Abstract
In recent years, various regions in China have been plagued by smog problems, and Zhengzhou, as the capital city of Henan, has a particularly prominent smog problem than other cities due to climate and economic development. In the past two years, smog pollution has improved slightly, but smog still plagues our lives. This paper analyses the changes in haze pollution in Zhengzhou in the past five years, draws the main reasons for the changes in haze pollution. Principal component analysis and regression analysis were used to establish a regression model of the influencing factors of haze in Zhengzhou. The results show that pollutant emissions and coal consumption have the most obvious impact on the degree of haze pollution in different years, and reasonable suggestions are put forward based on the current situation of haze pollution in Zhengzhou and the existing governance policies.
