Abstract
Urban green spaces are conducive to people’s physical, mental, and social health; however, in many cases, these benefits are unevenly distributed in cities. This study explored the equity of urban green spaces in terms of accessibility and spatial morphology, specifically, (1) applied the geographic information system (GIS) accessibility index to the equity of parks in Fuzhou City; (2) discussed the accessibility of parks and the spatial morphological characteristics of streets from a space syntax analysis; (3) examined the correlation between the accessibility of parks in Fuzhou City and the spatial morphology of streets. The results provide a valuable reference for sustainable urban design and planning.
Highlights
Sustainable development has been studied from environmental, economic, and social aspects
Accessibility takes into account land use, transportation, time, and personal factors to different degrees; accessibility has been widely adopted by researchers of spatial equity
The calculated spatial Gini coefficient of community accessib0.i5l0ity is 0.7, and the calculated spatial inequality index of road segment accessibility is 0.29384, which 0i.m40plies that calculating accessibility by street segments can output a more fair result, while spatial units based on community accessibility produce less fair space. 0.30
Summary
Sustainable development has been studied from environmental, economic, and social aspects. Few researches have addressed the street network of cities from a global perspective or studied whether the characteristics of urban morphological structures are related to the development of urban public facilities. The political and ethnical reasons for unfair facility distribution were discussed [24]; urban morphology was rarely addressed due to the differences in access or convenience to public facilities in different areas, as generated by street and texture planning. The analysis of spatial equity should regard the road network structure as the foundation of an urban environment system, which provides a fair starting point for different groups in different areas to access public services. This study analyzed whether residents have equal opportunity to access existing public facilities according to the texture of the urban road networks from the perspective of spatial equity. From an empirical perspective, the case study can guide decision-makers in sustainable urban development and urban space optimization
