The characteristic of regional differentiation and impact mechanism of architecture style of traditional residence

Abstract: The protection of traditional villages and towns is one of the important tasks of new-type urbanization. However, the residential buildings that are tangible cultural heritage and cultural genes are the mainstay of traditional feature in traditional villages and towns, and the traditional villages and towns would have lost the carrier of the inheritance of cultural heritage, if their traditional residential buildings were missing. In this paper, we take the representative architectural landscape characteristic towns and villages as study cases to analyze their regional differentiation of architecture style, and explore the impact mechanism of their regional differentiation of architecture style. The study found that, firstly, there are 12 types of architecture style in Chinese traditional dwellings. The resulting architectural feature areas show that there are obvious differences in spatial distribution between north and south. The northern architectural feature area is divided into two sections with different sizes, and the southern architectural feature area has two "string of pearls" distribution. Secondly, there are obvious regional differentiations in the characteristic of Chinese traditional residential architecture in 5 aspects, namely, settlement environment, spatial layout, modeling style, building materials and detail decoration. Thirdly, from the impact mechanism of architecture style regional differentiation of Chinese traditional residential buildings, the natural environmental factors (including topography, landform, water system, climate, planting material, earth and stone) are the cornerstone of the formation of architecture style regional differentiation of traditional residence. The cultural factors such as the patriarchal ethics, fengshui concept and ethnic culture are the internal impetus of the architecture style regional differentiation of traditional residence. The cultural factors such as population migration, war defense and business economy are the extrapolation forces of architecture style regional differentiation of traditional residence.
