【摘要】："流"空间成为大数据时代人文地理学研究的重要内容之一。基于东北地区2005年、2010年及2015年铁路客运班列数据,利用社会网络分析方法,从总体规模、网络密度、城市中心性、凝聚子群等方面对东北地区城市网络结构演变进行分析,并对其空间组织模式选择进行相关探讨。结果表明:(1)铁路客运联系经历了普列主导、高铁萌芽及高铁繁荣等三个阶段,始发列车视角下城市等级体系的初级首位型分布特征明显、"一轴双核"地位相对稳固;(2)区域城市网络密度虽得到一定提升但仍处于较弱连接状态、演变进程中出现"马太效应",辽吉省际联系紧密、黑蒙(东)边缘化倾向明显;(3)城市程度中心度出现两极分化现象、高值区地域集聚特征显著,核心城市效应由极化向扩散转变、大连网络核心地位逐步确立;中介中心度高值区总体出现跃迁现象,其中哈尔滨中介效应稳固、部分核心城市的空间遮蔽范围持续缩小;(4)东北地区城市网络小团体现象明显,区域整合进程下的"四片区"格局逐步稳固,哈大轴线子群成为网络联系的核心组团;(5)基于城市个体特征及网络整体结构分析,提出东北地区的"圈层推进—轴辐拓展—组团分区"的空间组织模式。
[Abstract]:"flow" space became one of the important contents in the study of human geography in big data's time.Based on the class data of railway passenger transport in Northeast China in 2005, 2010 and 2015, the evolution of urban network structure in Northeast China is analyzed from the aspects of total scale, network density, urban centrality, agglomeration and so on, using social network analysis method.And to its spatial organization mode choice carries on the correlation discussion.The results show that the railway passenger transport link has gone through three stages, namely, the leading role of the general train, the sprout of high-speed rail and the boom of high-speed rail.Under the angle of view of the starting train, the primary first type distribution of the urban grade system is obvious, and the status of "one axis and two nuclei" is relatively stable. (2) although the density of the regional urban network is improved to a certain extent, it is still in a weak connection state.In the process of evolution, the "Matthew effect" appeared, the inter-provincial ties between Liaoning and Jilin were close, and the tendency of marginalization of Black Mongolia (East) was obvious. (3) the centrality of urban level appeared polarization phenomenon, and the regional agglomeration characteristics of high value region were obvious.The core urban effect changes from polarization to diffusion, the core status of Dalian network is gradually established, the transition phenomenon appears in the high value area of intermediary center in general, and the intermediary effect in Harbin is stable.(4) the phenomenon of urban network small groups in Northeast China is obvious, and the pattern of "four districts" in the process of regional integration is gradually stable.Based on the analysis of the individual characteristics of the city and the overall structure of the network, this paper puts forward the spatial organization model of "circle push, axis-radial extension-cluster partition" in Northeast China.
