| 摘 要： | 基于中原城市群2000,2003,2006,2009年高速公路网络建设情况,分别构建4个年份高速公路拓扑网络分析图和最短路径矩阵,对中原城市群高速公路10年来网络发育程度进行动态分析和空间格局变化的研究。结果表明:2000—2009年中原城市群高速公路网络发育程度明显改善,入网城市和线路数增加迅速,经历了由树状网络—回路网络—网络拓展阶段;区域交通中心形成6路回路网络连接;网络伸展程度逐年提高,区域网络直径变化虽然不明显,但是网络直径对应的城市却发生明显的空间位移;城市群高速公路网络发育在空间上已经开始打破"核心-边缘"的特点,呈现均衡化发展的趋势。

| Abstract: | Based on the highway network construction data for 2000,2003,2006 and 2009,the highway topology network graphs and shortest-path matrixes are built,and then the dynamic analysis of the network development and the study on spatial layout alterations of the highways within the last 10 years in Central China urban agglomeration are performed.The study reveals that highway network development level of Central China urban agglomeration has been improved significantly since 2000 and the amount of both involved cities and roads increase.The development of Central China urban agglomeration experienced the stages of tree net,loop net and net expansion.The study also reveals that the traffic centre has generated six-loops network connections,the extending degree of network are increasing annually.The cities corresponding to the network diameter appear evidently spatial displacement in spite of inconspicuous regional network diameter alterations.The highway network development of urban agglomeration has broken the core-margin model spatially and shown a trend of equalization development. |
