Abstract:

Crossborder tourism area is important potential tourism destination in China， while the size of accessibility is one of the main restrictive factors of integrated development of tourism. Accessibility is an efficient and comprehensive index for transport network evaluation. The traffic impact on accessibility has been the hotspot research in the transportation geography. Abroad researchers take more work on accessibility theory which is relatively mature， and empirical research is also more indepth. From the perspective of selected cases， domestic researchers mostly concentrate in accessible areas， less involve crossborder tourism areas. Thus，we focus on the accessibility of crossborder tourism area. In this study， two kinds of indexes were built， including scenic area intraregional accessibility and scenic area extraregional accessibility. Taking Dabie Mountain crossborder tourism scenic area for example， Dabie Mountain crossborder tourism scenic area was analyzed and the spatial pattern diagram was generated by using GIS software quantitative analysis method. The results show that， the effect of single transportation on regional intraregional accessibility was limited， but  the effect of entrance and exit of the expressway and railway station nearby tourism scenic region was significant. Due to the characteristics of sealing and the limited quantity of entrance and exit of the expressway and railway station， the expressway， common railway， highspeed railway had not become universality transportation. Degree perfection of universality transport network played a decisive influence on the scenic area intraregional accessibility， which included the national， provincial and county roads. Then the expressway， common railway， highspeed railway could effectively improve the intraregional accessibility. Universality transport network had the weakest influence on the scenic extraregional accessibility. The expressway played a key role in improving scenic area extraregional accessibility. And the common railway had less influence，compared with expressway. The expressway only had an impact on the scenic spots near the railway station. Market mechanism and government guidance need to be carried out simultaneously to succeed in developing the scenic area， transportation and tourism center. The government agency should set up crossborder coordination， draw up crossborder area， transportation， distribution center coupling development plan， in order to weaken the geographic boundaries and the rigid constraints of traditional administrative boundaries. Especially in the early coupling，crossborder cooperating agency should provide more support from financial， policy and other aspects， harmonize both sides of the border relevant departments， such as the transport sector， tourism management department， department of transportation and other departments. We also need to create favorable external hardware environment for coupling functions of the scenic area， transportation， tourism centers. In addition， the coupling body of the scenic area， transportation， tourism centers should take the road of marketoriented operation， selfmanagement， selffinancing， in order to enhance the ability of adapting to market competition. Finally， this paper constructed the area， transport， tourism center hub coupling development mode， in the hope of understanding the accessibility scenic area spatial pattern in crossborder tourism， revealing its inherent laws， and trying to provide theoretical inspiration and practical guidance for building tourism centers， transportation infrastructure and the development of crossborder.
