The perception of the value of Cultural Ecosystem Services (CESs) by tourists in national parks offers valuable insights into the spiritual relationship between individuals and these natural spaces, which is crucial for measuring the potential value of CESs in national parks and promoting harmonious coexistence between humans and nature. Using the Mount Huangshan National Park Creation Area as a case study, this paper employs methods such as literature review and brainstorming to develop dimensions, indicators, and items for the perceived value scale CESs among national park tourists. Based on an empirical analysis of 405 valid survey responses, a perceived value scale for CESs was constructed, comprising four dimensions-Cognitive Learning, Emotional Experience, Spiritual Benefits, and National Identity (CESI)-with 15 indicators. The results demonstrate the scale's strong reliability, construct validity, and criterion validity, indicating its robustness and applicability. The research results provide an effective measurement tool for evaluating the perceived value of CESs among national park tourists and offer a theoretical basis and practical guidance for realizing social and ecological benefits on national parks.
