| Abstract:To explore the main reason of air pollution, we analyzed the correlation between monitoring index of air pollution PM2.5 and other monitoring indexes of AQI, and found that PM2.5 was associated positively with SO2, NO2, CO, and negatively with O3 and the temperature. Then we got the numerical relationship between PM2.5 and the main factor according to multiple regression model. The results offers some references to the control of PM2.5 in Xi'an. |
