山区城市地质灾害韧性影响因素及提升策略研究OACHSSCD

To help mountain cities strengthen their resistance,adaptation and recovery capacity against geohazards and raise their o-verall disaster resilience,this paper took Luding County—hit by the Ms 6.8 earthquake—as the study area and applies the DEMATEL-ISM method to systematically analyse the intensity,hierarchical structure and action paths of the factors that govern urban geohazard resilience in mountainous regions.The main findings were:(1)Urban geohazard resilience in mountain areas was essentially shaped by seven critical factors:economic level,institutional optimisation,emergency plans,emergency-command capacity,disaster-prevention funding,risk-management capacity and rescue capability.(2)Two transformation channels existed:an"economy-material-capaci-ty"route and an"institution-management-capacity"route.(3)The resilience system is an organic whole formed by the coupling of the economic base and top-level institutional design,an intermediate transmission-coordination hub,and front-line execution-on-site response.
