基于空间句法的黄州城区形态发展与优化

Morphology Development and Optimization of Huangzhou Urban Area Based on Space Syntax

基于1995、2005、2013年3个时期的黄州城区路网,将Axwoman6.0系统嵌入GIS通用技术平台,运用空间句法中的轴线地图分析,以整体集成度和局部集成度建立不同时期的城市空间协同度,对黄州城区的城市空间进行量化比较分析,探讨路网格局和城市形态的相互关系。结果表明:黄州城区的整体集成度高值区由"轴"到"面",不断扩大;空间协同度总体较高,但呈下降态势。城市表现出核心扩大化、空间复杂化、形态无序化的特征,进而指出黄州区存在单中心的城市结构以及城市形态日趋混乱的问题。据此,提出黄州区在今后的发展应注意培育多个中心,分散城市核心的职能;合理规划交通体系,带动周边联动发展;科学布局城市用地,扭转混乱发展态势。

Based on the urban road network of Huangzhou in 1995, 2005 and 2013, through axis map analysis of space syntax and embedding Axwoman 6.0 system into GIS general technical platform, this paper establishes spatial synergy degree of city in different periods from global integration values and local integration values and discusses the relationship between the road network pattern and urban morphology. The results show that： The high diagram of global integration region of Huangzhou urban area extends continuously from ＂axis＂ to ＂area＂; The urban space has a high synergy degree as a whole, with a downward trend; urban morphology shows core-expanding, spacecomplicating and form-disordering characteristics. We argue that Huangzhou＇s problems are： single-center structure and increasingly chaotic urban morphology. Therefore, we put forward some suggestions for the development of the city as follows： 1） More centers should be built to release the function of urban core; 2） Traffic system should be planned more reasonably to promote the development of surrounding districts; 3） Urban land use should be planned more scientifically to reverse the chaotic development trend.
