This study developed a multidimensional spatial equity evaluation framework and found serious spatial inequity in the supply and demand of park green spaces in the main urban area of Harbin, with severe undersupply of mini-parks and overly concentrated distribution of comprehensive parks leading to polarized supply levels. Certain social groups, such as older people, rural dwellers, and low-income individuals, are disadvantaged in accessing park green spaces. The MSEE framework is recommended for future policy formulation and provides a flexible operating model applicable to other cities.
In the context of rapid urban expansion and population growth, the spatial inequity of park green spaces' (PGSs) supply and demand has become a research focus. However, few studies have conducted a multi-level comprehensive evaluation of the supply-demand ratio of PGSs at the grid resolution scale. This study developed a multidimensional spatial equity evaluation (MSEE) framework consisting of scale dimensions (local, district, and regional levels) and index dimensions (accessibility, supply-demand ratio, spatial cluster identification). Taking the main urban area of Harbin as an example, we measured the spatial differences between supply and demand for PGSs at various planning levels at a resolution of 500 x 500 m. The results showed serious spatial inequity in supply and demand for PGSs, especially spatial discrepancy among different PGSs. The supply of mini-parks is severely insufficient, and the distribution of comprehensive parks is too concentrated, leading to the polarization of saturated supply and inadequate supply. Some social groups studied in this article, such as older people, rural dwellers, and low-income people, are disadvantaged in accessing PGSs. We recommended that the MSEE framework be used as a reference for future policy formulation. It also provides a flexible operating model that is applicable to other cities.
