To understand evacuation behavior and psychological characteristics in the event of a sudden fire in an ancient town，and to accurately identify the factors influencing personnel evacuation behavior，a questionnaire survey on evacuation behavior was conducted in an ancient town in Zhejiang Province. The survey focused on three aspects：basic population characteristics，awareness and attitudes toward fire risk in the ancient town，and evacuation behavior. Subsequently，the correlation between evacuation behavior and factors such as age group，frequency of fire drills，and understanding of fire risks in ancient towns was comprehensively analyzed using the Pearson's Chi-square test and eXtreme Gradient Boosting (XGBoost) machine learning algorithm. The results indicate that tourists (77.78%) are more aware of fire risks in the ancient town than local residents and merchants (22.22%). Age has a significant impact on returning behavior. The higher the level of education，the less likely respondents are to engage in overtaking behavior during evacuation (decreasing from 85% to 33%). Individuals who have not proactively familiarized themselves with emergency exits are more likely to exhibit herd and 'habitual' behavior when choosing evacuation exits (increasing from 8% to 33% and from12% to 20%，respectively). Special attention should be given to fire safety training for local residents and merchants. Fire safety management in the ancient town should be strengthened，and evacuation plans tailored to different age groups should be developed to improve evacuation capabilities in the event of a sudden fire in the ancient town.
