Establishing National Parks in China is a crucial initiative for biodiversity conservation. It is essential to maximize the value of ecological products within them, benefit society, and promote a sustainable cycle of natural resource conservation and utilization to ensure the high-quality and sustainable development of these parks. Therefore, studying the pathways for realizing the value of ecological products is significant. This paper analyzes the geological settings, environmental conditions, and natural resources of the first batch of five National Parks in China (Three Rivers Source, Giant Panda, Northeast China Tiger and Leopard, Wuyishan, and Hainan Tropical Rainforest National Parks) and discusses the relationship between natural resources and ecological products in these parks. The ecological products are categorized as natural, semi-natural, and artificial based on human interference. Using land and water resources as examples, the paper explores the main factors influencing the value of ecological products and the various types of ecological products that natural resources can be transformed into. Additionally, based on the characteristics of ecological products, the paper presents three levels of pathways and methods for realizing their value and discusses the differences in value realization pathways for ecological products in national parks with diverse geological and natural backgrounds.
