Abstract: With the improvement of industrialization and the development of science and technology, the fre-quency of global meteorological disasters is increasing. The effects of climate change have threatened human existence. For some economically underdeveloped countries, this impact may increase national vulnerability[1]. So climate change has evolved from a environmental issue into an economic and political one. Measuring the vulnerability of a country is essentially a kind of evaluation problem. Therefore, we propose a multi-level fuzzy comprehensive evaluation model. Firstly, we use analytic hierarchy process (AHP) to determine the weight distribution of each factor.  Secondly according to the collected data, we use statistical analysis to solve the correlation between climate change and national vulnerability,  and display the results in the image.
