Spatial Structure and Accessibility Evaluation of Tourism Resources in Nine Provinces along the Yellow River Basin
The spatial structure of tourism resources is the projection of the functional organization of the tourism system in space,and its spatial structure distribution characteristics and traffic accessibility evaluation directly affect the development trend of tourism in tourism destinations.Therefore,this study takes the scenic spots of grade 3A and above in 9 provinces and regions of the Yellow River Basin as the research object,and uses the nearest neighbor index,kernel density analysis,weighted network dimension and other methods to analyze the spatial structure of tourism resources in 9 provinces and regions of the Yellow River Basin.A tourism attraction coefficient model based on the Yellow River Basin is constructed,and a complete transport grid cost data set is built.The cost distance analysis tool is used to evaluate its transport accessibility.The research shows that:① The spatial distribution of tourism resources has obvious characteristics of spatial agglomeration of dense east and sparse west,and has obvious demographic and economic preferences,mainly concentrated in provincial capital cities.② The spatial agglomeration of tourism resources generally presents a north-south decentralized distribution pattern with Shandong Province as the apex.The overall pattern is approximately axisymmetric,with Shandong Province as the center,two regions as the support,and two centers in coordination.③ The overall traffic accessibility of tourism resources is good,and the high traffic accessibility tourism resources are mainly distributed in the provincial capitals and surrounding cities of the upper and middle reaches of the Yellow River Basin,forming a core periphery structure with its low value ring as the core and gradually weakening external accessibility.④ The traffic accessibility of tourism resources is different in grades and types.The higher the tourism resources are,the better the traffic accessibility is generally,and the humanistic tourism resources are generally better than the natural tourism resources.
