Abstract:At present,urban air quality is becoming a critical factor affecting people’s lives,which is also a focal point people concern about.with the accelerating process of urbanization and industrialization and the growing consumption of energy,there exists an outstanding problem of urban air pollution.The current situation of haze weather is a case in point,which triggers serious effects on people’s lives,production and health.Hence it is imperative for humans to concentrate on the evaluation of urban air quality and relevant researches.This article choose PM10,SO2,NO2,figure out urban primary and secondary air pollutants of Nanjing from 2006 to 2015 by caculating air pollutant load factor based on ambient air quality standards(GB30952012).Using Spearmans rank correlation coefficient,analyse the tendency of pollutant concentrations of the three pollutants in Nanjing from 2006 to 2015.Utilize gray correlation method to calculate the correlation between air quality and their impact factors including natural,social and economical factors.Also,still using gray correlation method,this article illustates the collelation between Nanjing’s air quality and that of the cities surrounding Nanjing based on the month average concentrations of SO2,NO2 ,PM2.5 and PM10 from Jan,2015 to Dec,2016.On the basic of research conclusions,this article summarizes practical actions to be taken to avoid air pollution.
