Abstract: Rice terrace provides multiple ecosystem services. A global systematic review could improve the research and understanding of its ecosystem services. Based on the Millennium Ecosystem Service Classification System and systematic literature analysis, we summarized the research progress of global rice terrace ecosystem services. The literature on global rice terrace ecosystem services is mainly from China, Vietnam, and Philippines. Studies in China mainly use the value assessment method (VAM) while studies in foreign countries emphasize on physical assessment method (PAM) for assessing ecosystems services. The VAM results of Chinese rice terraces in four sites show higher regulating and supporting services than other ones. It is difficult to compare with each other due to different spatial units and calculating methods used in the studies. With respect to physical assessment, studies on regulating services were carried out on soil erosion, disaster, and pest regulations, studies on supporting services were carried out on the cycling and transformation of silicon that is beneficial to rice growth, and studies on provisioning services mainly focused on the impact factors for rice growth and its simulation prediction. At the landscape scale, increasing the number of patches planted with other crops beside rice could enhance all kinds of ecosystem services. The analysis framework based on ecosystem service matrix and mapping has promising application prospect. Future research should focus on the multiscale evaluation system of rice terrace ecosystem services, the tradeoff/synergy relationships from aspects of service formation mechanism, and the relationships among the pattern, process, service, and human well-being at landscape scale.

Key words: quantitative value assessment, quantitative physical assessment, trade-off, pattern.
