With the development of society and economy, human beings have shown a fervent desire for spiritual products. Given that ecosystems have cultural services, the research interest on this aspect has been increasing in recent years, which is reflected in the number of published papers. This paper attempts to clarify the research context of international ecosystem cultural services by compiling literature and materials related to ecosystem services and applying statistical analyses. Using the Web of Science core collection database, 1530 papers were analyzed. This analysis led to the identification of research trends, time period characteristics, author distribution, institutional distribution, and periodical distribution of these sample papers. The results show that the research of cultural ecosystem service gradually evolved from the discipline of ecology to an interdisciplinary research field, including ecology, geography, management science, and sociology. In the near future, research work on cultural ecosystem services will focus on six major directions, which are monetary evaluation, management and application, index system, value mapping, recreation function, and aesthetic function of cultural ecosystem services.
