| With the development of tourism diversification,rural tourism with the main functions of being close to nature and relaxing body and mind is being sought after by Chinese people.The development of rural tourism not only meets the growing spiritual needs of the people,but also stimulates the vitality of rural areas and effectively promotes rural development.As the birthplace of Chinese farmhouses,Sichuan Province is rich in rural tourism resources.Sichuan Province’s tourism plan clearly proposes to build Sichuan into a nationally leading and internationally renowned destination for rural leisure and vacation tourism,accelerate the agglomeration and large-scale development of rural tourism,and build Contiguous development pattern of agglomeration.However,the spatial structure of the rapidly developing rural tourism has not yet been clarified.As an important form of rural tourism,star-rated farmhouse attractions have developed rapidly.The study of its spatial evolution structure is of great significance for the optimization and development of rural tourism.In view of this,this paper takes the 2010-2018 star-rated farmhouses announced by the Sichuan Provincial Department of Tourism and Culture as the research object.Based on fractal theory,this paper analyzes the star-rated farmhouses in Sichuan Province and five major tourist areas from the perspective of cluster dimension,grid dimension and correlation dimension.A multi-scale empirical analysis was carried out on the spatial structure characteristics of scenic spots.And based on the multiple linear regression model,the influencing factors of the spatial distribution density difference of star farmhouses are briefly analyzed,and on this basis,the existing problems and optimization measures of the spatial structure are put forward,in order to provide a basis for the coordinated development of regional rural tourism.The main conclusions of this study are as follows:(1)Based on the fractal theory,the agglomeration,equilibrium and correlation of the rural tourism destination scenic spots in Sichuan Province and the five major tourist areas are measured and analyzed.The results show that the spatial structure of the rural tourism destination scenic spots in Sichuan Province and the five major tourist areas is self-assessed.Fractal features have existed since then,the scale-free interval has gradually expanded,and there is a trend of self-organizing evolution.(2)From the perspective of agglomeration dimension,from 2010 to 2018,the fluctuation of star farmhouse attractions in Sichuan Province and the five major tourist areas was close to 1.78,and the spatial distribution structure approached the limited diffusion group agglomeration model.The fractal structure is becoming more and more complex,and there is a multi-fractal evolution.According to the evolution trend of fractal structure and the strength of central point agglomeration,The spatial structure of rural tourism destinations in Sichuan Province is compact.From a local point of view,the spatial structure of rural tourism destinations in the northeastern Sichuan tourist area,the northwestern Sichuan tourist area,and the Panxi tourist area are divided into compact ones;the core area of Chengdu Plain and the tourist area of southern Sichuan The spatial structure of rural tourism destinations is classified as loose.(3)From the perspective of grid dimension,the fluctuation of grid dimension in Sichuan Province and the five major tourist areas has become larger,and the grid information dimension is always smaller than the grid capacity dimension,indicating that the spatial structure of rural tourism destination scenic spots in Sichuan Province and the five major tourist areas In the process of organizational evolution,there is a phenomenon of local agglomeration around a certain center,and the evolution of its spatial structure has the characteristics of relative agglomeration and equilibrium.(4)From the perspective of correlation dimension,the spatial connection between star-rated farmhouse attractions in Sichuan Province is enhanced,and their spatial distribution is concentrated along a certain linear geographic object,which has initially formed a spatial development axis and has great development potential.Among the five major tourist areas,the spatial correlation dimension of the tourist area in Northwest Sichuan is small,and the star farmhouses are highly concentrated in a certain place,indicating that the infrastructure construction in this area needs to be strengthened.(5)From the results of multiple linear regression,in general,the star farmhouse in Sichuan Province is a kind of resource-based farmhouse,and its spatial distribution density depends on the number of A-level scenic spots.In addition,it is closely related to the socio-economic level,and natural geographical factors affect its spatial distribution.The distribution density has a negative impact,and various research factors have different influences on the interior of the region.The spatial distribution density of star-rated farmhouses in the core area of Chengdu Plain,the tourist areas in northwest Sichuan,and the tourist areas in Panxi is mainly affected by the endowment of tourism resources.The spatial distribution of star-rated farmhouses in the tourist areas in northeastern Sichuan is limited by terrain,and the spatial distribution of star-rated farmhouses in the tourist areas in southern Sichuan is affected by employment.(6)At present,the spatial structure of rural tourism destination scenic spots in Sichuan Province is gradually optimized,but the spatial development degree of each area is significantly different.Therefore,in the future development,Sichuan Province should further explore the agglomeration effect of central points and cultivate secondary agglomeration centers;build “π” Shape the spatial development axis of rural tourism destinations;optimize the internal spatial structure of the scenic area system of rural tourism destinations. |
