Vulnerability Assessment of Tropical Cyclone Disasters:A Case Study of 19 Coastal Districts in Bangladesh
摘要
Abstract
Bangladesh is one of the countries most severely affected by tropical cyclone disasters worldwide.Systematically identifying the spatial distribution patterns and driving mechanisms of vulnerability is critical to enhancing disaster prevention and mitigation capacities in its coastal areas.This study assesses tropical cyclone disaster vulnerability across 19 coastal districts of Bangladesh by constructing a vulnerability assessment framework based on three dimensions:exposure,sensitivity,and adaptive capacity to characterize the spatial distributions of vulnerability and key driving factors.The results indicate that the spatial pattern of vulnerability across the districts is characterized by higher levels along the eastern coast and lower levels along the western coast,with Chattogram district exhibiting the highest vulnerability and representing a priority area for disaster prevention and mitigation;Vulnerability factors display spatial heterogeneity,with exposure generally decreasing from east to west,while sensitivity and adaptive capacity tend to decrease from west to east;The contribution analysis shows that vulnerability on the western coast areas is mainly driven by sensitivity and adaptive capacity factors,on the central coast by adaptive capacity,and on the eastern coast predominantly by exposure factors,and several regions are characterized by the combined influence of multiple vulnerability factors.This research provides a scientific basis for designing targeted disaster risk reduction strategies in the coastal regions of Bangladesh.关键词
