An Analysis for Market Area of Chinese National Park Based on Railway Corridor

This paper introduces concept of market area of national park and its analytic model, i.e. spatial interaction model between national parks and cities, and developed a technique to calculate the solution of the shortest distance between national parks and a city. Then, we get the market area of national parks of China after identifying and dividing the market area of Chinese national parks with GIS environment in technology. The following conclusion were reached: 1. In China, ten national parks that have the largest market area in order are Badaling in Beijing, Westlake in Hangzhou, Taihu lake, Lishan in Lingtong, Chengde, East Lake in Wuhan, Taishan Mountain, Songshan Mountain and Zhongshan Mountain in Nanjing, Beidaihe in Qinhuangdao. 2. The resource conditions of every national park in China have great influence on the size of its market area such as Badaling and West Lake in Hangzhou. 3. Because of dense population tourism visitor resource index is much higher in eastern of China. Therefore, there is promising commercial prosperities in tourism in the eastern region. 4. The size of market area of every national park is closely related with special location of city groups where they are locateed. 5. It's hard to develop efficient tourism in west China as it is dependent on current railway transportation. So the key to promote the development of tourism in the west region is to speed up the development of aviation industry; or develop more airlines like Yunnan.
