AHP-Fuzzy assessment of age-friendly public spaces in a mountainous old community
摘要
Amidst global population aging, the age-friendly renovation of public spaces in old urban neighborhoods has become imperative. However, prevailing approaches often prioritize physical upgrades while neglecting the psychosocial and cultural dimensions of elder well-being. To address this gap, this study develops and validates a tripartite assessment model integrating Material Space, Psycho-social Value, and Socio-cultural Environment dimensions. The model employs the Analytic Hierarchy Process (AHP) for weighting indicators and Fuzzy Comprehensive Evaluation (FCE) to synthesize data from behavioral mapping, surveys, and interviews. Applied to a prototypical mountainous former work unit community in Chongqing, the model reveals a moderate overall age-friendliness (score: 3.258/5) characterized by stark contradictions: high perceived safety and social harmony coexist with poor functional diversity, walkability, and severely deficient public participation. Activity concentrates in few nodes, leaving interstitial spaces underused. The findings underscore a compensatory mechanism whereby strong social ties mask underlying deficiencies in accessibility and cultural sustainability. Theoretically, this study advances a contextualized, ‘space-governance-culture’ framework for understanding age-friendliness. Practically, it advocates for diagnosis-driven, synergistic interventions that move beyond cosmetic repairs to foster integrated socio-spatial renewal in aging neighborhoods.
