Protecting and preserving the agricultural heritage, folk culture and ecological environment of traditional villages is a key element in advancing the strategy for comprehensive rural revitalisation. This paper constructs a theoretical framework for tourism symbiosis, examines the level of tourism symbiosis in the 13 national-level traditional villages of Jia County, and proposes strategies for tourism development. This study employs the Analytic Hierarchy Process (AHP) and Technique for Order Preference by Similarity to an Ideal Solution (TOPSIS) method, alongside spatial analysis techniques such as the Hotspot Analysis, to reveal the levels of tourism symbiosis in traditional villages and their spatial distribution. The results indicate that traditional villages are distributed along the Yellow River, with a linear clustering pattern particularly evident in the central region of Jia County; the overall level of symbiosis exhibits a spatial pattern of higher levels in the north and lower levels in the south, with uneven levels across various dimensions; The traditional villages are categorised into four symbiotic models: comprehensive advantage-led, cultural corridor-dependent, ecological and cultural tourism potential, and low-development conservation. Based on these categories, strategies are proposed to deepen the exploration of local culture, promote industrial integration and regional collaboration, prioritise ecological conservation and environmental restoration, and establish distinctive brands through the rational utilisation of surrounding resources. The research framework and conclusions of this paper provide methodological references and practical insights for the concentrated and contiguous protection of traditional villages, as well as for research on rural revitalisation and sustainable development.
