交通网络与城市群旅游地耦合协调演化研究

基于交通网络和城市群旅游地的双向视角,以长株潭城市群为典型案例地，构建城市群交通网络和旅游地的耦合协调演化的评价指标体系，利用综合评价法、耦合协调度模型等方法，分析二者耦合协调演化过程。结果表明：①长株潭城市群交通网络和旅游地发展水平呈协同上升态势，演化大致可以划分为两个阶段，发展水平差异呈倒“U”型下降态势。②城市群交通网络和旅游地发展空间格局均呈现出以长沙为热点区，其他城市为外围受辐射冷点区的空间格局特征，但内部空间格局的非均衡性仍然较大。③长株潭城市群交通网络和旅游地发展水平耦合协调度由“失调”阶段逐渐向“转型过渡”和“优化协调”阶段演变，长沙市一直处于高耦合协调的单极态势，中高耦合协调度地区趋于集聚于城市群东部旅游集散地，低耦合协调度区位指向远离旅游集散地的城市群西部地区。

Study on the evolvement of coupling coordination between transportation network and tourism resort of urban agglomeration

Based on the two-way perspective of transportation network and urban agglomerations, the Chang-Zhu-Tan urban agglomeration is used as a typical case to construct an evaluation index system for the coordinated and coordinated evolution of urban agglomeration transportation networks and tourist sites, using comprehensive evaluation methods, coupling coordination degrees models, etc. The method analyzes the coupling and coordination evolution process of the two. The results show that: ①The development level of the transportation network and tourism destinations of the Chang-Zhu-Tan urban agglomeration is in a synergistic upward trend. The evolution can be roughly divided into two stages, and the difference in development level is in a downward trend of “U” type.②The spatial pattern of urban agglomeration transportation network and tourism development shows that Changsha is a hot spot, while other cities are characterized by the spatial pattern of the outer cold-radiation area, but the imbalance of internal spatial pattern is still large.③The coupling degree of the transportation network and tourism development level of the Chang-Zhu-Tan urban agglomeration has evolved from the “disordered” stage to the “transition transition” and “optimization coordination” stages. Changsha has been in a unipolar situation with high coupling and coordination. The medium-high coupling coordination area tends to concentrate in the eastern tourism distribution center of the urban agglomeration, and the low coupling coordination degree points to the western part of the urban agglomeration away from the tourism distribution center.
