Abstract: Taking residents in flood storage and detention areas in Hebei Province as the research object, based on questionnaire survey data, the perception and adaptability characteristics of residents towards flood disaster risks in flood storage and detention areas were analyzed. Linear regression analysis was used to analyze the influencing factors of residents' risk perception in flood storage and detention areas. The results show that: ①Residents' lives and properties are exposed to certain flood risks; ②The overall level of risk perception of residents in the flood storage area is high, and there are differences among residents' groups, and the risk perception of residents in different flood storage areas is different; ③The adaptive behaviour of residents in the flood storage area is divided into their own active adaptation and passive adaptation guided by the government. The relationship between the intensity of disaster risk perception and adaptation is not a simple positive correlation; ④The influencing factors of the risk perception of residents in the stagnant flood zone are mainly age, disaster experience, the degree of understanding of the stagnant flood zone, the degree of understanding of emergency response knowledge, the government's trust, and the degree of attachment to the place of residence. Based on the results, a few suggestions are provided to the residents and relevant departments to enhance the residents' risk perception ability, reduce disaster losses and optimise disaster prevention and mitigation work.
