【摘要】：2013年9月10日國務(wù)院頒布了《大氣污染防治行動(dòng)計(jì)劃》(下稱《行動(dòng)計(jì)劃》).為研究《行動(dòng)計(jì)劃》頒布前后我國不同地區(qū)大氣污染狀況變化及其防治措施效果,通過分析2013—2014年“中國大氣氣溶膠研究網(wǎng)絡(luò)(CARE-China)”36個(gè)監(jiān)測(cè)站點(diǎn)ρ(PM2.5),結(jié)合同期環(huán)境保護(hù)部公布的74個(gè)重點(diǎn)城市大氣主要污染物濃度數(shù)據(jù)和OMI衛(wèi)星數(shù)據(jù),分析了我國不同地區(qū)ρ(PM2.5)變化及其原因;同時(shí),以北京為例,分析了不同粒徑段中顆粒物質(zhì)量濃度變化的原因.結(jié)果表明:1京津冀及其周邊、長三角、珠三角、西南、成渝、西北、華中、關(guān)中和東北9個(gè)地區(qū)ρ(PM2.5)年均值下降了1.1~16.3μg湓m3.其中,京津冀及其周邊、長三角、珠三角、成渝和關(guān)中地區(qū)降幅均超過10.0%,分別為10.2%、10.7%、11.6%、16.9%和20.8%.2不同地區(qū)ρ(NO2)和ρ(SO2)年均值變化基本一致,近地面ρ(NO2)年均值在京津冀及其周邊、珠三角、西南、成渝和華中等地區(qū)降幅在3.0%~9.2%之間,但是華北平原地區(qū)NO2柱濃度下降明顯,降幅在10.0%~20.0%之間.3北京地區(qū)ρ(PM1)和ρ(PM2.5)年均值分別下降了5.7和0.2μg湓m3,并且ρ(NO3-)和ρ(SO42-)年均值在PM1和PM2.5中均有所下降,但ρ(PM1~2.5)與其ρ(NH4+)年均值升幅分別為27.9%和16.2%.因此,京津冀及其周邊地區(qū)在防治措施實(shí)施過程中,在控制高架點(diǎn)源與實(shí)施脫硝措施等情況下,應(yīng)逐步加強(qiáng)近地面面源和線源的控制力度;在實(shí)施SO2和NOx減排措施的同時(shí),還需要重視機(jī)動(dòng)車三元催化過程和燃煤電廠脫硫脫硝過程中可能導(dǎo)致的NH3排放問題.
[Abstract]:In September 10th 2013, the State Council promulgated the Action Plan for the Prevention and Control of Air pollution (hereinafter referred to as the Action Plan). In order to study the changes of air pollution in different regions of China before and after the promulgation of the Action Plan and the effect of its control measures. Based on the analysis of 36 monitoring stations of CARE-China (2013-2014), there are 36 monitoring stations 蟻 (PM2.5) in China Atmospheric Aerosol Research Network (CARE-China). Based on the atmospheric pollutant concentration data of 74 key cities and OMI satellite data published by the Ministry of Environmental Protection in the same period, the variation of 蟻 (PM2.5) in different regions of China and its causes are analyzed. At the same time, taking Beijing as an example, the reasons for the change of mass concentration of particulate matter in different particle size segments were analyzed. The results showed that: 1 Beijing-Tianjin-Hebei and its periphery, Yangtze River Delta, Pearl River Delta, Southwest, Chengdu-Chongqing, Northwest, Central China. The annual mean value of 蟻 (PM2.5) in Guanzhong and nine regions in northeast China has decreased by 1.11 / 16.3 渭 g / m ~ (3). Among them, the Beijing-Tianjin-Hebei region and its periphery, the Yangtze River Delta and the Pearl River Delta. The decreases in Chengdu-Chongqing and Guanzhong areas were more than 10.0%, 10.7% and 11.6%, respectively. The annual mean values of 蟻 _ (no _ 2) and 蟻 _ (so _ 2) in different regions of 16.9% and 20.8.2 are basically the same. The annual mean values of 蟻 _ (no _ (2)) near the surface are in and around Beijing, Tianjin and Hebei, the Pearl River Delta, and the southwest of China. In Chengdu-Chongqing and Central China, the decrease was between 3.0% and 9.2%, but the concentration of NO2 column in North China Plain decreased obviously. The annual mean values of 蟻 (PM1) and 蟻 (PM2.5) in Beijing decreased by 5.7 and 0.2 渭 g / m ~ 3 respectively between 10.0% and 20.0%. And the annual mean values of 蟻 _ (no _ (3)) and 蟻 _ (so _ 4 _ (2)) decreased in both PM1 and PM2.5. But the annual mean increases of 蟻 (PM1) 2.5) and 蟻 (NH _ 4) are 27.9% and 16.2respectively. Therefore, the prevention and control measures in Beijing-Tianjin-Hebei and its surrounding areas are in the process of implementation. Under the condition of controlling elevated point source and implementing denitrification measures, the control of near ground surface point source and line source should be strengthened step by step. While implementing SO2 and NOx emission reduction measures, it is necessary to pay attention to the problem of NH3 emissions caused by the ternary catalytic process of motor vehicles and the process of desulfurization and denitrification in coal-fired power plants.
