Urban Green Infrastructure (UGI) plays a crucial role in enhancing ecological resilience and ensuring spatial equity in contemporary urban planning. In post-socialist cities such as Zhytomyr, ongoing densification processes intensify pressure on existing green systems and contribute to structural imbalances between built-up areas and the availability of ecosystem services. GIS-based approaches provide an effective analytical framework for identifying these disparities and supporting evidence-based decision-making.
This study examines the spatial relationship between building density, green space distribution, and accessibility within the urban fabric of Zhytomyr. Open-source geospatial data from OpenStreetMap were used to construct a detailed block-level model of the city. All datasets were harmonized within a metric projection to enable accurate area calculations. Using QGIS, a set of spatial indicators - density, density index, Green Index, and 500-m network-based accessibility zones - was calculated through spatial joins, zonal statistics, and network analysis.
The results reveal significant territorial asymmetry in the interaction between development intensity and green infrastructure. The historic core and large multi-storey residential districts exhibit the highest density values while simultaneously demonstrating the lowest green balance, indicating limited ecological compensation capacity. In contrast, quarters adjacent to the river valley and peripheral forested areas show substantially higher ecological stability. The accessibility model further indicates that many high-density and densely populated districts do not meet normative walking access standards to public green spaces, highlighting a spatial disparity between the demand for and supply of UGI.
The developed indicators provide an evidence-based foundation for municipal planning and can support strategic interventions aimed at strengthening Zhytomyr’s green infrastructure network.
