An analysis and investigation of the factors affecting the air quality index in various cities in China

Abstract

With the rapid progress of society, air pollution has gradually become the focus of people's concern, the impact of air pollution is very many factors, including but not limited to natural factors, human factors, geographic factors, etc., this paper is mainly from the natural factors and human factors, to explore its impact on air quality in the past five years, this paper first from the data itself, summarizes the distribution characteristics of the air quality in different regions of China, and then from the temperature and humidity throughout the year, to quantify its impact, and then with the help of time-series methods, to explore the air pollution indicators in the case of de-seasonalization of the air pollution indicators. This paper firstly summarizes the distribution characteristics of air quality in different regions of China from the data itself, then quantifies the impact of temperature and humidity throughout the year, and then explores whether the air pollution indicators satisfy the smooth distribution under the situation of de-seasonalization with the help of time series correlation method. The paper then compares the effects of several anthropogenic factors on the air through the gray correlation method. Finally, the influence of each factor in different parts of the country is summarized to provide reference for future studies.
