People-Oriented: A Framework for Evaluating the Level of Green Space Provision in the Life Circle from a Supply and Demand Perspective: A Case Study of Gulou District, Nanjing, China

Abstract

Green space resources, in the context of urbanisation, cannot meet the actual needs of residents well, and the study of the balance of green space resource allocation based on the relationship between supply and demand is an urgent problem to be solved. This study quantitatively evaluates the green space supply level from four dimensions by constructing a framework for assessment in the community life circle. It also evaluates the matching of green space supply and demand, resource distribution fairness, and distribution equilibrium under group differentiation through the supply–demand coupling matrix, the Gini coefficient, and the Kruskal–Wallis H non-parametric rank-sum test, respectively. This study shows that: (1) A significant spatial imbalance exists in green space resource allocation in community life circles in different dimensions. (2) The comprehensive green space supply level in the community life circle matched the total demand of residents to a low degree. (3) There was significant inequality in green space resource allocation within the community life circle (the Gini coefficient of each evaluation perspective was >0.4). Based on the study results, we were able to identify community life circles with spatial mismatches, different supply and demand, and other green space resource allocation problems, which is of great significance to urban green space research and planning practice under the ‘green justice’ framework.

Resident Preferences for Urban Green Spaces in Response to Pandemic Public Health Emergency: A Case Study of Shanghai

“…The pandemic has heightened the demand for green spaces within walking distance. However, the reality is that there is an obvious spatial imbalance in the distribution of green space resources, making it difficult to meet the needs of community residents [82]. There are two main challenges impede the efficient utilization of these spaces in Shanghai: the uneven distribution of UGS in the city requires many residents to drive instead of walk to access green spaces [83]; restrictive measures during outbreaks, such as lockdowns and quarantines, limit the use of these spaces to prevent mass gatherings and transportation constraints [84].…”

Multidimensional Spatial Vitality Automated Monitoring Method for Public Open Spaces Based on Computer Vision Technology: Case Study of Nanjing’s Daxing Palace Square

“…Humanistic and precise planning and transformation have become mainstream approaches, supplanting "the grand narrative" concept in urban spatial planning and construction [7]. This necessitates researchers to macroscopically monitor urban accessibility and the physical environment while microscopically re-evaluating public open spaces from the humancentric perspective [8][9][10][11][12][13]. Based on Jacobs' humanistic urban studies [14], numerous researchers have emphasized the importance of crowd behavior to assess spatial vitality in public open spaces.…”

Identification of Critical Areas of Openness–Vitality Intensity Imbalance in Waterfront Spaces and Prioritization of Interventions: A Case Study of Xiangjiang River in Changsha, China

“…Meanwhile, rapid urbanization has led to the development of urban waterfront spaces, facing severe challenges [14][15][16], such as the decline in ecological quality, low accessibility, and limited service functions. All of these factors are detrimental to the concentration of spatial vitality in the city [17,18]. The above problems reflect the irrational allocation and even waste of spatial resources, which, if not constrained by planning, will inevitably cause the degradation of the quality of urban waterfront open spaces and the dissipation of vitality.…”
