Abstract: Through the relevant data provided by the "Baidu Index", the paper analyzes the spatial-temporal characteristics of Huangshan Tourism's network attention in 2019 and 2020, the years chosen as the time frame before and after the outbreak of the epidemic. The results show that the peak of weekly attention arrived early, indicating that people are more cautious; the peak of tourism accommodation and travel search has been delayed, proving a significant impact of the epidemic on tourism. Monthly analysis shows that the attention has decreased significantly after the epidemic. People's spatial preferences for tourism in Huangshan have gradually shifted to the eastern region, and most of the areas with great changes in network attention to Huangshan tourism are the "hard-hit areas" and their surrounding areas. The results of this paper are helpful for the tourism industry to deal with public health incidents in a timely and reasonable manner, and are also of significance to the recovery and promotion of tourism after the epidemic.
