交通可达性与旅游经济联系协调发展时空演变——基于成渝地区双城经济圈截面数据

The Spatial and Temporal Evolution of the Coordinated Development of Traffic Accessibility and Tourism Economic Linkages:Based on the Cross-sectional Data of Chengdu-Chongqing Economic Circle

以成渝地区双城经济圈为研究区域,选取2011年和2019年为时间断面,对高铁开通前后交通可达性和旅游经济联系强度进行测算和分析,结论表明:(1)交通可达性呈现出以中部城市群为核心,向外侧逐渐递减的圈层式空间格局,具有鲜明的空间分级结构及发展不平衡的特征;(2)旅游经济联系空间网络化趋势显著,从点轴形态演化为扇形网络化特征,具有多中心性和交通导向性;(3)区域内交通与旅游经济系统整体协调水平仍处于中等协调水平,耦合协调度层次存在明显的地域差异,高铁的开通缩小了这种差异;交通可达性与旅游经济联系耦合度有明显的空间自相关性,空间聚集效应发展趋势呈强化状态,但整体不平衡性依然存在。

Taking Chengdu-Chongqing economic circle as the research area,2011 and 2019 as the time sections were selected to measure and analyze the traffic accessibility and tourism economic connection intensity before and after the opening of the high-speed railway.The conclusion showed that the traffic accessibility presented a circle-type spatial pattern with the central urban agglomeration as the core and gradually decreasing outwards,with a distinct spatial hierarchical structure and unbalanced development;the spatial networking trend of tourism economic relations was remarkable,evolving from the point axis form to the fan-shaped network characteristics,with polycentricity and traffic orientation;the overall coordination level of the transportation and tourism economic system in the region is still in the medium coordination stage,and there are obvious regional differences in the coupling coordination level,which is narrowed by the opening of high-speed rail;the accessibility of transportation and the coupling degree of tourism economic linkage have obvious spatial self-correlation,and the development trend of spatial aggregation effect is strengthened,but the overall imbalance still exists.
