Abstract

As global climate change intensifies, extreme rainfall and flooding increasingly threaten urban safety, significantly impacting public emotions during disasters. Green infrastructure (GI), a vital component of urban resilience, effectively alleviates urban flood pressures while enhancing adaptability and recovery. However, existing research often overlooks the impact of urban resilience on public perception. This study innovatively introduces the concept of “Public Emotional Recovery” (PER) as a temporal process from disaster to normalcy, exploring how GI morphological resilience influences PER. Based on the 4R resilience framework, the study establishes a Urban Green Infrastructure Morphological Resilience (UGIMR) evaluation system to analyze how GI morphology in disaster recovery within the urban built environment morphology impacts PER. Using the extreme rainfall caused by Typhoon Haikui's remnants in Shenzhen (September 2023) as a case study, social media data and three PER indicators reveal emotional recovery patterns. Combined with built environment data, ArcGIS, and landscape patch analysis, key factors influencing PER were identified through correlation analysis. Results indicate that accessibility and resourcefulness are the most significant 4R dimensions affecting PER, with GI morphological resilience playing a central role. Contiguity Index(CONTIG_AM), Number of Patches(NP), Landscape Type Richness ( N type ) , and Aggregation Index(AI) positively influence PER, while Patch Connectivity(CONNECT) and Patch Density(PD)have negative effects. This study validates core theories on GI morphology's impact on PER, offering theoretical insights and practical guidance for post-disaster urban planning, resource allocation, and GI design.
