Abstract
The rapid urbanization in China in the last decade has brought about severe air pollution problems. To provide a theoretical basis for improving the air environment, this paper analyses air quality’s spatial and temporal evolution in 13 prefecture-level cities in Hubei Province. It analyses the influence of various urbanization indicators on the AQI. Based on the existing literature, this paper selects six indicators to measure the level of urbanization of each city in three dimensions: population, economy and urbanization of land, and then uses the AQI of 13 prefecture-level cities in Hubei Province from 2015 to 2017 as the basis to analyze the annual and monthly changes of AQI values in each city in Hubei Province over three years and uses ArcGIS to make AQI values spatial distribution map. The urbanization index was then regressed on the AQI values to study the impact of urbanization level on the spatial and temporal evolution of air quality in each prefecture-level city in Hubei Province.
Highlights
Since the reform and opening-up, China has entered a period of rapid urbanization, with the urbanization rate rising from 17.92% in 1978 to 60.60% in 2019.(Qiu & Huang, 2020)
This paper examines the effects of various urbanization factors on air pollution (AQI values) using panel data for 13 cities in Hubei Province from 2015 to 2017
The three dimensions of urbanization in terms of population, economy, and land are used to measure the level of urbanization in each city
Summary
Since the reform and opening-up, China has entered a period of rapid urbanization, with the urbanization rate rising from 17.92% in 1978 to 60.60% in 2019. (Qiu & Huang, 2020). This development in urbanization has several benefits, such as increased infrastructure and social services, making people’s lives more convenient and comfortable. In terms of industrial progress and technological innovation, urbanization has created lots of wealth. Growing urbanization has serious environmental consequences in many cities. Yang pound air pollution problems such as haze, photochemistry and air pollution smog are becoming increasingly prominent (Chan & Yao, 2008). People’s health is adversely damaged by severe air pollution conditions like haze. The factors impacting air quality must be studied in detail in terms of spatial and temporal evolution
