چکیده

Green spaces are essential for sustaining both natural and human life in urban areas. Their absence can disrupt well-being, harm air quality, mental health, and biodiversity, and reduce overall quality of life. Maintaining and expanding these spaces is crucial for the resilience and sustainability of cities. The present study aims to analyze urban green space changes and per capita urban green space in Bojnurd, North Khorasan Province. This study examines Bojnurd’s per capita green space changes and the impact of the Urban Area Comprehensive Plan (UACP). To achieve these goals, green space areas were extracted using Landsat and Google Earth satellite images for the years 2006, 2013, and 2022. Furthermore, per capita urban green space was analyzed using demographic information and the area of green spaces at both the city level and within each of the two districts of Bojnurd municipality. The results indicate that per capita urban green space increased from 2006 (4.5 m²) to 2022 (5.59 m²), with both municipal districts showing growth, although Region One experienced a greater increase compared to Region Two. Implementing the UACP could further raise per capita green space to 9.81 m², thereby enhancing ecological balance and quality of life. A practical recommendation is to prioritize UACP implementation alongside the development of public green spaces. These findings provide a roadmap for urban planners to integrate green space development with demographic needs and urban policies. Prioritizing UACP execution and public green space expansion could contribute to creating more resilient and livable cities.
