The Role of "Oral History" Method in the Study of Vernacular Architecture: The Interview with Chen Hongyou 口述史方法在风土建筑研究中的作用——以访谈重庆江津陈宅后人陈洪佑为例

风土建筑史研究注重文献和实物的二重证据，对于一些保存状况堪忧、民间文献欠缺的风土宅院，口述史方法在研究建造背景、再现建筑场景和复原建筑形式三方面发挥了重要作用。文章以访谈重庆江津陈宅的后人陈洪佑为例，就以上三方面作用展开：首先，结合口述信息和地方志材料，梳理陈宅的修建过程和建造背景；其次，结合平面布局和关于各空间功能仪式的口述内容，分析其空间形制特征；最后，结合口述史和周边风土建筑特征对陈宅进行修复探索。

Research on the history of vernacular architecture lies on the dual evidences of both literature and architecture. For some vernacular houses that are poorly preserved and lack of folk documentation, the “oral history” method plays an important role in investigating construction background, reproducing architectural scenes, and recovering architectural form. This article illustrates the three roles of the “oral history” method through the interview with Hongyou Chen, a descendant of the Chen family who built and lived in his courtyard house for generations. First, though combining the oral information and folk literature, the article sorts out the construction process of the Chen family residence and the family’s migration background. Second, it analyzes the layout feature of the house by mapping functions and rituals known from the interview. Third, it presents a hypothetical reconstruction design of the house based on its status, the oral information collected, and the characteristics of surrounding vernacular dwellings.
