摘　　要：本文以都江堰为研究对象,考虑其作为山地旅游城市不同于其他平原城市的特点,引入旅游和山地两种属性对步行疏散速度的影响,改进避难场所传统服务半径。针对都江堰平原、山地两种地形并存的特性,基于缓冲区分析法对避难场所空间可达性定量分析,并结合叠加分析验证都江堰避难场所空间布局的合理性。结果表明,都江堰存在避难场所范围重叠、分布不均、景区暴露在可达范围之外等不合理之处,需要进一步完善。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.
