Abstract:

The impact of transportation on accessibility of cross-border scenic area is an important aspect of research on cross-border tourism region. In this article, we focus on cross-border tourism region in Dabieshan Mountain. Through constructing regional internal accessibility, regional external accessibility, analyzing quantitative accessibility of scenic area of cross-border tourism region in Dabieshan Mountain with GIS software, and generating spatial structure schematic drawing, we arrive some conclusions that: 1) Highway plays a crucial role in improving internal global accessibility, but the impacts of ordinary railway and high speed railway on accessibility are not obvious. 2) As far as single transportation way is concerned, the impacts of high speed railway, ordinary railway and highway on improving internal local accessibility are limited. This is due to the characteristics of shielding of them and the limited quantity of entrance and exit of railway station and highway, which also make them not to become universal transportation so far. 3) By measuring boundary effect, we find that the shielding effect of administrative boundaries on low-rank transportation infrastructure is better than that on high-rank traffic facilities. 4) The impact of universality transportation way on external global accessibility is weak, and the effect of ordinary railway and highway on improving global accessibility is greater than the effect of high speed railway. Combined with data from the survey, this article holds that: although highway is not universal traffic way in the case area at present, regional external accessibility of the whole cross-border tourism region in Dabieshan Mountain will be improved based on the continuous construction of highway network, and highway also will gradually become a ubiquitous transportation way. 5) The impact of high-grade traffic facilities are mainly embodied in regional external accessibility. Taking typical cross-border scenic area—Tiantangzhai as an example, by measuring border effect of cross-border scenic area based on construction of time accessibility non-line coefficient, and drawing spatial differentiation figure of accessibility of scenic area, this article finds out: distribution structure of administrative areas on both sides of cross-border scenic area present significant symmetric pattern——with provincial boundaries for axis, cross-border scenic area for the symmetric point, from county administrative region to prefectural-level city, to the capital city, and the higher administration rank, the smaller time accessibility non-line coefficient, the stronger the impact of high-grade traffic facilities. It shows that the shielding effect of boundary on transportation infrastructure exists in cross-border scenic area, and action effect follows the distance attenuation law, which presents significant administrative areas symmetrical pattern. Accessibility of scenic area can reveal border effect of boundary on transportation infrastructure, prove accessibility is a kind of effective method of measuring border effect, and provide a new perspective for the study on cross-border tourism region integration. In order to break the shielding effect of boundary on transportation infrastructure, firstly we should promote the construction integration of cross-border low-rank transportation infrastructure, including state roads, provincial roads, county roads, which make the provincial fringe area traffic facilities be shared, and then improve accessibility of scenic area, transfer shielding effect into intermediary effect in certain extent. Therefore, it is necessary to coordinate traffic infrastructure construction planning and investment distribution relationship about transportation infrastructure in cross-border tourism region. The integration and share of the transportation infrastructure construction must be a common key strategic of cross-border tourism region to implement.
