Abstract: Residents′ risk perception of disasters is important in the implementation of disaster prevention and mitigation. Based on the KAP (Knowledge, Attitude, Practice) model, we constructed an evaluation index system for flood risk perception of Chinese residents from aspects of knowledge, attitude and behavior. The data were obtained from online questionnaires. Index weights were calculated by using order relation analysis method. The flood risk perception index was constructed to evaluate the residents' risk perception level. The results showed that:① Chinese residents are most positive in attitude towards floods, with an average score of 7.84; they score 6.45 in taking risk-averse measures in response to the threat of flooding; and they knowledge of floods tend to be scarce, with an average score of 6.28. ② Residents’ perception level of flood risk is unsatisfactory, with a score of 7.83; most of the survey samples are in the low to medium levels, accounting for 36.50% and 46.01% of total samples. It is suggested that the government should reinforce publicity, education and emergency drills; the community should prepare for disaster prevention and mitigation, and make contingency plans; residents should pay attention to flood information and learn knowledge on flood control and disaster reduction.
