Tourist Perception Characteristics of the Rural Tourism Resource Supply System—A Case Study of Key Tourism Villages in Beijing

In the context of global rural sustainable development, tourist perceptions play a crucial role in rural tourism development. This study employs GIS, Geodetector, and LDA topic modeling approaches, taking key tourism villages in Beijing as the research object, to analyze the characteristics of tourist perceptions within the rural tourism resource supply system in the suburban areas of Beijing. The results indicate that, regarding homogeneous supply, tourists exhibit strong perceptions of the Great Wall Cultural Belt, elevation, distance to the city center, and intangible cultural heritage. These perceptions are influenced by visitor origins, coverage range, and the well-established experience model of “regional culture + landscape.” Concerning heterogeneous supply, tourists develop perceptions of landscape and geomorphology, historic sites and relics, pastoral landscapes and folk customs, outdoor recreation, leisure and consumption, and comprehensive categories, mainly shaped by the complementary cognition of rural authenticity and modernity. In terms of their relationship, homogeneous supply provides the foundational basis for the region, whereas heterogeneous supply contributes to the formation of distinctive village characteristics. Based on these findings, strategies are proposed to optimize rural tourism development in suburban Beijing, offering guidance for its sustainable development.
