Abstract: Guijiang River Basin is adjacent to Hunan and Guangdong Provinces. In the marginal zone of Lingnan culture, it is influenced by local culture and surrounding cultural centers and thus demonstrates mixed cultural characteristics. These mixed cultural characteristics are visible in the residential buildings. The master house of a residential building, a residential space with three rooms, was analyzed by combining functions, space, and construction. The structures of the master houses were identified. Moreover, each structure was located in geological planning and the distribution rules of the master houses were further interpreted. This study demonstrates the richness and diversity of traditional architectural cultures in Guijiang River Basin through the basic unit of the master house.

Key words: Guijiang River Basin, marginal zone, main houses, typology research

摘要： 桂江流域毗邻湘、粤两省，作为岭南文化边缘区，本土文化的遗留加上周边文化中心区的影响，使得该区域呈现出混杂性的文化特征，这种混杂性也同时反映到了民居建筑中。以民居空间中带祭祀功能的三开间建筑——主屋为研究对象，结合功能、空间与建造，建构主屋类型，并将各个类型置于地理区划中并进一步解释主屋分布规律的形成原因。试图通过主屋这个基本单元，初步展示桂江流域传统建筑文化的丰富与混杂。
