摘要
针对基于路网的景点可达性不能单独体现铁路对可达性提升的效果,为更好研究不断优化的铁路网对区域内旅游业发展的促进作用,提出以2007、2014和2017年3个时间断面甘肃省的旅游热点和铁路网为研究对象,运用GIS空间分析工具和地学统计方法,对景点的空间分布特征及铁路网可达性的时空演化规律进行研究,并预测2022年旅游热点的铁路网可达性。结果表明,可达性呈现以兰州为中心向外围区域递减的"核心-外围"模式,铁路建设大幅度缩短了各旅游热点的可达时间,能够为"一带一路"倡议下甘肃省的旅游业发展服务。
The accessibility of scenic spots based on the road and railway network cannot reflect the effect of railways on the accessibility improvement alone.So as to better study the role of optimized railway network in promoting the development of regional tourism,based on the railway network and tourism attractions in 2007,2014 and 2017,choosing spatial analysis tools of GIS and geoscience statistics methods as ways,the spatial distribution characteristics of tourism attractions and the spatialtemporal evolution of the railway network accessibility in Gansu province are studied.At the same time,the tourism hot spots accessibility in 2022 is predicted.The results show that tourism hot spots reach the"core periphery"pattern with Lanzhou as the center and the periphery area decreasing.Railway construction has greatly shorten the accessibility time among tourism attractions along the railway,which can provide services to develop"the Belt and Road"initiative of tourism in Gansu province.
