Abstract: The scale of tourism output is closely related to the radiation effect of the tourism industry.With the integration of the ranksize theory model, the Gini coefficient (G), coefficient of dispersion (CV), Hector fender index (Hn), and the first degree (S), as well as quantitative analysis, this paper analyzes the distribution of tourism output size and the size difference variation in the counties of Wuling Mountain Area from 2010 to 2015. The tourism scale index is used to evaluate the quality of tourism production scale. And according to the standards of the size of the scale (high and low) and quality (excellent, fine, common and bad), eight levels are concluded and based on this basis, the method of social network analysis is used in the analysis of space structure and the size of the network node of the area tourism output. With the help of Pajek and GIS, the visual representation of the evolution shows itself and there are three main conclusions: ⑴The tourism output scale of Wuling Mountain Area in Hunan Province is higher than that of tourism, and the tourism income scale is higher than that of tourism. Meanwhile, the size of the tourism population and tourism income scale are nonsynchronous in the distribution of the trend of the existence,The absolute difference in the scale of tourism output at the current stage is higher in tourism revenue and tourism, but the relative degree of difference is gradually weakened; ⑵Tourism output quality grade Ⅰ type accounted for only 1/4, while Ⅱ type, Ⅲ type and Ⅳ type are vacant. Besides the lowscale four types accounted for 3/4 of the total number. The size of the county and township tourism output scale quality needs to be improved; ⑶Center degree, structural hole and other indicators of the change reflect that with the increase of the tourism flow and diffusion effect, the degree of importance in traditional tourism counties decreases. The impact of emerging tourism counties are strengthening. All of these effects are favorable to narrow down the balance of tourism output in Wuling Mountain Area;⑷The tourism development of largescale tourism is becoming more and more important, which can balance the tourism output scale in this area and achieve the effectiveness of tourism poverty alleviation to the most degree
