【摘要】 随着城市化进程的不断推进,交通与城市的关系成为未来区域发展的方向。陕甘宁地区位置特殊,由29个城市作为研究对象构建多指标体系,以熵值法和变异系数法赋予指标权重,通过耦合协调模型对各城市交通可达性与城市活力协同发展进行综合评价,运用ArcGIS软件绘制各个城市交通可达性、城市活力以及两者耦合协调程度的分布图。结果表明:陕甘宁地区交通可达性公路系统比铁路系统更具优势。陕甘宁地区城市活力呈现以西安为中心,兰州为副中心的分布格局,区域整体活力较弱,特别是以酒泉、嘉峪关为主的河西地区,受制于地形限制距离中心城市均较远。在公路和铁路视角下,陕甘宁地区交通可达性与城市综合活力耦合协调处于濒临失调阶段,区域整体协调结果极端化分布。最后,根据以上分析结果试提出相应的发展建议。更多还原

【Abstract】 With the continuous advancement of urbanization, the relationship between transportation and city has become the direction of regional development in the future. With the special location of Shaanxi-Gansu-Ningxia, a multi-index system was constructed with 29 cities as research objects. Entropy method and coefficient of variation method were used to assign weights to the indicators, and a coupled coordination model was used to comprehensively evaluate the coordinated development of traffic accessibility and urban vitality of each city. ArcGIS software was used to map the distribution of traffic accessibility, urban vitality and the degree of coupling coordination of each city. The results show that the road system is more advantageous than the railway system in traffic accessibility in Shaanxi-Gansu-Ningxia region. The urban vitality of Shaan-Gansu-Ningxia region shows a distribution pattern with Xi’an as the center and Lanzhou as the sub-center, and the overall vitality of the region is weak, especially the Hexi area dominated by Jiuquan and Jiayuguan, which is far away from the central cities due to topographic restrictions. From the perspective of road and railway, the coupling coordination between transportation accessibility and urban comprehensive vitality in Shaanxi-Gansu-Ningxia region is on the edge of imbalance, and the results of regional overall coordination are extremely distributed. Finally, according to the above analysis results, the corresponding development suggestions were put forward.更多还原
