Abstract
Green infrastructure and ecosystem services have emerged as critical concepts for enhancing environmental planning in urban areas, as they provide a more comprehensive understanding of the complex and dynamic relationships within socio-ecological systems. This study aims to conduct a meta-analysis on the role of green infrastructure in sustaining urban ecosystem services in Tehran metropolis. The research adopts an applied, descriptive–analytical approach, combining systematic literature review and path analysis. The systematic review was conducted using bibliometric analysis of articles published between 1995 and 2024, with the support of VOSviewer software. For the path analysis, the SMARTPLS software was employed. The statistical population consists of experts in the field of green infrastructure and urban ecosystem services, from whom a purposive sample of 96 individuals was selected using Cochran’s formula. The findings from the systematic review revealed a significant increase in scientific attention to green infrastructure, ecosystem services, and urban issues since 2005. Co-authorship analysis highlighted the scientific leadership of the USA, Germany, and the UK, while keywords such as “ecosystem services” and “green infrastructure” were central to academic discourse. Structural equation modeling indicated that all pathways from green infrastructure to urban ecosystem services were statistically significant at the 95% confidence level. The significance values for spatial networking (5.170), multifunctionality (2.183), strategic planning (3.177), ecological quality (2.546), and human well-being linkage (2.555), as well as the overall impact of green infrastructure (5.441), confirm the positive and meaningful influence of green infrastructure on ecosystem service sustainability. These findings underline the necessity for policymakers to prioritize the strategic development and enhancement of green infrastructure as a foundational step toward more sustainable urban futures.
