高铁网络对西北城市旅游经济联系的空间影响

Spatial Effect of Lan-Xin High-speed Rail to the Northwest City Tourist Traffic Pattern

基于GIS平台,以城市间的最短旅行时间和"小时经济圈"及国内旅游收入、国内旅游人数等数据为基础数据,通过可达性、修正引力模型等指标,分析了兰新高铁开通前后沿线各城市旅游交通格局变化特征,结果表明:(1)兰新高铁提升了沿线城市旅游交通的可达性;(2)兰新高铁带来了旅游交通格局的变化,显示出兰州为高铁线路东翼核心、嘉峪关为中翼核心、乌鲁木齐为西翼核心、东中西三翼相互抱团的空间特征;(3)兰新高铁加速了旅游业的发展,沿线城市旅游经济受高铁带动明显;(4)兰新高铁缩短了起止点城市的距离,更拉近了沿线比邻城市间的距离,催生同城效应,形成多个1 h旅游经济圈。

In view of the impact of high-speed rail on the urban tourist traffic pattern along the line,based on the GIS platform,the shortest travel time,the hour economic circle,the domestic tourism income and the number of domestic tourist data,effects of new high-speed railway on city tourism pattern along the traffic is analyzed through accessibility,modifying the gravity model and other model.The result showed that Lan-Xin high-speed rail improved the traffic accessibility of the whole city tourism along the line;The Lan-Xin high-speed rail brought tourism traffic pattern changes,and show features of three wings and mutual unity space characteristic;The high-speed rail accelerated the development of tourism industry along the line,and city’s traveling economy was obviously aroused by high speed railway;An opening of high speed rail,to a certain extent,accelerated the development of regional tourism along the line,day trip significantly increased between the cities.
