It is a major measure of China's ecological civilization to establish a protected area system with national parks as the main body. As a widely recognized nature protection method, national park is welcomed by the whole world. This research analyzed national park establishment experiences in America, Canada, German, and Japan, etc. which are well developed. The results show that (1) the primary object of national park is nature conservation, and it provides places for the public to enjoy nature. (2) The evaluation indexes and criteria are mainly natural landscapes/heritages, ecosystems, biology/important habitats, areas, natural regions/environments, and cultural landscapes, etc. (3) The national park patterns are divided into ecological zoning type, community construction type, and resources-oriented type according to different resource conditions, and functions and objects. This research put forward suggestions for national park development in China based on the foreign experiences and China national conditions: (1) to identify the functions of national parks; (2) to establish national park evaluation criteria, methods, and indexes, such as national representative, integrity, authenticity, importance of ecological location, and historical and cultural value; and (3) to divide China into eco-geographic regions for national park planning and analyze the spatial patterns of ecosystem, key protected species, natural landscapes, and ecosystem services.
