Tourism ecological security is the basic guarantee for the sustainable development of tourist sites, Huizhou Cultural and Ecological Reserve is an important area for the im-plementation of ecological protection in China, and it is of great significance to carry out research on tourism ecological security. The study adopted the DPSIR model to construct a comprehensive evaluation index system for tourism ecological security and used entropy value-TOPSIS and ArcGIS software to analyze the inter-annual changes and spatial change characteristics of tourism ecological security in the study area. The results show that: firstly, the comprehensive index of tourism ecological safety in the study area from 2010 to 2021 shows a trend of “decreasing-increasing" and an overall increasing trend; secondly, all the sub-systems show an increasing or stabilizing state in recent years during 2010–2021; the state and response sub-systems show an increas-ing or stabilizing state in recent years; and the state and response sub-systems show an increasing trend in recent years. Secondly, all the subsystems showed an increase or stabilization in recent years between 2010 and 2021, and the state and response sub-systems are the main systems to improve the ecological safety of tourism in the study area; thirdly, the difference in the level of ecological safety of tourism in each county of the study area increased and then narrowed from 2010 to 2021, and the change of safety level usually shifted between neighboring levels, and the probability of transfer-ring across the levels was relatively small. , Shexian County, Yixian County, Qimen County, Tunxi District, and the tourism eco-safety level of Huangshan District, Hui-zhou District, Jixi County, and Xiuning County increased at a faster rate than other counties. The study further extends the scale to the district and county level, tries to explore the relevant factors affecting the ecological security of tourism, and proposes countermeasures for the sustainable development of the study area based on the re-sults, which will bring some reference value to the ecological governance and policy formulation of this kind of research.

Tourists’ environmental perception is the decisive factor of cultural tourism experience. Although this topic research is relatively common, there are essential differences between different theme tourism areas. This study selects the national Huizhou Cultural and Ecological Reserve in China as the research object, which has a diverse cultural field, a wide range of researchable levels, and research theoretical support, and focuses on the evaluation of tourists’ environmental perceptions of cultural-themed tourism reserves. The research is in line with the basic consensus of the international community on the relationship between NRM conservation and sustainable development and has a positive significance for cultural conservation. In this study, nine indicators were constructed from the three dimensions of cultural perception, environmental perception, and emotional perception, including mental pleasure, experience comfort, audiovisual richness, cultural awareness, cultural diversity, cultural influence, facilities completeness, environment tidiness, and travel convenience. Questionnaires (283) were distributed, 260 of which were valid. The analytic hierarchy process (AHP) and entropy method were used to study the cultural context perception of Huizhou Cultural Ecological Reserve. The Cronbach coefficient was 0.977, the KMO value was 0.953, and the validity was 91.87%. The research results show that, first, tourists’ perception level from high to low is cultural perception (0.351), environmental perception (0.349), and emotional perception (0.301). Secondly, the factors most strongly perceived by tourists are tourism convenience (0.129), cultural influence (0.126), cultural diversity (0.118), and facilities completeness (0.115). Thirdly, improving tourists’ spiritual pleasure, experience comfort, audiovisual richness, cultural recognition, and environmental cleanliness is conducive to promoting tourists’ perception and experience.
