Abstract: Residents′ awareness of flood risk is an important basis for their evacuation activities. This study focused on exploring the relationship between residents' flood risk perception and their evacuation activities. A questionnaire survey was conducted among 1 300 residents in Harbin City. Then, we clarified the relationship between residents' flood risk perception and evacuation activities by chessboard model. The results showed that the residents in Harbin City had a good perception to flood risk, which increased with the age, educational background, disaster experience, etc. Residents' evacuation activities were affected by their awareness of flood risk, that was, most of the residents took evacuation activities according to the government's refuge warning, less residents' evacuation activities were based on flood risk judgment and few residents' evacuation activities were based on rainfall. The research results could provide reference for residents to form correct flood risk perception, and also provide basis for relevant departments to carry out propaganda and education on disaster prevention and mitigation knowledge.
