【摘要】 针对传统研究中城市空间演变的历史阶段划分依据和方法的问题,利用城市历史地图数字化后的资料平台,运用紧凑度指数、空间整合度指数和分形指数的相关原理,基于GIS、空间句法等相关技术,对城市建成区范围、路网结构、街区肌理等典型系统的空间演变过程进行定量化的数字模拟分析,探寻城市空间演变中不同系统的几何或数字逻辑关系与城市空间整体格局变化的关联,进而确定城市空间特色的自组织规律节点。并以天津中心城区为例,实证了相关方法在城市空间演变历史阶段划分中的应用。更多还原

【Abstract】 In order to find the evidence of history stage division of urban space evolution,this article takes advantage of the platform of digitalized historic maps and carrys on quantitative digital simulation analysis for the special evolution process of typical systems such as the scope of urban built-up areas,road network structure,block texture by applying compact index,spatial integration index and the relevant principles of fractal index,based on GIS and Space Syntax technology.The article also gives method of ascertaining the characteristic nodes of evolution and self-organization of urban space after exploring the connection between the geometry or digital logic relations in different systems and the change of urban space as a whole pattern.This research demonstrates these related methods in practice in historical stage division of urban spatial evolution,taking Tianjin as an example.更多还原
