Abstract

Expanding urban green space and creating a network of green spaces in the city, in addition to meeting citizens' needs for recreation and contact with nature by reducing air pollution, promoting biodiversity, enhancing diversity, and using existing agricultural and garden lands, lead to the formation of active urban ecosystems, and thereby expanded social relations, improved security and enhanced economic prosperity of gardens and agricultural lands. As a green infrastructure, it can influence the dynamism and sustainability of cities. In this research, the infrastructural components affecting the green network formation and ecosystem services provided by them were extracted from previous research by library study. Then, 25 urban green networks in the world, as case studies, were investigated to determine to what extent the abovementioned components were focused. The present study is descriptive-analytical correlational research. The samples were selected using a purposive sampling technique. The samples were evaluated and scored on a 5-point Likert scale. The results indicate that in the successful examples of expanding green infrastructure and forming urban green networks, there are basic components in the infrastructure and service sections that are necessary for the formation and expansion of the green network, as mentioned in the findings and conclusion sections. Moreover, considering the relationship between structure and service provision, the results show that the existence of infrastructure related to some ecosystem services does not necessarily lead to the provision of these services and influential lateral areas play an essential role in the efficient provision of ecosystem services.
