| Mountain city is rich in tourism resources. Its scenic spatial structure is layered,clustering etc. How to optimize the spatial structure of the scenic mountain city in order to improve the quality of tourist travel experience, stimulating the growth of green GDP,which is a key to mountain city’s tourism planning.Currently, many researches are from the perspective of mountain tourism resources to analyze the particularity of development, classification and evaluation, or study the tourism resources spatial structure of specific scenic spots such as Qinling Mountain of Shanxi province, Longmen mountain region etc, while they are lack of researching the scenic spatial structure from the mountain city. Chongqing is a typical mountain city. The paper takes Chongqing as an example, comparing to other plain cities on the basic of "Point- Axis" theory, "mountain city" and other theories, and uses fractal dimension and GIS spatial analysis tool to study general and fractal characteristics of mountain city’s scenic spatial structure. Moreover, the paper uses expert investigation and fuzzy evaluation method to build an evaluation system of mountain city scenic spatial structure,and puts forward some suggestions.①Compare to plain city, mountain city is obviously fractal, and the sharper mountain is, the larger fractal dimension of mountain city scenic spatial structure is,then takes Chongqing urban scenic spatial structure as an example to verify it.②Combined with existing researches, the paper analyzes some general features of the mountain city’s scenic spatial structure: The mountain city’s tourism resources are richer; its tourism traffic is more complicate and three-dimensional; it has various kinds of traveling routes.Moreover, the paper points out optimizing structure modes of mountain city scenic.③The paper uses Delphi method and fuzzy analytic hierarchy process to construct an evaluation system of mountain city scenic spatial structure. The system consists of 4layers, including 3 first level indicators, 6 second level indexes and 14 third levelindexes. The study found that the most important in the first level indicators is scenic distribution, the second is scenic facilities distribution, and the last is scenic space connection; mountain scenic distribution, tourist service facilities and tourist connection of different scenic are important in second level indexes. The mountain tourism resource abundance, the accommodation service facilities and tourist concentration have higher weight in the third level indexes.④The paper uses the evaluation system to investigate Chongqing’s tourists in the perspective of visitor experience. The study found that most of tourists are satisfied with Chongqing tourism scenic spatial structure, while there are still some problems, such as high degree of concentration, long transportation time, and unreasonable facilities distribution.⑤According to the mountain city scenic spatial structure characteristics and survey,the paper proposes optimization strategies from tourism resources, tourist attractions facilities and the connection of tourist attractions.At last, on the basis of conclusions and innovative points, the paper points out shortage and the possible research directions of the study in future. |
