Analysis And Optimizing On The Spatial Structure Of National A-Grade Tourist Attractions Of Central China Delta Economic Region

The regional tourism structure spatial structure refers to the compredhensive relations of tourism factor’s spreading and character in a certain tourist. It is the projection of regional tour acivities on the regional places. And scenic spots is an important material foundation, the economic development of regional tourism scenic area spatial structure optimization or not has an important influence on the further development of regional tourism industry. The three area of Hunan Jiangxi Hubei province make full use of the rich tourism resources, seize the opportunity of rise of central China, established in the triangle economic circle, make tourism industry gets rapid development. Delta economic circle in the study, therefore, national a-class tourist scenic spot, the triangle region in the tourism resources development and integration, the layout and planning of tourism scenic spots has the important significance.Paper first for scenic spots, especially tourism spatial structure research were briefly reviewed, and on this basis, determine the research framework of the thesis; And then, according to the characteristics of tourism scenic area and the development of the tourism industry in Central China Delta Economic Region, on the basis of GIS, the paper analyzes the status of the spatial structure of tourist attractions, mainly uses the coefficient of variation, The geographic concentration index, the Gini coefficient and the nuclear density analysis, and also analyzes spatial distribution of scenic spots, density, and regional differences.The results show that River delta economic circle in the national a-class tourist scenic area overall distribution is not balanced, the traveling scenic area overall trend clustering on the space distribution state. River delta economic circle in the national a-class tourist scenic spot of high degree of centralization, only Enshi Huanggang Wuhan Changsha Gian Xianning Xiangyang, which is, Yichun Ganzhou10cities as the total number of national a-class tourist scenic spot has231, accounts for the entire river delta national a-class tourist scenic spot of almost50%, the distribution of Jingmen Tianmen Xiantao Qianjiang less. River delta economic circle in the national a-class tourist scenic spot distribution form several core and scattered have no scale. On the basis of the tourism scenic area spatial structure in the central China delta economic region, according to the spatial distribution characteristics of tourism scenic spot, traffic conditions and so on, put forward the optimum path of the space structure of tourism scenic spots, and put forward the optimization of safeguard measures, in order to promote healthy sustainable development of tourism in the central China delta economic region.
