基于空间句法的城市防灾公园空间可达性分析——以苏州桐泾公园为例

Spatial Accessibility Analysis of Urban Disaster Prevention Park Based on Space Syntax:A Case Study of Tongjing Park in Suzhou

防灾公园是城市防灾避难的重要基础设施,内部空间的可达性对其防灾功能的有效性和防灾效率最为重要。该研究以苏州桐泾公园为研究对象,根据人群平时与灾时空间活动的不同,通过空间句法专用分析软件Depthmap对城市防灾公园空间分别进行视线可达性和通行可达性分析,量化研究桐泾公园防灾避难空间的通行与视线可达性差异,并基于结果对桐泾公园防灾避难空间布局提出建议,为城市防灾公园的空间组织提供新的角度与方法,为防灾避难公园规划设计及改造提供借鉴。

Disaster prevention park is an important infrastructure for disaster prevention in cities.The accessibility of internal space has the most important influence on the effectiveness of its disaster prevention function and the efficiency of disaster prevention.This study took Suzhou Tongjing Park as the case to analyse the sight accessibility and traffic accessibility of the urban disaster prevention park space using the spatial syntax special analysis software Depthmap with the consideration on the differences of people s space activities between the disaster and non-disaster periods,and made the quantitative study of the difference between the sight and traffic accessibility.Based on the results,the suggestions were proposed for the layout of disaster prevention and shelter space in Tongjing Park.This study provides a new perspective and method for the spatial organization of urban disaster prevention parks,and also provides references for the planning,design and transformation of disaster prevention and shelter parks.
