Evaluation of attraction and spatial pattern analysis of world cultural and natural heritage tourism resources in China.

The attraction of tourism resources is very important to promote the sustainable development of tourism industry. This study takes China's world cultural and natural heritage as the research object, and constructs an attractiveness evaluation system for China's world cultural and natural heritage tourism resources by collecting user feedback data from three major travel OTA platforms. At the same time, ArcGIS 10.7 software was used for spatial autocorrelation analysis and kernel density analysis to explore the spatial distribution pattern of tourism resource attraction. The results show that China's world cultural and natural heritage can be subdivided into 5 main categories and 10 sub-categories. From the perspective of spatial aggregation, only the Moran's I index of tourist resource points showing a significant spatial aggregation feature. This study is helpful to reveal the weaknesses of tourism resource points and provide reference for sustainable development of attraction and optimization of tourism planning and management.
