Study on the Spatial Coupling between Highway Traffic Accessibility and Tourism Economic Linkage——Taking Hunan Province as an Example
Based on the weighted average travel time model,gravity model and spatial autocorrelation analysis model,the coupling mechanism of road accessibility and tourism economy in Hunan province is analyzed.The results show that the spatial distribution of road accessibility in Hunan province has significant core-edge characteristics,which is high in the central part and low in the north and south part.The spatial distribution of the total volume of tourism economic connections in Hunan province shows the characteristics of"center-periphery"circle structure with Changsha as the core,and the to-tal volume of tourism economic connections in Changsha city has an absolute advantage.The coupling coordination degree of road traffic accessibility and tourism economy in Hunan province is at a medium and high level on the whole,but the polarization characteristics are obvious,showing the core polarization and"center-periphery"spatial characteristics.The spatial correlation pattern of the two systems show a significant global positive spatial agglomeration;It also puts for-ward relevant countermeasures and suggestions from perfecting road network construction,eliminating regional trade bar-riers,optimizing tourism spatial structure and strengthening policy guidance
