Abstract:Abstract: For there exists many historic sites and relics, along with the relatively detailed documentation and the consistent emergence of archaeological discoveries, Chinese official buildings has attracted much public attention. However, the lack of primary sources and information makes the dwellings constructed before Ming Dynasty tough to identify. For example, the cases of dwellings built in Yuan is so scarce that the scholars find difficulty in carrying out related studies. Therefore, based on the architectural information expressed by the murals of the Yongle Palace which was painted during Yuan Dynasty, this article conducts a comprehensive investigation and study of the architectural parts of the murals. By analyzing the constituent elements and spatial layout features of the dwellings of Yuan Dynasty, it also sorts out their typological characteristics, spatial prototype and genetic composition. On this basis, this paper reveals the changing process and influence of the dwellings of Yuan Dynasty, and hence provides a new perspective for the further study of the architectural history of Yuan Dynasty which regards Yongle Palace as the dominant object.
