【摘要】：本文使用中国环境保护局提供的网络实时空气质量数据,采用断点回归分析方法,考察了南京地铁3号线的开通对南京市空气污染指数(AQI)和各类空气污染物(PM2.5,PM10,CO,NO2,O3,SO2)的影响。研究结果显示,在控制了相关天气与当地工业排放等因素的前提下,南京地铁3号线的开通依然显著降低了南京市污染指数以及部分空气污染物(PM2.5,PM10,O3)的污染水平,然而对CO,NO2,SO2等污染物的减排效果并不显著,说明了在一定程度上3号线的开通对南京市空气质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.
