报告简介：
Global climate change is increasingly recognized as a paramount threat to low-lying coastal cities, which are home to more than half the world's population and concentrate vast economic and infrastructural assets. The Guangdong-Hong Kong-Macao Greater Bay Area (GBA)—a world-class urban cluster—is particularly vulnerable to sea-level rise, recurrent flooding, storm surges, and extreme heatwaves. This vulnerability, compounded by high population density and diverse socio-demographic composition, may trigger climate gentrification by displacing vulnerable populations and altering neighborhood characteristics. Based on a tri-dimensional framework, this study focuses on natural-physical and built environment dimensions to capture the compounding nature of climate risks across the GBA's diverse topography. Using high-resolution spatial datasets—including LiDAR-derived DEM, satellite imagery, hydrological data, climate projection models, and historical hazard records—we model exposures to sea-level rise, urban flooding, storm surges, and extreme heatwaves. Spatially explicit, probabilistic risk index maps are generated, serving as critical inputs for climate gentrification studies and evidence-based adaptation planning.
