With the deepening of domestic scholars’ understanding of Tibetan architecture, they have a more in-depth study of Tibetan architecture, including history, customs, religion, system, culture and so on. There are not only Weizang Tibetan area, Kangba Tibetan area and Anduo Tibetan area that we are familiar with, but also some little-known Tibetan areas, such as Jiarong Tibetan area, Baima Tibetan area and so on. According to the current situation, the relevant scholars in the academic circles constantly put forward that the research work should be specific, that is, to explore the Tibetan architectural culture of a certain area and a certain crowd to supplement and develop the research on Tibetan architectural culture, so that Chinese architectural culture can be more colorful. Therefore, in this article, it will expound the Jiarong Tibetan and its background factors—natural environment and social environment, and then based on the perspective of Architectural Anthropology, it will elaborate its architectural features and cultural connotation. At the same time, a new perspective of interdisciplinary research is put forward; that is, the methods of architecture and anthropology should be comprehensively applied to study the architectural culture of Jiarong Tibetan in Northwest Sichuan to obtain more in-depth research results.
