Research on spatial coupling of traffic accessibility and tourism flow in Xinjiang
Under the construction of rapid transportation,Xinjiang,a Northwest China,en-dowed with its unique resources has developed rapidly in the tourism industry.Analyzing the structure of the tourism flow network is of great significance for the subsequent improvement of the regional transportation network and identifying and evaluating the location advantages and development potential of scenic spots.Taking Xinjiang 4A and 5A high-grade scenic spots as the research objects,with the help of GIS spatial analysis technology,the raster cost distance method and network analysis method were comprehensively used to calculate the overall aver-age travel time in Xinjiang accurately,and the time circle of scenic spots was visualized.At the same time,the social network analysis module of Gephi and Ucinet software was used to de-scribe the spatial layout of the tourism flow network,and the coupling coordination model was used to explore its coupling association with accessibility.The results showed that:(l)The spa-tial difference in accessibility of scenic spots is significant and the level is not high,and the over-all view is strong in northern Xinjiang and weak in southern Xinjiang,which coincides with the distribution of irregular"well"shaped high-grade transportation network,and has obvious traffic directionality.(2)The isochronous circles are represented by an irregular annular structure cen-tered on Urumqi City,exhibiting a pattern of distance decay.(3)The tourism flow network of 4A and 5A scenic spots in Xinjiang is generally large,but the network accessibility is good,the cohe-sion is relatively strong,and the overall performance is core-edge characteristics.(4)The core position of 5A-level scenic spots is prominent,with a strong radiation driving effect,undertaking the main agglomeration and diffusion functions,and forming a tour mode of"one 5A core scenic spot+several 4A-level scenic spots".(5)The coupling level of traffic accessibility and tourism flow in Xinjiang is generally low,and most scenic spots in the tourism flow network are within the 6h isochronous circle.Infrastructure construction such as transportation around most 5A-lev-el scenic spots in Xinjiang should be strengthened to further improve the level of actual accessi-bility;It is common for 4A-level scenic spots to lag behind the actual accessibility level of tour-ism circulation.
