This study focused on the Jeju Batdam, a traditional landscape system designated as a GIAHS(Globally Important Agricultural Heritage System) site, which has not only supported the agricultural system but also the lives of Jeju Island residents. Despite its mixed value, there has been a lack of research consideration on this subject. Therefore, this study aims to highlight the historical and cultural significance of Jeju Batdam as a cultural landscape by applying the phenological calendar, a time-series analysis method for landscapes, to interpret its value. The study specifically targets Gwiduk 1-ri, Hallim-eup, Jeju Special Self-Governing Province, to understand cultural aspects related to Batdam, the lifestyle of local residents, and their daily lives through interviews and field surveys. The cultural landscape characteristics of Jeju Batdam, as interpreted from the study results, include: ‘Diversification of crops due to environmental changes’, ‘Places of childhood memories and everyday experiences embedded in lives of residents through Batdam’, ‘Inheritance of the Batdam spirit reflecting locality and community culture’, and ‘Development of new value through the utilization and connection of Batdam resources’. Through this, the study presents a new perspective on understanding the dynamic meanings and cultural landscape value of Jeju Batdam as it has evolved over time. It suggests the need to go beyond a system that focuses solely on the preservation and protection of Batdam as a physical artifact, and instead recognize and preserve its hidden cultural landscape value as a dynamic landscape. This study is expected to serve as a useful framework for identifying the significant past values of Batdam and for the future sustainable preservation and revitalization of Batdam. 1)
