Abstract: Establishing a natural reserve system dominated by national parks is an important measure for the construction of China's ecological civilization. The main goal of the construction of national parks is to strengthen the protection of the authenticity and integrity of the natural ecosystem, realizing ownership by the state, sharing by the whole people and inheriting from generation to generation. It is very important for guarantee of national ecological security and promotion of harmonious coexistence between man and nature. Public participation and cultural propaganda is therefore one of the core contents of national park construction. The authors discussed the status quo of publicity of Shennongjia National Park, and proposed some recommendations for propaganda of national parks from the perspective of public participation and citizen science, science communication and niche communication. To promote the overall image and brand value of national parks, the propagandizing processes should include agenda setting, content production, platform construction, information exchange and ecological well-being sharing. This paper could provide a reference for the construction and publicity of China’s national natural reserve system.
