Study On The Forms Of Traditional Villages Of Jiarong Tibetans In Northwest Sichuan Based On Environmental Adaptability

The northwestern Sichuan region is an ancient place where the Jiarong culture was born and originated.It is also a region where many ethnic groups in China have exchanged and influenced each other in politics,economy and culture.Here,the traditional villages of Jiarong Tibetans with different forms and cultural diversity are scattered.From the beginning to the evolution and development,it has struggled with the internal community and the plateau environment over the years,and created a village form that cannot be copied,has historical categories,social significance and artistic value.It is a space product that human beings adapt to the environment.In the 21st century,the traditional villages are in the big environment of urbanization construction.Is it to keep the form consistent and harmonious and to stop,or to coexist and progress with social development?Therefore,this paper studies the traditional village morphology of Jiarong Tibetans in northwestern Sichuan from the perspective of environmental adaptability,in order to explore the adaptive model of coexistence between human and environment by exploring the relationship between village evolution and“environment”.This paper takes the village form as the research object,selects Zhibo Tibetan village as the case has carried on the environmental adaptability research.Based on Google Earth,the traditional villages of Jiarong Tibetans in northwestern Sichuan were positioned,and the layout maps of 101 villages in northwest Sichuan were mapped,and the age,nuclear density and morphological characteristics of the villages were developed;Through field research,establish a building information base for case villages.The combing analysis found that there are currently 101 traditional villages in northwest Sichuan:(1)the number before the Yuan Dynasty was 37(36.6%),the density value(0.971),and gradually decreased after the founding of the Ming and Qing Dynasties.The average density in northwestern Sichuan was 3.337./km~2;(2)Overall distribution characteristics:one heart(Danba County),two axes,four directions,five groups,multiple nodes,and distributed in a dendritic and pinnate shape along the water system;the most typical four types of morphological features:chain type There were45(44.6%),37 on the one side(56.9%),27 on the valley bank(48.3%),and 21 terraces and villages(45.7%).The investigation and analysis found that the shape of Zhibo Village is a“J”-shaped chain layout,which is a group-like block shape centered on the towers and temples.The intersections of the streets and lanes mainly have cross-shaped crosses,T-shaped,Y-shaped,and Z-shaped.The glyphs cross and their growth and evolution are mainly influenced by the complexity of the natural environment and the particularity of the national culture.In this paper,Arc GIS,SketchUp,Auto CAD and other software and bottom and topological analysis methods are used to analyze the overall pattern of straight waves,street roads,architectural forms,elevation,slope and aspect.The analysis results show that The elevation of the village is suitable for construction in the future(2501m-2522m),slope(9°-15°),and slope direction(south slope,west slope,northwest slope).Through the research on the shape of the village and the exploration of the factors of action,it is clear that the adaptive changes of the village formation stage,development stage and change stage are reflected in the three evolution states of originality,truth,abandonment and use,continuation and newness;the influencing factors are mainly organizational structure.The role of external policies,cultural practices,science and technology,economic production,religious beliefs and the integration and integration of various environmental factors.Based on the above research and analysis results,from the perspective of the contradiction between human settlements and limited space resources,based on the concept of environmental adaptability,build a village morphological gene map,analyze resource values and problems,and clarify the key aspects of village form protection;Summarize and refine the morphological organization pattern of the traditional villages in northwest Sichuan,and provide theoretical ideas for the subsequent development of the traditional villages of Jiarong Tibetans.
