Urgency, Feasibility, Synergy, and Typology: A Framework for Identifying Priority of Urban Green Infrastructure Intervention in Sustainable Urban Renewal

Urban built-up areas confront significant environmental challenges and growing demand for enhanced residents’ well-being. Prioritizing urban green infrastructure (UGI) interventions is crucial sustainable renewal. We propose a six-step framework that integrates urgency, synergy, feasibility, typology to identify UGI intervention priorities. The targets detailed planning units (DPUs) was applied Xi’an, China. First, we assess the risks of supply–demand mismatches related four key ecosystem services (UESs), namely air purification, temperature regulation, runoff recreation. K-means clustering analysis utilized classify risk typology. Next, use dynamic weighting method diagnose urgency comprehensive risk, then evaluate potential synergy optimization between DPUs using local univariate bivariate spatial autocorrelation analysis. proportion renewal land area in employed as an indicator feasibility method. Lastly, adopt TOPSIS priority ranking. Our research reveals 51.7% Xi’an are at high multiple UESs seven types need targeted strategies. ranked top 30 can be selected based on feasibility.
