THE IMPACT OF KEY TRANSPORT FACILITY ON REGIONAL TOURISM SPATIAL STRUCTURE——A CASE STUDY OF THE TRANS-STRAIT PASSAGE IN THE BOHAI STRAIT
定量分析了渤海海峡跨海通道对环渤海地区公路和铁路网络可达性的影响，发现大连和烟台成为新交通枢纽和旅游增长极，并改变了区域旅游空间结构。
Key transport facility is not only an important basis of economic development,but sustainable valuable resources of tourism development.In this paper,we focus on the Trans-strait Passage in the Bohai Strait and aim to analyse quantitatively changes in highway network accessibility in Bohai Rim Region,caused by the Trans-strait Passage through network accessibility index,three-steps depth value and distance accessibility index.Choosing point betweenness centrality and line betweenness centrality as the indicators,we analysed quantitatively the influence of the Trans-strait Passage in railway network accessibility in Bohai Rim Region.Based on comprehensive consideration of the changes of transport accessibility,tourism resources,tourist market,tourist line and etc,we found that: Dalian and Yantai become new traffic hubs and tourism growth poles in Bohai Rim Region;Trans-strait Passage tourism development axis will be more obvious;this tourism development axis radiates Shandong Peninsula and Liaodong Peninsula,form two tourism radiation belts—Shandong Mountain-Sage and Qilu culture tourism radiation belt and Central and Southern of Liaoning tourism radiation belt;under the influence of the Trans-strait Passage,tourism spatial structure in Bohai Rim Region with the former Two growth poles,Four development axises,Three tourism plates,Five regions evolved into Two growth poles,Two development axises,Three tourism plates,Six regions,Two radiatings.
