渝鄂边界区县域交通可达性与旅游经济联系空间耦合分析

Spatial Coupling Analysis on the County Transportation Accessibility and Tourism Economic Connection in Chongqing-Hubei Border Areas

省域边界区交通发展往往薄弱,限制了交通发展的旅游效应。以渝鄂边界区为研究区域,选取2009年和2019年为时间截面,利用最短时间距离和引力模型,对渝鄂边界区各县市交通可达性与旅游经济联系进行耦合分析。结果表明:1)渝鄂边界区各县市之间交通可达性得到提升,且西部交通可达性优于东部,但区域之间交通可达性的绝对差距仍在扩大;2)区域旅游经济联系强度呈现西高东低格局,与交通可达性呈正比;3)旅游经济联系总量空间差异大,空间极化特征显著且呈现出“核心—边缘”空间格局;4)交通可达性与旅游经济联系耦合协调水平较低,交通系统和旅游经济系统均处于滞后状态,“高交通可达性—低旅游经济联系”(H-L)为研究区主体耦合模式,整体反映了交通可达性与旅游经济联系不协调的发展态势。

The transportation development in provincial border areas is often weak,which limits the tourism effect of transportation development.Taking the border areas between Chongqing and Hubei as the study areas,2009 and 2019 as the time interface,using the shortest time distance and gravity model,this paper makes a coupling analysis on the transportation accessibility and the tourism economic connection at county-level in Chongqing-Hubei border areas.The results show that:1)The transportation accessibility between counties and cities in Chongqing-Hubei border areas has been improved,and the transportation accessibility in the western areas is better than that in the eastern areas,but the absolute gap in accessibility between areas is still expanding.2)The intensity of tourism economic connection shows a pattern of high in the west and low in the east,which is proportional to transportation accessibility.3)The total amount of tourism economic connection has a large spatial difference,and the spatial polarization characteristics are significant,showing a"core-edge"spatial pattern.4)The coupling coordination level of transportation accessibility and tourism economic connection is low,and both the transportation system and tourism economy system are lagging behind."High transportation accessibility-low tourism economic connection"(H-L)is the main coupling mode of the study areas,which reflects the uncoordinated development trend of transportation accessibility and tourism economic connection.
