中文摘要：

交通方式对跨界旅游区景区可达性影响是跨界旅游区研究的重要方面。以大别山跨界旅游区为例,通过测度不同交通方式影响下的景区可达性,结果显示高速铁路、普通铁路、高速公路、普适性交通等交通方式对大别山跨界旅游区整体和局部地区的影响力不同。通过测度边界效应发现,行政边界对低等级交通基础设施的屏蔽效应强于高等级交通设施。以典型的跨界景区——天堂寨为案例,构建＂时间可达性非直线系数＂指标测度跨界景区的边界效应,发现行政边界对交通基础设施的屏蔽效应存在于跨界景区之间,其作用效果遵循距离衰减规律,呈现显著的行政区域对称格局。运用可达性方法为跨界旅游区边界效应的测度提供了一个新的视角和有效的方法。

英文摘要：

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 high-way,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 cros
