摘要
不同地区的大气污染水平往往由于污染源、气象条件的不同而有所差异,为探究广东省大气污染分布情况,根据 2022 年广东省 21 个城市 6 项大气污染物(PM2.5、PM10、NO2、O3、CO和SO2)的监测数据,分析其空间分布特征,探究影响因素.结果表明:按照《环境空气质量标准》(GB 3095-2012)及修改单评价,部分城市O3 年评价浓度超标,各地市其余指标年评价浓度均达二级标准.不同污染物在空间分布上多呈现集聚特征,从区域尺度来看,珠江三角洲中西部、粤北中西部地区污染相对较重,珠江三角洲中西部属于颗粒物、O3、NO2 浓度相对较高地区,粤北中西部地区属于颗粒物浓度相对较高地区.广东省大气污染水平和经济、气象因素密切相关,在探究的影响因素指标中,从广东省、珠三角地区来看,影响最大的因素为第二产业增加值,对于非珠三角地区,影响最大的因素为第三产业占GDP比重.
Abstract
The air pollution level in different regions varies with the pollution sources and meteorological conditions.To explore the air pollution distribution in Guangdong Province,based on the monitoring data of six air pollutants(PM2.5,PM10,NO2,O3,CO,and SO2)in 21 cities in Guangdong Province in 2022,the spatial distribution characteristics were analyzed to investigate the influencing factors.The results show that according to the Environmental Air Quality Standards(GB 3095-2012)and its revised form,the O3 annual concentration in some cities could be evaluated as Out of Limits,while the annual evaluation concentration of other indicators in other cities has reached the Second Level.The spatial distribution of different pollutants exhibited centralized characteristics.From a regional scale,the pollution in the central and western Pearl River Delta and the central and western regions of northern the Pearl River Delta is relatively heavy,meanwhile the central and western Pearl River Delta belongs to the regions with relatively high concentrations of particulate matter,O3 and NO2,and the central and western regions of northern Guangdong belong to the regions with relatively high concentrations of particulate matter.The level of air pollution in Guangdong Province is closely related to economic and meteorological factors.From the perspective of Guangdong Province and the Pearl River Delta,the most influential factor is the added value of the secondary industry;for regions out of Pearl River Delta,the most influential factor is the proportion of the tertiary industry to GDP.
