城市韧性差异下居民生计韧性对防灾减灾行为影响研究OA

Flood disasters are among the most frequent natural hazards in China,causing substantial econom-ic losses and casualties.In response to the current gaps in China's flood risk management—namely,the lack of intersection between urban resilience and residents'livelihood resilience research,and the disproportionate em-phasis on urban residents while neglecting their rural counterparts—a flood-prone area in Sichuan Province is taken as a case study.Grounded in the Man-Land Relationship Theory and the Sustainable Livelihoods Analysis Framework,an analytical framework is constructed as"urban resilience → livelihood resilience of urban and rural residents → disaster preparedness and mitigation behaviors"to investigate the relationship between resi-dents'livelihood resilience and their disaster response actions under varying levels of urban resilience.The re-sults show that urban resilience across Sichuan Province increased continuously from 2013 to 2023,presenting a central-east-west gradient decreasing spatial pattern centered on Chengdu,with its evolution primarily con-strained by social and economic factors.Urban and rural residents'livelihood resilience rises alongside the im-provement of urban resilience,and urban residents generally attain higher livelihood resilience than rural resi-dents.At equivalent livelihood resilience levels,the proportion of rural residents taking disaster prevention and mitigation behaviors is higher.Rural residents'livelihood resilience exerts a significant positive effect on the di-saster prevention and mitigation behaviors,whereas no significant effect is detected for urban residents.In terms of control variables,rural residents'gender,physical health condition,whether they are the main household care-giver,and the severity of the disaster all have significant impacts on their adoption of disaster prevention and miti-gation behaviors.Policy references for flood risk management and the construction of resilient disaster preven-tion systems are provided in this study.
