摘要

印度南部的老城镇在应对快速城市化带来的形态变化方面面临重重困难。本研究从火灾发生时紧急疏散的角度出发，根据街道网络的连通性、整合性和深度这三个参数来了解坦贾武尔老城的形态构造，并使用 UCL DepthmapX 仿真和 Space Syntax 来分析连通性和网络程度。连通性与一体化之间的回归分析表明，西部地区的相关值为 0.2757（R2=0.076）。南部地区的相关值为 0.3592（R2=0.129）。东部地区的相关值为 0.3975（R2=0.158），北部地区为 0.2302（R2=0.053）。结果表明，坦贾武尔镇北部和西部地区的可懂度较低，在火灾灾难疏散时容易受到影响。

Vulnerability Analysis of Fire Disaster Evacuation at old Thanjavur town, India using Space Syntax Method

Old towns of south India face difficulties to cope up with morphological changes due to rapid urbanization. This research understands the morphological configuration of old Thanjavur town based on three parameters: connectivity, integration and depth of street networks from the aspect of emergency evacuation in the event of a fire disaster.UCL DepthmapX simulation and Space Syntax are used to analyze the degree of connectivity and network. Analysis for regression between connectivity and integration shows correlation value of 0.2757 (R2=0.076) in western zone. The southern zone shows a correlation value of 0.3592 (R2=0.129). The correlation value of eastern zone is 0.3975 (R2=0.158) and in northern zone it is 0.2302 (R2=0.053). Result shows low levels of intelligibility in northern and western zones of Thanjavur town which are vulnerable in the event of fire disaster evacuation.
