摘要
不同城市群高铁运营网络对区域可达性格局的影响不同,其空间公平性特征必然有较大差异,城市群之间的比较非常必要.本文以京津冀、长三角、珠三角三大城市群为例,基于可达性方法,通过定量测度高铁相对可达性、全域空间公平性、空间相对公平性,对比分析三大城市群交通可达性格局和空间公平性的差异.结果表明:(1)三大城市群高铁可达性格局差异明显.京津冀城市群呈孤岛状格局,珠三角城市群呈圈层状格局低,长三角城市群呈多中心格局.(2)全域空间公平性差异较为明显,长三角城市群显著高于京津冀和珠三角城市群.(3)空间相对公平性差异较大.京津冀和长三角城市群相对弱势公平城市居多,珠三角城市群相对强势公平城市占多数;京津冀城市群呈现轴向对称特点,长三角城市群表现出轴带分割特点,而珠三角城市群则再次呈现圈层特点.对三大城市群高铁可达性和公平性格局的对比研究,可为城市群高铁运营网络的优化及其支撑城市群空间发展战略提供思路.
Abstract
The impact of high-speed rail networks on accessibility varies among different urban agglomerations,and the characteristics of spatial-equity will be significant differences.Comparative analysis between urban agglomera-tions is essential.This article taked the three major urban agglomerations of Beijing-Tianjin-Hebei Delta,Yangtze-river Delta,and Pearl-river Delta as examples.Based on accessibility methods,it analyzed the differences in acces-sibility patterns and spatial-equity.The results showed that:(1)There are significant differences in the level and pattern of accessibility.The relative accessibility of Beijing-Tianjin-Hebei Delta forms an isolated-island pattern;The relative accessibility of Pearl-river Delta shows a circular layered pattern;The relative accessibility of Yangtze-river Delta shows a multi-center pattern.(2)The difference of overall spatial-equity is very significant,with Yan-gtze-river Delta higher than Beijing-Tianjin-Hebei Delta and Pearl-river Delta.(3)The differences of relative spa-tial-equity is also significant.Beijing-Tianjin-Hebei Delta and Yangtze-river Delta have more weak-equal cities,while Pearl-river Delta has more powerful-equal cities;Beijing-Tianjin-Hebei Delta exhibits axial symmetry,Yan-gtze-river Delta shows axial belt segmentation,and Pearl-river Delta presents a circular characteristic.The compar-ative study will provide ideas for optimizing the high-speed rail network in urban agglomerations and implementing the spatial development strategy of urban agglomerations.
