This study takes the urban area of Dujiangyan City as the research area, ten risk assessment factors are selected to conduct the fire risk assessment and analysis, including substations, building floor area ratios and miniature fire stations, and uses analytic hierarchy process, buffer analysis and overlay analysis. The minimize facilities model and maximize coverage model in location allocation model (LA model) are used to optimize fire station site selection. The research results show that there are still greater fire risks in the south and northeast of Dujiangyan City. The addition of two small and medium-sized fire stations in the north section of Yanhua road and in south section of Rainbow Avenue can basically realize to cover the areas with higher fire risks thoroughly.
