Abstract: Protected areas reserves provide significant ecologic and economic benefits. In recent years, the ecosystem services assessment and valuation of protected areas have become hot issues in current ecology and environmental economics studies. Through systematic review of the historical progress of the ecosystem services assessment and valuation of protected areas, we reviewed research advances from the aspects of spatial scale, research objects, evaluation methods and indicators. In general, relevant cases of domestic and foreign studies basically covered different spatial scales such as national, administrative regional, natural geographic units and individual protected area. Researches were carried out on different protected areas of representative ecosystems such as forests, wetlands, grasslands and deserts, respectively. There were two mainly valuation methods adopted, the coefficient valuation method and the material quality valuation method. Meanwhile, different protected areas used different indicators in the four categories of ecosystem services such as supply, support, regulation and culture. However, there are still insufficient researches on assessment and valuation standard systems, time and space dynamics, and stakeholder relationship. Therefore, we suggest that further studies on the ecosystem services assessment and valuation of protected areas focus on:(1) Strengthen basic research and explore the ecological mechanism of ecosystem services. (2) Establish indicator system and improve technical methods for different types of protected areas, and carry out long-term dynamic monitoring of each indicator. (3) Strengthen the analysis of spatiotemporal dynamics and impact factors of ecosystem services, and use dynamic simulation models to predict value changes. (4) Fully consider the trade-offs between different stakeholders to make them play an important role in ecological compensation research. (5) Strengthen the application research of valuation results in the planning, construction, management and protection of protected areas.
