统计分析了深圳市罗湖区2019年主要空气污染物的浓度,探究了罗湖区常规大气污染物浓度的变化趋势,及其与气象因素间的相关性,对2019年罗湖区2次污染事件进行了潜在源分析,并对臭氧(O3)进行了主成分分析.结果表明,2019年罗湖区各大气污染物浓度受季节影响较大,且出现"周末效应",全年348 d有效数据中,主要污染物为O3的天数为225 d,占比64.66%,2019年罗湖区的主要污染物为03.罗湖区颗粒物浓度与其他污染物之间相关性较为显著,大气环境中各污染物浓度与气温、风力和相对湿度呈较显著相关.2次大气污染事件的潜在源分析结果表明,东北方向(如东莞市等)为罗湖区O3和PM2.5的潜在输入源.通过对O3浓度的主成分分析解析出了 4个主成分,影响罗湖区大气O3浓度的主要因素为风力、湿度、PM2.5、PM10和SO2.研究结果为罗湖区大气污染污染控制与治理提供了参考.
ANALYSIS OF VARIATION CHARACTERISTICS OF AIR QUALITY IN LUOHU DISTRICT OF SHENZHEN IN 2019
In this study,the concentrations of major air pollutants in Luohu District of Shenzhen in 2019 were statistically analyzed,the trend of conventional air pollutant concentration in Luohu District was explored,and the correlation between atmospheric pollutant concentration and meteorological factors in Luohu District was analyzed.The potential source analysis of two pollution events in Luohu District in 2019 was analyzed,the principal component analysis of the main pollutant ozone in Luohu District was carried out,and finally,air pollution control suggestions and countermeasures were put forward for Luohu District.The results showed that the concentration of air pollutants in Luohu District in 2019 was greatly affected by the season,and there was a weekend effect,among the 348 effective data of the year.The number of days with the main pollutant as ozone was 225,accounting for 64.66%of the whole year,and the main pollutant in Luohu District in 2019 was ozone.The correlation between particulate matter concentration and other pollutants in Luohu District was significant,and the concentration of pollutants in the atmospheric environment was significantly correlated with temperature,wind,and relative humidity.The results of the analysis of the potential sources of the two air pollution events showed that the northeast direction including Dongguan etc.,was the potential input source of O3 and PM2.5 in Luohu District.Four principal components were analyzed through the analysis of the principal component of ozone concentration,of which the first component could explain 59.2%of the ozone concentration,and the main factors affecting atmospheric ozone concentration in Luohu District were wind,humidity,PM2.5,PM10 and SO2.This study provides a reference for the control and treatment of air pollution in Luohu District.
