Through analysis and research, it is found that the Baidu search index has a strong positive correlation with the tourist volume of scenic spots, and the tourist volume and popularity of scenic spots can be predicted by the search volume of Baidu. This conclusion is conducive to the coordination and control between the government and the scenic spots, the market analysis of tourism enterprises, and the tourists' comfortable experience of peak travel.
