Abstract:The China-ASEAN Cultural Corridor is a key carrier of civilizational mutual learning under the Belt and Road Initiative. This study employs a comprehensive genealogical approach to trace the historical evolution and cross-border connections of Guangxi's traditional gardens, systematically analyzes them through a multidimensional theoretical framework, and reveals their cultural connotations, risk causes, and potential protective mechanisms through in-depth case studies. The research aims to provide theoretical support and practical pathways for cultural exchange within the China-ASEAN Cultural Corridor. The research uncovers the dual symbiosis of 'Han-style ritual systems' and 'Zhuang-Dong natural aesthetics' as the core characteristics of Guangxi's traditional gardens, along with their 'fragmentation' dilemma. By examining cross-border interaction mechanisms from three dimensions—technical evolution, symbolic restructuring, and ecological synergy— it dissects the 'defensive-trade' genetic erosion and excessive commercialization risks arising during modernization. Finally, it designs a systematic collaborative mechanism encompassing a 'heritage community' governance framework, a unified standard digital museum, and 'community garden guardians' tools, elucidating their application pathways through three case studies in China, Vietnam, and Laos.
