Urbanization has led to severe environmental challenges, including air pollution, loss of biodiversity, and disruption of ecosystem services. Urban green infrastructure (UGI), encompassing parks, green roofs, street trees, and urban forests, plays a critical role in mitigating air pollution, regulating microclimate, and enhancing overall urban ecosystem services. This paper explores the mechanisms by which UGI contributes to air quality improvement, carbon sequestration, thermal regulation, and biodiversity conservation. The study synthesizes recent research, highlighting the integration of ecological, technological, and planning strategies to optimize UGI benefits. Furthermore, challenges such as limited space, maintenance costs, and social engagement are discussed. Innovative solutions, including multifunctional green spaces, vertical greenery, and smart monitoring systems, are presented. The findings underscore the importance of incorporating UGI into urban planning to achieve sustainable, resilient, and healthy cities.
