高铁对延边地区旅游可达性的影响分析

An Analysis of the Influence of High Speed on Tourism Accessibility in Yanbian Area

旅游历来与交通紧密相关。高速铁路的普及则直接改变区域内旅游资源的可达性,为改善区域内旅游资源的空间布局及协调区域旅游的发展带来极大影响。ArcGIS可视化平台分析区域交通可达性直观、有效,在此基础上采用费用加权距离法和成本加权栅格法,运用旅游等时圈指标体系,对比分析出高铁开通前后延边地区可达性空间格局的演变特征,结果表明:1.高铁具有明显的时空压缩效应,整体提高了延边地区的旅游通达力,为全域旅游创造了条件;2.高铁加剧了区域内旅游资源可达性的不平衡,线路端点及沿线站点城市获益最大;3.区域内各县市在1h-3h之间的可达性变化最为显著,当地旅游业将转变为一日游、自驾游及深度游模式。

Tourism has always been closely related to transportation.The popularization of high-speed railway will directly change the accessibility of tourism resources in the region,which has a great impact on improving the spatial layout of tourism resources and coordinating the development of regional tourism.ArcGIS is one of the most efficient tool on the analysis of regional transportation accessibility.This study used cost weighted distance method and costweighted grid method by establishing index system of same hour circle.It also gave a comparison on the accessibility of the Yanbian region before and after the evolution of high speed railway.The results showed that:1)the high-speed rail has obvious time compression effect,overall improved the accessibility of Yanbian area's tourism;2)the high-speed railway aggravates the imbalance in the accessibility of tourism resources within the region,which the destination of the route and the site cities along the route benefit the most;3)the most significant change in accessibility of each county and city within the region is between 1 hand 3 h,which will transform the local tourism into one-day,self-driving and in-depth tourism mode.
