Mobility not only breaks through the restriction of traditional "place space" and "regional difference",but also becomes an important form of connotation interpretation of "flow space" and "regional relationship",and becomes the dominant regional spatial logic. On the basis of the fine data of the expressway network toll collection,this paper analyzes the accessibility of the tourist scenic spots,explores the spatial relationship between the expressway flow and the scenic spot tourism flow applying the coupling correlation model and puts forward the coupling path of the coordinated development of the expressway and the scenic spot. The results show that: 1) From 2011 to 2019,the intra-provincial accessibility of the scenic spots was gradually improved in Jiangsu Province,and the best places of accessibility were mainly distributed in Suzhou and Wuxi,where the shortest drive is less than half an hour. Better places of accessibility were distributed in Zhenjiang,Changzhou and Nanjing where were located in G42 along the Yangtze River. 2) Based on the coupling relationship between freeway flow and tourism flow in scenic spots,their spatial relationship successively presents the characteristics of decentralized association and agglomeration association of inner city. The agglomeration association of inner city becomes more relevant,more dense,which is mainly attributable to the continuous improvement of the highway network and the driving effect of the surrounding scenic areas.
