Research on the spatial distribution and influencing factors of B&Bs in Liangshan prefecture based on GIS spatial analysis and spatial econometric model

With the "14th Five-Year Plan" tourism development plan, the distribution of B&B has gradually become essential optimizing tourism spatial layout and promoting regional coordinated development. Based on the POI data and the GIS spatial analysis method, this paper analyzes the spatial distribution and influencing factors of B&Bs in Liangshan Prefecture. The results show that the spatial distribution trend of B&Bs in Liangshan is in the direction of "northeast-southwest", and the distribution of B&Bs has a high degree of aggregation, and the distribution is unbalanced. The spatial distribution of B&Bs showed a significant aggregation pattern, and formed a spatial distribution pattern with Xichang city as the core, Yanyuan County as the secondary core, Huili, Dechang and other places gathering in a small range. At the same time, the paper uses the geographical detector and the geographical weighted regression model to comprehensively analyze the factors affecting the spatial distribution of B&Bs in Liangshan Prefecture from the global scale and local scale. The results show that the spatial distribution of B&Bs is highly positively correlated with the density of scenic spots.
