摘要
城市轨道交通系统对自身各站点有显著的“时空压缩效应”,但对城市其他节点的“时空压缩效应”尚不明确,同时栅格距离成本法对市区小空间尺度可达性测算也需要进一步实证尝试;乌鲁木齐市作为新建城市轨道交通的典型城市可以较好地检测以上2个方面的问题。基于栅格成本距离法对有无城市轨道交通2种背景下乌鲁木齐城市可达性和经济联系进行测量,结果表明,城市轨道交通对城市内各关键节点形成明显的“时空压缩效应”;城市轨道交通系统在强化经济联系性强的区县关系的同时,也进一步加大城市内各区县经济联系两极化趋势;城市轨道交通系统的搭建,将进一步扩大城市经济核心地区的经济联系优势,使得其他地区对该类地区的经济指向性进一步加强。
The urban rail transit system has a significant space-time compression effect on each station but an unclear space-time compression effect on other nodes of the city. Meanwhile, the grid distance cost method also needs further empirical attempts to calculate urban accessibility on a small spatial scale. As a typical city with newly built urban rail transit, Urumqi can be used to analyze the above two problems. By utilizing the grid distance cost method, this paper measured the urban accessibility and economic linkage in Urumqi with and without urban rail transit. The results show that urban rail transit can cause an obvious space-time compression effect on key nodes in the city. The urban rail transit system not only strengthens the relationship between districts and counties with strong economic linkage but also intensifies the polarization trend of economic linkage among districts and counties of the city. The construction of an urban rail transit system will further expand the economic linkage advantage of urban economic core areas so that the economic orientation of other regions to such areas will be further strengthened.
