Abstract: Residential buildings adapt to the natural environment to form the basic characteristics of architectural style, and under the influence of the human environment, they develop unique features of architectural style. The differences in architectural professional factors significantly determine the professional characteristics of architectural style. Based on this, this paper analyzes the multi-level factors that affect architectural style, explores their impact mechanisms, and constructs the steps and methods for multi-factor comprehensive architectural style zoning. Combining samples of traditional villages and residential buildings in Sichuan, the architectural style of traditional villages and residential buildings in Sichuan is divided into 5 major regions and 14 sub-regions, and the characteristics of architectural style in each region are summarized.
