摘　　要：城市应急避难场所是韧性城市建设的重要组成部分,其内部空间的可达性影响着防灾功能的发挥和防灾效率。结合相关数据与实地调研,运用基于DepthMap的空间句法理论,量化分析北京国际雕塑公园内部空间的通行可达性和视域可达性。结果得出:公园内部的整体通行可达性呈现出东部高、中部适中、西部低的格局,而视线可达性呈现出中部高、四周低的格局;园内空间多为分散状态,整体性较弱,局部空间难以感知到整体空间,不利于灾时疏散,还有待改善。Urban emergency shelter is an important part of resilient city construction,and the accessibility of its internal space affects the function and efficiency of disaster prevention.Combined with relevant data and field research,the DEPthMap based on space syntax theory is used to quantitatively analyze the accessibility and visual field accessibility of the inner space of Beijing International Sculpture Park.The results show that the overall accessibility in the park is high in the east,moderate in the middle and low in the west,and the line of sight accessibility is high in the middle and low around the park.The space in the park is mostly scattered,the integrity is weak,and the local space is difficult to perceive the overall space,which is not conducive to disaster evacuation,and needs to be improved.
