Abstract: The interpretation system of national parks serves as a crucial bridge connecting natural heritage with public awareness. Visual design, as one of the most intuitive and expressive mediums for information dissemination, transcends the conventional scope of "aesthetic enhancement". Focusing on the design practices of the interpretation system for the Asian Elephant National Park Candidate, this study develops a systematic and scientific framework for the visual design of national park interpretation systems. This framework integrates diverse visual elements, including logos, IP character, symbols, color schemes, typography, and stylized illustrations. By effectively enhancing the management efficiency and educational function of national parks, the proposed framework holds significant value for advancing national park development, enriching visitor experiences, and strengthening the brand identity of national parks.
