长距离高铁对沿线城市旅游经济联系的空间影响及角色分析——以兰新高铁为例

在GIS技术支持下，基于旅游交通可达性视角，构建旅游经济联系模型，运用社会网络分析方法，确定沿线城市在旅游经济联系网络中的角色，结果表明：高铁时空压缩效应促使沿线城市旅游交通可达性和旅游经济联系普遍提升，但提升幅度具有空间差异性，廊道东侧城市优于西侧城市，各省区旅游经济基础较好城市优于基础较差城市；旅游网络结构日趋紧密，城市间旅游互动与合作逐渐频繁，区域旅游经济联系呈现协调发展趋势。深入剖析9个城市的网络角色对兰新廊道旅游空间发展模式提出相关建议：沿线地区应充分发挥乌鲁木齐、兰州核心城市的功能，同时利用酒泉次核心的集聚与扩散作用，发挥嘉峪关、张掖、西宁重要旅游目的地的承转作用，带动吐鲁番、海东、哈密等边缘城市，打造西北“旅游+高铁”丝绸之路黄金线。

Spatial effect of long distance high speed railway on tourism economic link and role analysis of cities along the railway:A caseof Lanzhou Xinjiang high speed rail

The Lanzhou Xinjiang high speed railway is one of the longest high speed railway in the world,running through several provinces in northwest China.The spatial evolution of urban tourism traffic accessibility and tourism economic linkages along the Lanzhou Xinjiang high speed railway before and after the opening of Lanzhou Xinjiang high speed railway is measured by using the inverse distance weighted difference technique of GIS.The role of cities along the railway in the tourism economic linkages network is analyzed by using Ucinet 6.0 software.The results show that the urban tourism traffic accessibility and tourism economic linkages along the railway are both improved.But the increase extent has spatial differences.The improvement extent of the cities on the east side of the railway is greater than that of the cities on the west side of the railway.From the perspective of provinces and regions,the urban tourism traffic accessibility level of the cities with a better tourism economic base has been improved more significantly.In the future,how to realize the coordinated development of regional tourism industry and avoid neglecting the marginal tourist cities will be the focus.The Lanzhou Xinjiang corridor should give full play to Urumqi and Lanzhou as the core cities.At the same time,Jiuquan as the sub core city should exert itself as an agglomeration and diffusion center.The cities like Jiayuguan,Zhangye and Xining as the important tourist destinations should also act as the transferring and forwarding points to mobilize the tourism development in the marginal cities such as Turpan,Haidong and Kumul in order to build the so called “tourism+high speed railway” Silk Road Golden Route in northwestern China.The conclusion can provide theoretical basis and decision making reference for the development of high speed railway tourism in northwest China.
