【摘要】 铁路作为区域联系的重要通道,其网络的时空效率和公平性影响着区域发展速度和协调性。因此研究将空间句法结合区位熵构建指标计算铁路网络主要城市节点在不同旅行时限内的网络运行效率和公平性,研究发现:(1)效率的提高在一定程度上会导致横向公平性的下降,纵向公平视角下的网络供需情况随旅行时间变化平稳;(2)沪苏浙地区的网络联系效率高于安庆、池州等区域西部地区;(3)南通、盐城、扬州、泰州等地区边缘化明显。更多还原

【Abstract】 As important regional links, the space-time efficiency and fairness of the railway network affect the regional development. Therefore, the study uses spatial syntax with local entropy to construct indicators to calculate the availability of major railway nodes in the railway network in terms of travel time, and measures network operation efficiency and fairness. It is found that:(1) The improvement of efficiency will lead to the decline of horizontal fairness to a certain extent, while from the perspective of vertical fairness,the network supply and demand situation has changed smoothly with time;(2) The network connection efficiency of Shanghai, Jiangsu and Zhejiang regions is higher than that of the western regions such as Anqing and Chizhou;(3) The marginalization of Nantong, Yancheng, Yangzhou, Taizhou is obvious.更多还原
