Ecosystem cultural services are defined as the spiritual and cultural benefits that humans obtain from ecosystems. The cultural services of national parks include scientific research,education,and recreation. The value assessment of these ecosystems could provide scientific supporting for park planning and management. This paper presents a systematic review of relevant studies on the classification of ecosystem cultural services and their valuation methods in national parks. It also outlines the current status of research on the primary cultural services and their valuation within national park ecosystems. Finally,it puts forward a research outlook in terms of the assessment object,assessment content,assessment method,and transformation of the assessment results. The valuation methods of ecosystem cultural services fall into two categories: the stated preference method and the revealed preference method. These methods can be further classified into those that quantify value and those that assess object quality. National parks primarily offer cultural services such as scientific research,education,and recreation. The valuation of these services is continuously evolving,with a growing range of methods and approaches. The results of these valuations offer a multifaceted perspective on the study of ecosystem services in national parks. The development of this field of research will be driven by four key developments: the expansion of comparative case studies to encompass a wider range of assessment objects; the diversification of cultural services valuation; the integration and innovative use of quantity and value assessment methods; and the expansion of the practical significance of cultural service value assessment.
