Analysis on the Vulnerability of Natural Disasters in Coastal Cities and Assessment of the Construction of Flexible Cities

Abstract

— With the expansion of urban population and economic development, the hidden dangers of disasters are increasing, and the disaster factors are constantly expanding and intensifying. Especially in coastal cities, because of the interaction between climate and land and sea, coastal cities are both pregnant and disaster-bearing. The National Plan for Comprehensive Disaster Prevention and Mitigation (2016-2020) states that the complex and volatile disaster situation in China and the weak foundation for disaster prevention and reduction require us to take a long-term, holistic and changing view of urban development. We will continue to improve the ability of cities to adapt to and transform against natural disasters and risks. Therefore, the study on the vulnerability and resilience of coastal cities to natural disasters is of great significance to improve the resilience and resilience of cities.
