基于空间句法的南阳市中心城区空间演变探析

以南阳市中心城区为例,基于空间句法的理论和方法,建立科学的空间分析模型,分析对比可视化图像和空间形态变量值,总结1955-2015年间南阳市中心城区空间演变的规律和特点。研究发现:城市空间由单一中心向"多中心"城市发展模式递进,以及白河对城市空间结构演变的巨大推动作用;城市主要轴线先为历史城区内的新华东路,之后逐渐转变为南北向的独山大道,并向多轴线共同主导的"自由轮轴"式空间结构发展。

Spatial evolution of Nanyang central city based on space syntax

Defining the central city of Nanyang central city as the subject and basing on the space syntax theory and methods of spatial analysis to establish a scientific model of analysis and comparison of visual images and spatial form variable values, this paper summed up some characteristics and rules of the spatial evolution of Nanyang from 1955 to 2015. The results show that the urban space change from single center to multi center urban development patterns of progressive and the White River plays an important role in urban spatial structure evolution; urban main axis of the first in the history of the city is Xinhua Road, then gradually transit to the north and South Dushan Avenue and the urban space structure become the "liberal hub" type space structure controlled by multi axis.
