Abstract
In the context of promoting human-centered sustainable cities and communities, achieving spatial equity in the development of urban public facilities (UPF) plays an essential role and faces a significant challenge. Although the regional and social disparity of UPF's distribution is well documented, researchers seldom consider the spatial distribution disparities between multiple types of UPF and vulnerable groups at a fine scale. This study built a comprehensive evaluation framework with a fine-grained model, which is comprised of grid-based partitioning, multi-source data crawling, cumulative opportunity model, and spatial statistical analysis, to analyze spatial equity in Guangzhou, China. The accessibility to UPF and the social vulnerability index (SVI) are measured utilizing the cumulative opportunity measure and principal component analysis (PCA). This study, therefore, analyzed the imbalance between the distribution of UPF and vulnerable groups. Moreover, the study accurately identified spatial inequity areas using the Gini coefficient and bivariate Moran's I. The results show that numerous areas within the study area have limited opportunities to access UPF. Nevertheless, the formation of multiple urban centers during urbanization has increased the diversity of accessible types of UPF within the community life unit. In addition, due to the aging population in the old city center and the complex population structure of urban villages, the areas in the old town often become high-value clusters spatially with SVI. In particular, due to planning problems caused by urban villages, these areas are often prone to become spatial inequity areas characterized by "high SVI - low comprehensive accessibility." This evaluation framework is user-friendly and suitable for application in other cities, helping to identify spatial inequity areas that require planning intervention and priority.
期刊介绍:
Habitat International is dedicated to the study of urban and rural human settlements: their planning, design, production and management. Its main focus is on urbanisation in its broadest sense in the developing world. However, increasingly the interrelationships and linkages between cities and towns in the developing and developed worlds are becoming apparent and solutions to the problems that result are urgently required. The economic, social, technological and political systems of the world are intertwined and changes in one region almost always affect other regions.
