Spatial Heterogeneity Of National Above-4A-grade Tourist Attractions Based On GWR In Sichuan

Spatial heterogeneity refers to the lack of regional balance in geographical space,and the existence of spatial geographic structures such as core and marginal areas,developed and backward areas,which leads to the spatial differences in regional development,industrial structure,tourism activities and scenic spots distribution.By 277 more than 4 a grade scenic spot of sichuan province as the research object,in the city state of the surface domain unit,in a natural tourism resources,cultural tourism resources,economic development level,transportation,tourism,investment for the influencing factors,and uses the method of fixed geographical spatial regression model,on the one hand,proved that the model method in the research area of spatial heterogeneity has the scientific nature and rationality,on the other hand,from the perspective of spatial heterogeneity to explore the regional differences and its influence factors of tourism scenic area number,for the city state and the province's tourism development has the reference value of quantitative indicators.The results show that :(1)the tourist attractions above grade 4A in various cities and prefectures are widely distributed and unbalanced.From the perspective of spatial agglomeration,they are mainly distributed in the form of "large dispersion and small agglomeration",including single core distribution,double core distribution,strip distribution and random distribution.(2)by means of transportation,cultural tourism resources,natural tourism resources,regional economic development level,investment of five factors analysis,using geographically weighted regression method to build the scenic area spatial heterogeneity model,and through the test of goodness of fit of the model,to illustrate the scenic spots of the building space heterogeneity model has the scientific nature and rationality;(3)the order of influencing factors on the number of tourist attractions above grade 4A in sichuan is as follows: traffic conditions > cultural tourism resources > natural tourism resources > tourism investment strength > economic development level,and the five factors have obvious positive driving effect on the number of tourist attractions.The traffic condition is the factor that has the greatest influence on the scenic spot,which presents the spatial distribution trend of "decreasing from south to north and from east to west in turn".Cultural and natural tourism resources present the distribution situation of "high in the south and low in the north";Tourism investment intensity presents the distribution situation of "north high south low west high east low";The level of economic development shows the distribution characteristics of "descending successively from southwest to central to northeast".Finally,according to the "large scattered and small agglomeration" pattern of the spatial distribution of tourist attractions above sichuan 4A class,it proposes to build a regional transportation system and improve the construction of panxi corridor.Deeply excavates the cultural connotation,enhances the south sichuan tourism spot;Relying on natural resources and landscape,the construction of south sichuan tourism brand;To improve the level of economic development and expand the tourism market of the three prefectures;To guide the direction of tourism investment and improve the optimization and promotion of five scenic spots in the northwest sichuan tourism cooperation,so as to enhance the internal impetus of sichuan tourism and realize the goal of sichuan province to accelerate the construction of a strong tourism economy province and an important tourism destination in the world.
