中文摘要：

跨界旅游区是中国重要的潜在旅游目的地，而可达性大小是制约其旅游一体化发展的主要因素之一。通过构建景区区内可达性、景区区外可达性两类指标，运用GIS软件定量分析大别山跨界旅游区景区可达性，生成空间格局示意图，发现：（1）国道、省道、县道构成的普适性交通网络的完善程度对景区区内可达性起着决定性的影响作用，而高速公路、普通铁路、高速铁路可以有效提高景区区内可达性；（2）普适性交通网络对景区区外可达性的影响力最弱，高速公路在改善景区区外可达性方面起到关键性作用，普通铁路的影响力不及高速公路，高速铁路仅对停靠站附近的景区有所影响。最后构建了景区、交通、旅游集散地耦合发展模式。

英文摘要：

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 lbeen 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, ki;nds of indexes were built, including scenic area intra-regional accessibility and scenic area extraregial 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 irtra-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 Ii;mited 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 nationai, 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 rai
