Abstract:

The process of emerging and developing in Chinese Excellent Tourism City is the process of macroscopic management and organization of tourism cities and its infrastructure spatial effect is also going hand in hand with the process of China's modern tourism development and China's city construction. In the past 20 years, theoretical exploration and practice construction have made great progress though there are also some problems in the spatial distribution and its spatial effect of the transport accessibility. In this article, regional differences of the spatial distribution and its transport accessibility in 1 hour, 2 hours, 3 hours of the Chinese Excellent Tourism Cities were compared with the ArcGIS spatial orientation and spatial analysis technology. And the results showed that: the regional differences of transport accessibility of Chinese Excellent Tourism Cities have a high degree of consistency to the nationwide spatial distribution differences. Firstly, there are a large number of Chinese Excellent Tourism Cities in the eastern of China while a little in the western, the number of Chinese Excellent Tourism Cities in different provinces is quite different, and the regional difference in different prefecture level cities can be subdivided into 3 kinds of region. Secondly, there are also a great many of differences in the spatial distribution of transport accessibility of the Chinese Excellent Tourism Cities all over the whole country, and the regional economic which based on the spatial distribution also has the same character. From the Heihe City in Heilongjiang Province to the Dali City in Yunnan Province, there can be a line of demarcation of spatial distribution for 3 hours accessed area between the eastern of China and the western. In the southeast coastal area, the Huanghuai area and the JiangHuai River Basin of China,such as Henan Province, Jiangsu Province, Zhejiang Province, Liaoning Province, Hainan Province ,the 1 hour accessed area can be a big advantage for the development of the tourism. While, in the southwestern and northwestern of China, such as Qinghai Province, Xizang Autonomous Region, Yunnan Province and Inner Mongolia, the 3 hours accessed area may be the disadvantage in opposite, just because of the interaction of many factors of regional difference, such as the topography condition, urban terrain settlement distribution, the construction of urban transportation infrastructure facilities and so on. Thirdly, the law of distance decay of tourist market and tourism development potential appear vividly around 1 hour,2 hours, 3 hours accessed area of 339 Chinese Excellent Tourism Cities. And the development and construction of the Chinese excellent tourism city should be further improved.
