Study On The Network Structure Of Domestic Self Service Tourist Flow In Qinghai From2012 To 2015

Recently, domestic Tourism has become the main part of Chinese tourism, and self-tourism as a new way to develop tourism, which is of great benefit to upgrade Qinghai tourism consumption structure. The study on the network structure of self service tourist flow in Qinghai can measure the importance of tourism nodes in the network structure of Qinghai domestic self service tourist flow; can distinguish whether a tourism destination is in the core or in the peripheral of the network; can discover the link degree of tourism destinations, can find out the problems of developing self-service tour in Qinghai and proposed corresponding suggestions.Based on mining the tourism strategy released on the internet, using the method of social network analysis, this thesis made a study on the network structure of self service tourist flow in Qinghai from 2012 to 2015 through 3 aspects which including visual analysis, node structure analysis and the whole network structure.(1) the most popular tourism nodes in Qinghai from 2012 to 2015 are: Xining,Erlangjian, Caka Salt Lake, Zhuoer Mountain, Ta’er Lamasery, the Gold and Silver River Beach- Atomic City, Heimahe river. And the less popular tourism nodes are Jiegu town of Yushu Prefecture, Nianbaoyuze, Hoh Xil. Caka Salt Lake, Ta’er Lamasery and the Bird Island are the main gathering points. Erlangjian, Zhuoer Mountain and the Gold and Silver River Beach- Atomic City are the main radiant points. Xining, Heimahe river and kampula are both gathering points and radiant points.(2)The tourism nodes which have the highest degree centrality are Xining and Erlangjian. The degree centrality of tourism nodes is obvious positively correlated to the level of tourism nodes. Xining, Erlangjian, Zhuoershan and Caka Salt Lake, which are independence, have good accessibility and can control other tourism attractions strongly, have highest medium centrality and approach centrality. Xining, Caka Salt Lake, Erlangjian, Zhuoer Mountain, Ta’er Lamasery and the Gold and Silver River Beach- Atomic City have obvious location advantage and stronger competitive power among Qinghai tourism nodes.(3) The density of the network structure of Qinghai’s self service tourist flow is at the middle level, so is the link, central tendency of tourism nodes and theirdependence on other nodes. The subgroup comprising of Xining, Ta’er Lamasery and Menyuan has obvious radiation effect on the subgroup comprising of Riyue Mountain-Daotanghe river, Jiegu Town and the subgroup comprising of Caka Salt Lake and Erlangjian; but has less radiation effect on the subgroup comprising of Huangyuan Vally and Tanglha Mountain of which its radiation effect should be enhanced. There are 16 core members in the network including Xining, Ta’er Lamasery, Erlangjian, Caka Salt Lake and Zhuoer Mountain. The other members of the network are in the peripheral area. The core nodes are linked closely to each other,but not the core nodes and the peripheral nodes, nor the link among the peripheral nodes. The radiation effect of the core nodes to the peripheral nodes is not strong.
