Spatio-Temporal Characteristics of Public Disaster Perception and Its Influencing Factors from the Perspective of Urban Ergonomics
摘要
Abstract
In recent years,there has been a surge in the frequency of extreme weather events globally.As one of the primary urban disaster-affected entities,the public expresses their subjective perceptions of the disaster processes through social media platforms such as Weibo,profoundly reflecting and influencing the emergency responses and disaster developments.Consequently,investigating public disaster perception from the perspective and methodologies of Urban Ergonomics holds significant implications for enhancing urban resilience.This study utilises Weibo data from the Typhoon"Mangkhut"in Shenzhen during September 2018 as a case study.Employing the Latent Dirichlet Allocation(LDA)model for text clustering and the SnowNLP model for sentiment analysis,the research derives public disaster thematic perceptions and emotional sentiments.Through spatial clustering using the Density-Based Spatial Clustering of Applications with Noise(DBSCAN)algorithm,the spatio-temperal distribution features of public disaster perceptions are summarised.Furthermore,the study explores factors influencing the characteristics of public disaster perception from two perspectives:the physical built environment and public social attributes.The findings reveal distinctive characteristics of public disaster perception under extreme weather conditions and establish associations between these perceptions and the built environment and social attributes.This research serves as a guide for urban resilience planning and design in the context of extreme weather events.关键词
