Spatiotemporal Distribution of the Impact of Urban Development on Air Pollution

2025

Vol. 51, nr 1

21--35

This study applies China’s air pollution and urban development data from 2007 to 2021, and the temporally weighted regression (GTWR) model to analyze the spatiotemporal distribution characteristics of air pollution influencing factors. It was found that the temporal evolution of air pollution in different regions is highly consistent but its degree varies with the pollution severity. The impact of urban development on air pollution has significant spatiotemporal heterogeneity. Overall, urban green space area (UGSA), urban population density (UPD), and domestic waste removal volume (DWRV) have positive impacts, while urbanization rate (UR), per capita disposable income of urban residents (URI), and public vehicles per every 10 000 people (PTV) have negative impacts. The impact of USGA, UR, and URI is mainly visible in western provinces, the impact of UPD in northeast provinces, the impact of DWRV in eastern and central provinces, and the impact of PTV in eastern provinces.
