基于空间句法的历史文化街区空间形态研究——以济南明府城为例

Research on Spatial Morphology of Historical and Cultural Blocks Based on Space Syntax--A Case of Mingfucheng in Jinan

济南明府城较为完整地保留了济南传统历史风貌,是具有济南历史特色的标志性区域。本文通过空间句法(depthmap)对其整合度和选择度进行分析,并且借助济南明城府商业POI数据在地理信息系统(ArcGIS)中进行核密度估算,探究其空间形态。从而得出:济南明府城呈现出整体和局部相协调的空间形态,其由四周开放的城市主干道和较为私密的街区内部街巷构成,空间结构体系层次内外分明,较为合理。明府城内各街道中商业区的选择度和整合度较高,居住区则较低,商业区与居住区呈现鲜明对比。

Jinan Mingfucheng retains the traditional historical features of Jinan completely and is a landmark area with Jinan historical characteristics.In this paper,the integration degree and selectivity degree are analyzed by spatial syntax(Depthmap),and the kernel density is estimated by ArcGIS with the help of Jinan Mingchengfu commercial POI big data,and the spatial morphology is explored.It is concluded that Jinan Mingfucheng presents a coordinated spatial form of the whole and the part,which is composed of the open urban main road and the more private inner streets of the block.Its spatial structure system has distinct levels inside and outside,which is reasonable.In Mingfucheng,the degree of choice and integration of the commercial district is high,while the residential district is low,showing a sharp contrast between the commercial district and residential district.
