哈尔滨市AQI与空气污染物的相关分析研究

空气质量问题已成为民众关注的热点问题.选取哈尔滨市2014年-2015年AQI日报数据,分别分析了供暖期和非供暖期PM2.5、PM10、CO、SO2、NO2、O3六种主要空气污染物与AQI的相关性,结果表明,AQI与6个主要污染物间呈显著性相关.同时建立了供暖期和非供暖期AQI与主要空气污染物的多元线性回归模型,结果表明,CO对AQI起着主要作用.因此,提高供暖过程中煤炭燃烧效率,可有效削减空气中CO的浓度,对于改善空气质量起着至关重要的作用.

Correlation Analysis between AQI and Air Pollutants in Harbin City

Air quality issue has been a hot topic for the government and the people.By selecting AQI data in 2014~2015 in Harbin, the author studies of main air pollutants on AQI the major air pollutants which include PM2.5, PM10, CO, SO2, NO2 ,O3.The results show that six major air pollutants have correlation with AQI.Established heating period and no heating period of multiple linear regression model between AQI and main air pollutants.The results showed that CO plays a major role on AQI.In the analysis of PM2.5, the result showed that CO plays an important role on PM2.5.As a result, increasing combustion ration of coal in Harbin coal can reduce the concentration of CO in air can decrease the value of AQI, which plays a crucial role on improving air quality.
