Analysis of Factors Influencing Air Quality in Lanzhou City under Traffic Restriction Policy
摘要
Abstract
Motor vehicle exhaust emissions are one of the main sources of air pollutants.In order to understand the influencing factors of air quality in Lanzhou city under the policy of motor vehicle restrictions,this paper first conducts statistical analysis on the air quality data of Lanzhou city from 2016 to 2019,and then uses stepwise regression analysis to establish a multiple linear regression model between the Air Quality Index(AQI)and air pollutant concentration,and finally conducts correlation analysis between meteorological factors and air pollutant concentration.The results indicate that the restriction policy helps to improve air quality,and there is a significant correlation between AQI and air pollutant concentrations,as well as a significant correlation between meteorological factors and air pollutant concentrations.关键词
