【摘要】：在傳統(tǒng)的大氣監(jiān)測網(wǎng)絡(luò)子站污染物濃度比較的基礎(chǔ)上,結(jié)合其24h日變化的趨勢分析,對珠江三角洲9個(gè)城市59個(gè)監(jiān)測點(diǎn)位2013~2015年期間的CO、SO_2、NO_2、O_3、PM_(10)、PM_(2.5)數(shù)據(jù)進(jìn)行了分析,以期更深入地揭示珠江三角洲大氣污染的空間分布格局和來源特征.結(jié)果表明:CO、SO_2、NO_2、PM_(10)、PM_(2.5)主要污染區(qū)域集中在珠江三角洲西北部和中部地區(qū),主要以廣州和佛山兩個(gè)城市為污染中心,受到本地源排放貢獻(xiàn)較大;O_3污染分布較為復(fù)雜,四周污染濃度高,中部濃度低,但廣州和東莞兩地日變化差異顯著,受到本地源影響大.分析顯示,珠江三角洲大氣污染具有顯著的區(qū)域性特征,推薦廣州天湖和珠海唐家分別作為珠江三角洲北部和東南部的區(qū)域污染監(jiān)測點(diǎn),能夠較好地代表來自珠江三角洲北部的污染傳輸影響和珠江三角洲東南部的平均污染水平.
[Abstract]:On the basis of the comparison of the concentration of the pollutants in the traditional atmospheric monitoring network, combined with the trend analysis of 24h daily change, the data of CO, SO_2, NO_2, O_3, PM_ (10) and PM_ (2.5) of 59 monitoring points in 9 cities of the Pearl River Delta are analyzed in order to reveal the spatial distribution of air pollution in the Pearl River Delta. The results show that the main pollution areas of CO, SO_2, NO_2, PM_ (10) and PM_ (2.5) are concentrated in the northwest and central regions of the Pearl River Delta, mainly in two cities in Guangzhou and Foshan, which are mainly polluted by the local source, and the distribution of O_3 pollution is more complex, the concentration of the surrounding pollution is high, and the concentration in the central region is low, but Guangzhou and Dongguan The analysis shows that the atmospheric pollution in the Pearl River Delta has significant regional characteristics, and the Guangzhou Tian lake and the Zhuhai Tang family are recommended respectively as the regional pollution monitoring points in the northern and southeastern Pearl River Delta, which can better replace the pollution transmission effects from the Northern Pearl River Delta and the north of the Pearl River Delta. The average pollution level in the southeast of the Pearl River Delta.
