship in different seasons.The concentrations of SO2 and CO showed a significant positive correlation in winter,spring and autumn.There was a significant linear positive correlation among NO2,SO2,CO.There was no significant correlation between the gaseous pollutants in summer.There was a significant linear correlation between PM2.5 and CO concentration in winter,spring and autumn.There was a significant linear correlation between PM2.5 and SO2 in spring and PM2.5 and SO2 in autumn were extremely linearly positively correlated.The relationship between PM2.5 and O3 was very significant in summer and autumn,and there was a significant linear correlation between PM2.5 and CO.
