Uncovering the Impact of Urban Functional Zones on Air Quality in China
Abstract. This study presents a comprehensive spatiotemporal analysis of air quality across various urban functional zones in China from 2017 to 2022, uncovering distinct impacts on air quality due to the unique characteristics of each zone. A general decrease in various pollutant concentrations is observed, a result of stringent pollution control policies. Residential, commercial, and industrial zones show significant declines, whereas the transportation zone experiences the least decrease. However, ozone levels rebound significantly in densely populated residential and commercial zones, and exhibit distinct weekend effects. The research highlights U-shaped seasonal patterns for five key pollutants and inverse seasonal patterns for ozone, which gradually decrease. Furthermore, the daily and seasonal variations of pollutant concentrations in industrial zone are the largest, while those in the public management and service zone are the smallest. Notably, spatial heterogeneity is evident, with regional pollutant distributions linked to local emissions, control measures, urban morphology, and climate variability. These findings indicate that, in the future, the Chinese government should curb ozone pollution, strengthen air pollution control in transportation zone, and formulate more scientific and accurate air pollution control policies based on the local situation of each city. This study emphasizes the critical link between urbanization and air quality, advocating for continuous monitoring and the development of zone-specific air quality strategies to ensure sustainable urban environments.

In this study, the concentration of air pollutants in different urban functional areas was counted by means of cartographic classification criteria. This novel idea is of great significance to the study of urban air pollution. In the future, the author can consider carrying out specific case studies for typical cities and expanding management experience.

This comprehensive spatiotemporal analysis of air quality across various urban functional zones in China is very meaningful. However, I feel like the authors are off topic. The authors' subsequent analysis did not focus on the data analysis of the division of different urban functional zones, especially the final conclusion did not emphasize the effects of which urban functional zones in which types of cities.
The main problems are as follows.
- The annotation of references is not standardized, for example, “Zhang et al., 2022c” on line 26 should be “Zhang et al., 2022a”.
- This translation of “the Three-Year Action Plan for Winning the Blue Sky Defense Battle” on line 117 and “Suzhou and Qingdao have the most residential zone sites,” on line 186, etc. is inappropriate, which is too Chinglish.
- What is the meaning of this paragraph on line 117-121 in “2.1 Study area”? Why is it placed here?
- The production of Figure 1 is not standardized. Because the latitude and longitude grid has already been marked in Figure 1, there is no need for a compass.
- “2.3.1 Data preprocessing” should be placed in “2.2 Data sources”.
- I haven't found any specific data analysis or research methods in “2.3 Data analysis methods”.
- “3.4 Analysis of influencing factors” only includes three single factor analyses, which is too simple.
- Overall, this manuscript contains too much data description and lacks data analysis, especially discussion.
- When analyzing the impact of different urban functional zones on air quality, the authors overlooked the scale effect of different functional zones, especially the scale effect of various level cities.
- “These findings indicate that, in the future, the Chinese government should curb ozone pollution, strengthen air pollution control in transportation zone, and formulate more scientific and accurate air pollution control policies based on the local situation of each city.” on line 18-21 is not the focus in “Abstract”, which doesn't need to be placed here.
