摘要

Urban green space (UGS) plays a critical role in mitigating air pollution and enhancing urban sustainability through ecosystem services. However, the complex interactions between UGS and air pollution present both benefits and challenges. By adopting an ecosystem services perspective, the study pursues two main objectives: on the ond hand, to conduct a comprehensive review of the interactions between UGS and air pollution; and on the other hand, to identify current limitations in the field and highlight future research trends. Our study examines this relationship through a comprehensive bibliometric analysis spanning from 2003 to 2025. Using data from the Web of Science, we analyze 422 relevant publications through co-occurrence analysis, keyword clustering analysis, and keyword burst detection, employing CiteSpace and VOSviewer for visualization. The results show that: (1) Our study identifies research hotspots, including the regulatory role of UGS in air pollution control, the impact of air pollution on green space quality, and the interactions between UGS, air quality, and public health. (2) Findings reveal three distinct research phases: initial focus on pollutant removal mechanisms, expansion into urban sustainability frameworks, and recent emphasis on climate adaptation and ecosystem resilience. (3) Future research should pay greater attention to the reciprocal interactions between UGS and air pollution. Our study provides valuable insights to guide future studies and supports the development of more effective strategies for integrating urban greenery into air quality management and sustainable urban planning.
