基于哈长城市群11个地级市间的公路、铁路客运与百度指数数据,采用Arc GIS可视化和社会网络分析方法,研究城市空间联系格局和网络结构特征及其影响因素。结果表明,群域内综合联系呈现“下”字型格局,整体联系强度走势与“哈大齐牡”、“长吉图”发展带和哈长发展主轴基本吻合;网络结构特征整体上表现为以哈尔滨、长春为双核心,地理位置越靠近核心,其交通信息通达性越好,对外联系水平越高;群域内城市形成发展的历史因素、行政区边界壁垒、城市综合发展实力、城市功能定位对哈长城市群空间网络结构有一定的影响作用。
Based on the data of highway, railway passenger transport and Baidu index in 11 prefecture-level cities in Harbin-Changsha urban agglomeration, ArcGIS visualization and social network analysis are used to study the characteristics of urban spatial linkage and network structure and its influencing factors. The results show that the comprehensive relationship within the group shows a pattern of “under ”, the trend of the overall contact strength is basically consistent with that of the developmental belt of "DaDa QiMu As a whole, the characteristics are characterized by the dual core of Harbin and Changchun, the closer the geographical location is to the core, the better the accessibility of traffic information and the higher level of external contact; the historical factors of the formation and development of cities within the cluster, the boundary barriers of the administrative regions and the comprehensive development strength of the city , The city function positioning has a certain influence on the cluster structure of the long space in Harbin City.
