Accessibility and Inequality of Park Green Space for Multi-age Distribution in Shanghai, China

Abstract

The accessibility and inequality of public evaluation parks and green spaces are crucial for Shanghai, which is currently experiencing a continuous influx of new population while an aging society still exists. It helps to achieve better social equity in the allocation of parks and green spaces and the formulation and allocation of subsequent planning and construction. This study conducted a multidimensional test on the urban horizontal inequality of driving and walking in different regions and the overall accessibility of the urban park spaces, using two floating-point moving methods, Gini coefficient, and inequality index via ArcGIS and QGIS. The longitudinal evaluation was conducted on five different age groups. The findings shows that in regions with comparatively low traffic and population density, Shanghai's geographic location with the coverage of park green space is generally low. There are different accessibility situations in different areas because of the division of land use and the uneven distribution of green space in parks. Inequality worsens with age, especially in driving modes of transport and inner city areas. Together with theoretical backing and a basis for future planning, this research offers a succinct analysis and comprehension of the existing state of affairs.
