In the construction of resilient cities, regional air pollution prevention plays a pivotal role. Building on the previous research experience, the relationship between air pollution concentration and urban size exhibits a sublinear allometric growth pattern. To identify effective strategies for mitigating particulate matter air pollution, this study quantitatively explored 6 variables inffuencing urbanization in China’s cities and established an allometry model. Empirical analysis was conducted using data from 293 prefecturelevel cities and 1,827 county-level cities to examine the relationship between annual concentrations of ffne particulate matter PM2.5 and PM10 in the atmosphere. ① The ffndings of this study provided partial validation for the Kuznets curve and demonstrated a reverse ‘U’-shaped association between urbanization and levels of PM2.5 and PM10 pollution. ② By partitioning the Hu Huanyong line, this study identiffed the spatial distribution pattern of PM2.5 and PM10. In central and western regions, as urban size expands, inhalable particle concentrations tended to increase further; whereas in the southeast region, inhalable particle concentrations gradually decreased and stabilized after a certain threshold of urban scale expansion was reached. Among the factors inffuencing urban size, green coverage within built-up areas exerted the most signiffcant impact on both PM2.5 and PM10 concentrations, followed by the extent of built-up areas and the scale of secondary industries. This study presented an effective strategy for reconciling confficts between urban expansion and air pollution management, while concurrently promoting |
