Abstract: This paper takes Dujiangyan as the research object due to its characteristics as a mountain tourism city different from other plain cities, and introduces the influence of tourism and mountain attributes on the walking evacuation speed, in order to improve the traditional service radius of emergency shelter. In view of the coexistence of plain and mountain terrain in Dujiangyan Irrigation Project, based on the buffer zone analysis method, the spatial accessibility of refuge places was quantitatively analyzed, and combined with the superposition analysis, the rationality of the spatial layout of refuge places in Dujiangyan Irrigation Project was verified. The results show that there are some unreasonable places in Dujiangyan, such as overlapping shelters, uneven distribution, and exposure of scenic spots outside the accessible range, which need to be further improved.
Keywords: Buffer Analysis, Superposition Analysis, Emergency Shelter, Mountain Tourism City
