【摘要】：本文使用中國環(huán)境保護局提供的網(wǎng)絡(luò)實時空氣質(zhì)量數(shù)據(jù),采用斷點回歸分析方法,考察了南京地鐵3號線的開通對南京市空氣污染指數(shù)(AQI)和各類空氣污染物(PM2.5,PM10,CO,NO2,O3,SO2)的影響。研究結(jié)果顯示,在控制了相關(guān)天氣與當(dāng)?shù)毓I(yè)排放等因素的前提下,南京地鐵3號線的開通依然顯著降低了南京市污染指數(shù)以及部分空氣污染物(PM2.5,PM10,O3)的污染水平,然而對CO,NO2,SO2等污染物的減排效果并不顯著,說明了在一定程度上3號線的開通對南京市空氣質(zhì)量具有污染治理效果。
[Abstract]:In this paper, the real time air quality data provided by China Environmental Protection Agency and breakpoint regression analysis are used. The effects of the opening of Nanjing Metro Line 3 on the air pollution index (AQI) and various kinds of air pollutants (PM2.5 / PM10 / CON2NO2O3SO2) in Nanjing were investigated. The results showed that the relevant weather and local industrial emissions were controlled. The opening of Nanjing Metro Line 3 still significantly reduced the pollution index of Nanjing City and the pollution level of some air pollutants, PM2.5 and PM10O3. However, the emission reduction effect on pollutants such as CONO _ 2O _ 2 and so _ 2 was not significant. It shows that the opening of Line 3 has pollution control effect on air quality in Nanjing to some extent.
