摘要
旅游交通可达性分析能够为区域旅游交通规划提供理论依据,而高速铁路的开通将直接改变区域旅游交通可达性格局.本文采用加权平均旅行时间作为节点城市旅游交通可达性的评价指标,利用Arc GIS可视化平台分析旅游交通可达性空间格局,获取高铁开通前后云南省旅游交通可达性的演变特征.在此基础上,对公路、铁路、航空和高铁的权重进行灵敏度分析,辨识出旅游交通可达性对各种交通方式权重的敏感度.结果表明:高铁途经的各城市客源地到达云南的旅游交通可达性水平均有大幅提升,旅游交通可达性的时空收敛效应显著,省外城市到达昆明的旅游交通可达性对铁路权重的敏感度较大;高铁开通之后,云南省旅游交通可达性格局总体呈现以昆明为中心向外围区域递减的'核心—外围'模式;高铁开通前后,云南省内旅游交通可达性的变化幅度较小,地区间的总体差异也不断缩小,省内高铁途经城市的旅游交通可达性对高铁权重的敏感度较大.
Tourist transport accessibility analysis can provide theoretical basis for regional tourism transport planning. The operating of the high- speed railway will directly change the accessibility pattern of the regional tourist transport. In this paper, the weighted average travel time is used as evaluating index in node urban transport accessibility, and the Arc GIS visualization platform is used to analyze the spatial pattern of tourism transport accessibility. Then the evolution characteristics of tourism transport accessibility in Yunnan Province are obtained before and after the high-speed railway operating. On this basis, the sensitivity analysis of the weight of highway, railway, aviation and high- speed railway, to identify the sensitivity of tourism traffic accessibility to the weight of all kinds of traffic mode. The conclusions show that： The accessibility level of the high- speed railway travel to Yunnan Province is greatly improved, and the spacetime convergence effect of the tourism transport accessibility is obvious, outside the city to Kunming tourism traffic accessibility of railway weight greater sensitivity; After the operating of high- speed rail of Yunnan Province, the overall pattern of tourism transport accessibility to Kunming as the center to the periphery of the periphery of the ＂core- periphery＂ model; Before and after the high- speed railway operating, the variations of tourism transport accessibility is small in Yunnan Province, but overall differences between regions is narrowing, high speed railway passing through the city of tourism traffic on the high speed railway weight sensitivity.
