Research on the Impact of Climate Change on the Fragility of a Country Based on Analytic Hierarchy Process

[摘要] National fragility can reflect a country's level of development, potential wind risks, and is crucial for the country to formulate future development strategies. This paper uses the Analytic Hierarchy Process to establish a fragility evaluation index system based on social factors, economic factors, political factors, and climate factors, and obtains the weight values of the four factors. It uses the Likert five-point method to predict the degree of national stability, and then analyzes the country's Fragility index. The analysis shows that climate factors have a large weight and are uncontrollable factors, which have an important impact on the country's fragility. Taking Bangladesh as an example to analyze the impact of climate change on the country's fragility, analyze the total score of the country's stability assessment when climate factors are not considered and considering climate factors. The results show that the degree of national fragility in Bangladesh is affected by climatic factors. Larger. This study will provide relevant evidence for the analysis and application of national fragility assessment.
