摘　　要：山地城市受地形高差限制,步行交通连通性较差,往往导致开敞空间支离破碎。由于地形地质原因,次生灾害发生频率较高。针对山地城市的空间布局特点,分析防灾开敞空间的构成要素,对各构成要素进行初步分类。综合探析影响山地城市防灾空间布局的因素,提出山地城市防灾开敞空间构成及评价标准的差异性,以重庆市长寿区为例,提出山地城市防灾开敞空间的优化策略及适合山地城市自身特征的评价标准,为山地城市防灾开敞空间规划提供理论支持。The restriction of topographical height difference in mountain cities results in the poor connectivity and the fragmented open space. Because of the topography and geology, the frequency of secondary disasters is high. Aiming at the characteristic of spatial layout in mountain cities, it analyzes the elements of open space for disaster prevention and preliminarily classifies each element. Comprehensively exploring the influencing factor of disaster prevention space layout in mountain cities, it proposes the differences of composition and evaluation criteria in open space for disaster prevention in mountain cities. It takes the Changshou district as an example, and puts forward the optimization strategies of open space for disaster prevention in mountain cities and the evaluation criteria fitting for the characteristic of mountain cities. It is expected that it will provide theoretical references for further open space planning of disaster prevention in mountain cities.
