基于功能性联系的山东半岛城市群空间范围划定实证研究

基于多元流数据,运用GIS空间分析、社会网络分析和可达性分析等多种研究方法,从市域和县域尺度揭示了山东省地域间联系特征与结构,并划定了山东半岛城市群空间范围。研究表明:在企业流,山东半岛城市群呈现出核心边缘特征,县域尺度城市群空间范围小于城市尺度;在公路客运流,以济南为中心的高密度交通网已基本形成,各地区间联系均较为密切;在铁路客运流,高速铁路沿线地区可达性普遍较好并成为了城市群构成单元;基于多元流数据综合划定的城市群空间范围更接近其实际发育程度,并且以山东半岛城市群为例的实证分析为城市群空间范围划定研究提供有益探索。

Spatial Scope of Shandong Peninsula Urban Agglomeration Based on Functional Urban Connection

Based on the multivariate flows data,this paper uses social network analysis,GIS spatial analysis,accessibility analysis and so on to reveal characteristics and structure of urban network and demarcate spatial scope of Shandong Peninsula Urban Agglomeration from the scale of city and county.The results are presented as follows:1)In the enterprise flow,Shandong Peninsula Urban Agglomeration presents the core edge characteristic and the county scope of it is smaller than that of city.2)In the highway passenger transport flow,the high density transportation network centered on Jinan has basically formed and all areas are closely contacted in urban agglomerations.3)In the railway passenger transport flow,the accessibility of areas along high-speed railways is generally better and has become an important unit of urban agglomerations.4)The spatial scope based on multivariate flows data is closer to the actual development level of urban agglomerations,and the empirical analysis based on the Shandong Peninsula Urban Agglomeration is a useful explorations for the delineation of urban agglomeration spatial scope.
