Abstract: 【Objectives】To solve the problems of unclear system orientation, unscientific legislation, imperfect registration content, and immature registration platform construction of the registration system of natural resources in the national parks of China. To provide a feasible path for improving the registration system of natural resources in the national parks of China. 【Methods】The methods of empirical analysis and comparative research were utilized to compare the current natural resources registration system of national parks and the unified natural resources registration system based on ecological protection. This paper studied the design of national park systems in the United States, India, Canada, and other countries based on legal norms and institutional reality. 【Results】Based on the Overall Program for the Establishment of National Park System released in 2017, the registration objectives, registration targets, ownership subjects, and other contents of the natural resources registration system of national parks were analyzed. It was found that the norms of the natural resources registration system of national parks were special, and the current status of the system’s implementation was faced with various problems and challenges. 【Conclusions】The paper concluded that ecological protection should always be the primary goal, and based on creatively absorbing and learning from the relevant institutional experiences of the United States, India and Canada, we should clarify the unique position of the registration of natural resources in national parks, construct the legal system of national parks, improve the content of the registration of rights and strengthen the construction of the registration platform, etc., to construct the system of natural resources in national parks, which will promote the realization of the goal of building an ecological civilization.
