Abstract: Higher reserve willingness can significantly improve the reserve level of family emergency supplies and the response ability to family natural disaster. Taking Sichuan Ganzi Tibetan Autonomous Prefecture as an example, this paper analyses the willingness of family emergency material reserve in Tibetan areas through questionnaire survey, correlation analysis and regression analysis, aiming to explore the factors affecting family reserve willingness, and then put forward corresponding countermeasures and suggestions. The study shows that the number of elderly or children, the firmness of family houses and the annual income of families are significantly negatively correlated with the willingness of families to reserve emergency materials for natural disasters, but there is a significant positive correlation between the number of livestock owned by families and the willingness of families to reserve emergency supplies. The paper puts forward that the willingness of family emergency material reserve can be improved by regularly carrying out disaster knowledge education and increasing financial subsidies.
