Typhoon Compound Disaster Risk Assessment and Coping Strategies for Haikou City

This study takes Haikou, a typical tropical coastal city, as its research object. Using the H-E-V framework and multi-source geospatial data, it assesses typhoon compound disaster risks. Results show significant spatial differentiation, with an overall “high along coast, low inland” pattern. Based on the assessment, spatial planning strategies are proposed across macro, meso, and micro levels to inform disaster prevention and climate-adaptive governance for high-density coastal cities.
