Research On The Similarity Principle Of Self-built Residential Buildings Based On Three Case Villages

In the past 20 years,China's rural construction has developed rapidly,and the locality and regional expression of architecture have received more attention.Regional research has been analyzed in many aspects such as self-organization and adaptive theory.As an important feature of regional research,similarity has not been fully studied.In a certain geographical area,similar phenomena presented by self-built houses are generally recognized by people,but similar causes are ignored by researchers.This paper attempts to extend the similarity theory to the research scope of selfbuilt houses.Based on the principle of similarity formation,this paper focuses on the analysis of the internal factors of rural self-built houses in different evolution stages,and tries to summarize the similarity of rural self-built houses.The mechanism and the formation of design guidelines to guide the construction of village housing.The full text is divided into six chapters.The first chapter expounds the background of the research,sorts out the research status of rural houses and similar theories,clarifies the purpose and significance of the research,defines the scope and objects of the research,and constructs research methods.The second chapter elaborates the related concepts of similarity theory,introduces the principle of similarity formation,clarifies the similar level and limiting factors of self-built houses,clarifies the evolution classification of rural areas at different development stages,determines the research villages,and constructs a threedimensional research system.The third to fifth chapters respectively discuss the evolutionary rules of traditional farming,government-regulated,self-built commercial villages and self-built residential groups,and analyze the planar function,material structure and decorative components of self-built houses under different influence factors.,the reason for the formation of similar phenomena.The sixth chapter summarizes the internal factors of the similarity of rural selfbuilt houses,and forms the similarity generation mechanism by the similarity forming internal factors to control the elements,and clarifies the design guidance and control points of the village under different development stages and different spatial scales.Through specific rural empirical research,this paper collects and draws a large number of drawings and interview data,and starts from the limiting factors that affect the similarity of village space and self-built houses,and explores the similarity formation mechanism of rural self-built houses.The research of this paper not only has important theoretical value for case study in rural areas,but the research method of similarity has good demonstration significance for other areas of China.
