| The individual travel market in China is experiencing a rapid development stage.The sampling survey in 2011 showed that 82.5% of urban residents in China attend the individual travel, of which its rate substantially beyond the team travel, become the main form of tourism development. The tourism distribution center as a specifically for individual clients services arises at the historic moment.Tourism hub launch circuit for use of public transport travel tourists have important guiding role,guiding the flow of tourists in the region, and Travel line is important reference for travelers. Many researchers have recognized the importance of travel line, however few of them investigate spatial flow from the point of individual travelers, but the travel line provided by travel agencies. As individual clients in China market development in Yangtze river delta is the most perfect area, tourism hub overall development level is higher than other area, is an important distributing center of tourist flow in our country, therefore this article focus on spatially analyzing the travel line and exploring the spatial mode for people at this area, basing on the data of tourist distributing center at the Yangtze River Delta Region, by the method of statistical analysis and social network analysis, in order to make clear that tourist destination is playing what kinds of role at the Yangtze River Delta Region.This article has 3 parts.Part I is the basis of the research background, including the first and the second chapter. Part I provides background, theoretical and practical significance. It tells where all the data come from and research methods and draws out the technical travel line diagram. Then It introduces tourist distributing centers and spatial mode travel line domestically and abroad. It also tells tourist flow theory, distance-decay theory and hierarchy of cities theory, which provides the theoretical basis for the whole article.Part II is the system analysis of the tourist center line, including the third, the fourth and the fifth chapter, which is the main content of this article, mainly from three aspects in this paper.Firstly, it summed up the features of the Yangtze River Delta cities tourist center.The Yangtze River Delta 16 cities tourist center development level is different, and its management pattern mainly the government-leading, market-oriented operation,operation condition overall is good, the site selection model mainly stadiums and transportation hub, features in operation.Secondly, this paper analyze the tourist center line of the Yangtze River Delta.The Yangtze River Delta has its unique characteristics:short travel line is the main line;travel line combination is too single; the attraction of tourist spots affect the design of line pattern; traffic network effect is obvious.Based on the statistical analysis of tourist center line pattern of the Yangtze River Delta, finding that single destination is the main line mode and total round trip is another mode at this area. Then it works out the frequency of destination and divides 16 cities to 3 hierarchies: main destination,secondary destination and third-level destination. Through the spatial behavior pattern and influences: The central line appears hierarchization; distance-decay theory is not that apparently. The spatial mode of central line is influenced by many aspects, mainly focus on two: tourist factor and destination factor.Finally, based on tourist center line, this paper provide the regional tourism space network structure of the Yangtze River Delta. It draws out the travel line network mode by using social network analysis. It connects 16 cities at this area by the method and works out the travel line density is 0.2, which means the connection among these cities is not that close. Then by using central index and the spatial analysis, it comes to the conclusion that Shanghai, Hangzhou, and Nanjing are the central cities at the Yangtze River Delta Region and their agglomeration, diffusion and transfer is the best;Jiangsu, Wuxi and Jiaxing are the main agglomerate cities and they are secondary central cities; Yangzhou, Changzhou, Huzhou and Ningbo are the important traveling cities; Zhenjiang, Taizhou, Shaoxing, Taizhou and Zhoushan are the normal node cities and marginal cities at this region because of the low agglomeration, diffusion and transfer. Nantong is an isolated city, which has the weakest connection with other cities.Part III is the conclusion part, including chapter six. It points out the main idea of this article and inadequacy needed to be improved. |
