Abstract: National parks are natural areas that are established and managed by states or countries, designed to conserve natural resources and to provide well-being. There are many studies on the conservation, management and utilization of national parks. Ecosystem services derived from natural resources comprise an important foundation for human well-being. The analysis of the research advances of ecosystem services in national parks could provide reference for the development of China at this field and provide a theoretical basis for the establishment and management of natural reserve systems, including national parks. Focusing on the ecosystem services in national parks, we mainly review research progresses in five aspects: its relationship to biodiversity, the impacts from land use patterns and the underlying mechanisms, its responses and feedbacks to global climate changes, the quantitative assessments, and the tradeoffs of ecosystem services. We highlight the comprehensive, complex and heterogeneous characters of ecosystem services in national parks, and thereby propose that future works should be based on ecological theory, integrate social science, and strengthen the application of machine learning and spatial tools in the frameworks, methods and models in ecosystem services assessment. In the future, researches on the mechanisms underlying ecosystem services and the optimization of system models should be intensified comprehensively and broadly. Special attention should also be paid continuously on the dependency between ecosystem services of national parks and human well-being.

Key words: national park, ecosystem services, quantitative assessment.
