| The tourism industry has become a driving engine for the optimization and upgrading of the tertiary industry.Under the industrial economic development mode dominated by "green environmental protection",tourism industry is a strategic emerging industry in the development of the tertiary industry.At present,most of the cities dominated by industry pay too much attention to the development of secondary industry and neglect the relationship between industrial development and ecological environment protection.For example,cities with developed industries produce a large amount of industrial waste gas and waste residue due to their high energy consumption and high emission,resulting in serious environmental pollution,destruction of the ecological environment and imbalance of industrial and economic structure.Therefore,it is imperative to optimize the tertiary industry to develop tourism industry.Developing the tourism industry can not only revitalize the economy of the surrounding areas,but also promote the protection of the ecological environment.Tourism industrial space layout is a type of tourist resources in some area,the related industry categories,the correlation between industrial distribution and industrial layout planning,whether it is reasonable or not directly related to the regional economic development level and speed,the ecological environment,optimal allocation of resources,etc.,reasonable space layout of the tourism industry can play a dual role for the sustainable development of economy and the environment coordination,.Taking Shimian county of Ya’an city as a case study,this paper studies the spatial layout pattern of tourism industry with the help of GIS kernel density analysis,network analysis,analytic hierarchy process,qualitative and quantitative analysis and "point-axis" theory.Firstly,the research objects of tourism industry are defined as tourist attractions,catering industry,accommodation industry,entertainment and shopping industry,and the development status,spatial distribution type,spatial distribution quantity,tourism industry category and other relevant information are analyzed by GIS kernel density analysis.Secondly,the AHP analytic hierarchy process is used to obtain different weight indexes of tourism industry in Shimian county,and the weighted abundance model of tourism industry is built on the basis of the tourism industry abundance model,which is used to define the "node" of tourism industry.Then,in the GIS network analysis,OD cost matrix analysis method is used to analyze the accessibility of the tourism industry,which is used to define the "axis" of the tourism industry.Finally,under the guidance of "point-axis" theory,the spatial layout plan and development strategy of tourism industry are determined.The results show that :(1)Shimian county is rich in tourism resources,and the tourism industry is distributed in a state of "large dispersion and small concentration" in space.(2)The condition of traffic and the tourism industry cluster correlation is higher,such as the county downtown tourist attractions are less,however,it’s traffic conditions are better and catering,accommodation,entertainment,shopping agglomeration degree is higher.On the contrary,in other places that far away from the center of the county,there are more tourist attractions but their transportation as well as related industrial supporting facilities are poor;(3)Planning the tourism industry in Shimian county as the spatial layout mode of "five points,three axes,three districts,one corridor and one belt",that is,the five-level development node,three-level development axis,three tourism development areas,an ecological corridor and a national cultural transition zone.Finally,according to the research conclusion,the development strategy and development sequence of the tourism industry are proposed. |
