Abstract: Objective Cultural perception has gradually become an important value component of cultural landscape in parks. Visitors' cultural perception of a park directly affects their impression and experience of the park. Exploring tourists' perception of cultural landscape is of great significance in improving the image of park and conveying the spirit of place.Methods Taking Tianjin Beining Park as the research area, this research constructs a park review database by capturing review data from four major travel social networking platforms in China, and conducts multi-level word frequency analysis on review texts and IPA(importance-performance) analysis on tourists' emotional tendency towards and cultural perception of the park, which is conducive to interpreting tourists' landscape perception from the bottom up.Results The results show that local tourists are the main users of Beining Park, and the park's landscape has become part of their collective memory. Local tourists attach importance to their childhood memories and have a strong sense of identity and concern for the park's landscape style and features and sense of age, but lack in-depth understanding of the historical figures and events involved in the park and their connection with the city. Tourists recognize newly built garden buildings and cultural activities in the park to a certain extent, but pay less attention to them.Conclusion Beining Park is an important part of the urban historical and cultural landscape memory of Tianjin. Residents and tourists have high concern and recognition for the park's historical and cultural attractions, while paying less attention to subsequent landscape alteration or renewal, which may trigger negative emotions among them. Preserving the park's historical attractions, emphasizing the style and features and historicity of such attractions, and promoting related traditional activities can improve the historical and cultural image of the park and attract more attention and recognition from tourists. This research confirms the usability of online review data in cultural perception, and provides a basis for subsequent renewal and preservation of cultural landscape in urban parks.
