基于GIS的城市空间布局与轨道交通的协调发展研究

Study on Coordinated Development of Urban Spatial Arrangement and Trail Traffic based on GIS

从城市空间布局对轨道交通的需求肌理出发,利用ArcGIS中的缓冲分析和叠加分析技术,选取影响轨道交通需求的关键因素,对轨道交通和空间布局进行互动关系研究。城市功能中心对轨道交通的需求强度决定了线网布局,且随着距离功能中心距离越远,轨道交通需求强度逐渐减弱。轨道交通与城市功能中心的耦合度越高,二者的协调性也越好。最后对西安市的交通需求强度计算,得出了与城市空间布局耦合度较高的轨道交通线网。

This paper starts from the trail traffic demand mechanism to urban spatial arrangement,utilizes the buffering analysis and overlay analysis of ArcGIS to select the main key factors influencing the trail traffic in urban spatial arrangement,and studies on the interactive relationship between the urban trail traffic and network arrangement.The network arrangement is determined by the trail traffic demand intensity to urban function center,and the trail traffic demand intensity will decrease with the distance to function center increasing.The higher coupling degree of trail traffic and urban function center causes the better coordination.At last,the paper comes to the trail traffic network with higher coupling degree to urban spatial arrangement through the Xi＇an traffic demand intensity calculation.
