轴-辐伺服网络是一种高效的网络类型,有利于降低要素流动成本,提高效率,并发挥规模效应。选取武汉城市圈内37个城镇作为网络节点,利用修正后的引力模型计算其1995—2015年空间联系并进行分析,之后根据联系强度分布构建空间联系网络,并运用Python第三方开源软件包Networkx对其轴-辐网络结构及演化进行评价,得到如下结论:①城市间联系强度逐渐增强,由单极放射状向网状一体化渐次演化,总体联系呈现以武汉主城区为中心的核心—边缘格局。空间联系网络与联系强度同步发育,结构更加致密,同时关键节点的枢纽地位愈发凸显。②关键轴心城镇与联系通道围绕武汉主城区逐步发育,最终形成覆盖武汉主城区东、北...

Hub-spoke network is an efficient network structure, which is helpful for reducing the cost of factor flow, improving efficiency, and increasing scale effect. Hub- spoke network consists of some hubs and spoke, where the hubs play the key role of circulating factors like people, capital, information, and so on, and the spoke receive the factors and transfer them in a specific way so that efficiency would be improved significantly. In this study, we took 37 counties and districts in the Wuhan metropolitan area as the research area and used the modified gravity model to calculate the spatial lin...
