环长株潭城市群陆路交通可达性与旅游流集散耦合协调发展分析

Analysis on theCoupling Coordinated Development of Land Transportation Accessibility and Tourism Flow Distribution in the Urbanagglomeration around Changzhou-Zhuzhou-Xiangtan

旅游流一直是旅游地理学关注的核心问题之一。以环长株潭城市群为研究对象,应用GIS空间分析法和耦合协调度模型,分析了2005-2017年环长株潭城市群陆路交通可达性与旅游流集散协调发展状况及其演变特征。研究表明:(1)环长株潭城市群交通可达性不断提高,不同交通方式可达性均呈现出东高西低的空间特征,公路可达性呈“核心-边缘”结构,普铁与高铁无明显结构特征。(2)基于公路、普铁、高铁的旅游流经济联系总量下,长沙市始终处于旅游流联系的核心地位,对其他城市产生辐射和影响。岳阳、衡阳为旅游流联系的次核心地区,对其他城市的旅游流吸引力较大,旅游流较为集聚。(3)环长株潭城市群交通可达性与旅游流集聚程度耦合协调度较高。公路与旅游流集散耦合协调度整体高于普铁、高铁与旅游流集散的耦合协调度。

Tourism flow has always been one of the core issues of tourism geography. In this paper,the urban agglomeration around changsha-zhuzhou-xiangtan is taken as the research object, and GIS spatial analysis method and coupling coordination degree model are applied to analyze the coordinated development status and evolution characteristics of land traffic accessibility and tourism flow joint distribution of the urban agglomeration around changsha-zhuzhou-xiangtan from 2005 to 2017. Research shows that:(1) the ring the traffic accessibility of changsha-zhuzhou-xiangtan urban agglomeration, different transportation accessibility spatial pattern in different degree, presents the east west high low,accessibility of highway is“core - edge”structure,the core area and decreases,PuTie no obvious structural features with high-speed,high accessibility area expands unceasingly.(2) the city based on highways, urban agglomerations PuTie, high iron tourist flow,total economic ties at the core position of tourism flow connection of changsha, radiation and influence on other cities,yueyang,hengyang contacts for tourist flow of core area, attractive to other urban tourism flow is larger, more agglomeration tourism flow.(3) the traffic accessibility of changsha-zhuzhou-xiangtan urban agglomeration and the degree of tourist flow agglomeration coupling coordination degree is higher, the period of study, different modes of transport and tourism flow distribution of the coupling coordination degree show varying degrees of rise,including roads and tourist flow distributing coupling coordination degree of the whole higher than PuTie, high-speed and tourist flow distribution of the coupled coordination degree.
