Abstract: The Zuojiang River and Youjiang River, tributaries of the Pearl River in southwest Guangxi, are the origin of the Zhuang ancestors. The Zhuang ethnic culture system of southwest Guangxi is dominated by the unique 'Na' culture, and 'Na space' is the typical spatial form of traditional villages in the region corresponding to the Zhuang ethnic culture. Based on the purpose of systematically summarising the ethnic cultural system of the Zhuang minority and establishing the overall Zhuang village spatial morphology cognition, the study uses space syntax axis analysis to quantify the spatial morphology of the sample villages. The Zhuang of southwest Guangxi can be divided into stripes, clusters, and scattered clusters according to the overall morphology, which correspond to the linear, the intersection of village and nature, and the compact spatial relationship represented by 'Na space'. Combined with the fact that the overall spatial comprehensibility values of traditional Zhuang villages are all under 0.7, the difference between the ethnic nodes 'Na space' and the core axis ranges from 0.05 to 0.5, with certain fluctuation and a large fluctuation range. The quantitative results suggest that the Zhuang village space is a weak boundary in overall form, strong order in spatial pattern, high node space. It suggests that Zhuang village space is an ethnic characteristic 'Na space' with weak boundaries, strong spatial order, and high flexibility in node space distribution. It is hoped to provide reference for future research on the spatial patterns of traditional villages of ethnic minorities and Zhuang villages.
