Abstract: China is building a nature reserve system with national parks as the main body. As a breakthrough to deepen the reform of the ecological civilization system, the national park system has become an important part of a new round of national strategy. This paper systematically combs the development of the theory and practice of national park construction in China and divides the process of national park construction into three stages: The early stage of practice and theoretical exploration (1956—1995), the stage of local practice, and theoretical reference (1996—2012), the stage of national promotion and theoretical development (from 2013 to the present). And the theoretical and practical achievements of each stage were carried out, to reveal its internal evolution law more scientifically and provide scientific references for the construction of national parks in the future.
