Abstract: In the context of rapid urbanization and climate change, there is significant uncertainty in the regional ecological patterns upon which coastal traditional villages rely. It is necessary to enhance the adaptability of traditional villages from a regional perspective. Taking a typical area in Shandong Province as an example, this study explores pathways to enhance the adaptability of coastal traditional village systems based on the Adaptive Cycle Theory. This paper constructs an evaluation index system at two levels: regional ecological patterns and cultural landscape units. Within these levels, three dimensions are considered: village unit attributes, regional spatial correlations, and dynamic evolutionary trends. This system is designed to discern the spatiotemporal evolution trends of coastal natural ecosystems, identify the adaptive cycle stages of traditional village units, analyze the relationship between village adaptation and regional ecology, and propose collaborative enhancement strategies. The results indicate: Firstly, urban and rural construction land expansion is the primary source of risk affecting the ecological foundation of coastal rural areas. Secondly, from 2000 to 2020, the adaptive stages of coastal traditional villages underwent a leapfrogging cyclic process, primarily transitioning from the release and assimilation stages to the development stage. Thirdly, the spatial adaptability of coastal traditional village systems can be classified into five grades: high, medium-high, medium, medium-low, and low. Finally, it is recommended that the adaptability of coastal traditional village systems be improved from three aspects: classification, grading, and time series analysis This study aims to improve the risk assessment methods for coastal heritage and provide new ideas for the regional protection of traditional villages.
