Individuals' disaster preparedness may indirectly affect their quality of life through the way they perceive risk. Based on the revised Protective Action Decision Model, using a survey of 327 households in the hardest-hit areas of the Wenchuan and Lushan earthquakes, this study has used the ordinal multi-class logistic regression model to analyze the correlation between farmers' disaster preparedness and their quality of life, and, further, to test the mediating effect of disaster risk perception between disaster preparedness and quality of life. The results show that: (1) disaster-preparedness behavior has a significant positive effect on individuals' happiness, life satisfaction, and general health; (2) compared with farmers who have not prepared for disasters, farmers who have prepared will perceive a lower disaster risk; (3) as for the general health of individuals, the perception of the possibility of disaster is an intermediary factor for the impact of disaster preparedness on quality of life. Policymakers should consider improving people's quality of life by changing their disaster-preparedness behaviors, thus improving their well-being.

个人的备灾工作可能会通过感知风险的方式间接影响他们的生活质量。在修订后的保护行动决策模型的基础上，通过对汶川和庐山地震最重灾区的327户家庭进行调查，本研究使用有序多类Logistic回归模型来分析农民的防灾能力与它们的生活质量，并进一步测试灾害风险感知在灾难准备和生活质量之间的中介作用。结果表明：（1）备灾行为对个人的幸福感，生活满意度和整体健康有显着的积极影响；（2）与没有备灾的农民相比，有备灾的农民感知到的灾害风险更低；（3）关于个人的整体健康，对灾难可能性的认识是灾难准备对生活质量的影响的中介因素。决策者应考虑通过改变人们的备灾行为来改善人们的生活质量，从而改善他们的福祉。
