Enlightenment on the Spatial Characteristics, Interior Layout and Design of the Traditional Dwellings in the Dai Villages in Xishuangbanna

The Dai culture has a long history. The bamboo building is the original form of the Dai stilt style architecture. It has the original shape, simple structure and convenient construction. Conducting on-the-spot investigations on the Xishuangbanna Dai villages, exploring the remains of the traditional residences of the Yi villages, the types of buildings, the regional characteristics and the problems of the Yi people's residences, the authors briefly introduce the geographical environment and settlement space of the Yi villages, and focus on the spatial features and interior layout of traditional residences of the Dai villages. The results show that the Dai people's dwellings not only contain the material requirements of the Dai people's survival, life, production and aesthetics, but also the spiritual factors, beliefs, contexts and psychology formed by the national culture. Researchers need to analyze the regional characteristics, spatial characteristics and indoor layout of the Dai people's residences in an all-round way, and combine the pace of the times, develop and innovate, and explore the traditional residential design strategies and methods combining nationality and time.
