Research On The Coupling Design Strategy Of The "Three Living Spaces" In Dong Ethnic Settlements In Northern Guangxi

In the report of the 19 th National Congress of the Communist Party of China,it was mentioned that the sustainable and coordinated development of rural areas is the means of rural revitalization,and the rural space should focus on establishing the coupling coordination of "production-life-ecology" space.The report at the 20 th National Congress once again emphasized the need to comprehensively promote rural revitalization and comprehensively build a modern socialist country.With the deepening of urbanization,most of the young people in rural areas are going out to work,resulting in an increase of aging and younger population in some rural areas,resulting in the disappearance of vitality and power of living space.The lack of labor force will also make the efficiency of production space low,and the pressure of production and living space will cause problems in the function of ecological space.Therefore,when discussing how to carry out rural revitalization,we can start from the coupling degree and coordination degree of "three kinds of space",analyze the characteristic form,characteristic reasons and influencing factors of "three kinds of space" one by one,and analyze the feasibility of spatial coupling between the three kinds of space by analyzing the evolution process and coupling coordination degree of the three kinds of space and data visualization,so as to coordinate the development of the Dong people’s three kinds of space.The coupling design of "three-life space" is conducive to promoting the development of local space and ultimately achieving harmony and prosperity.The research object of this paper is mainly the Dong settlement of Sanjiang,the largest Dong autonomous county in Guangxi Guibei region.In this paper,"ecological space" as the entry point and spatial coupling as the means,analyzed the pattern characteristics and texture characteristics of the ecological space of the Dong people’s settlements,and based on Arcgis method,conducted data analysis and spatial coupling degree analysis of the evolution trend of the local ecological space,proposed the path in line with the local development,integrated and optimized the functional co-optimization of the ecological space,and enriched the development means.The construction basis is put forward to provide ideas for the future development of Dong people in Sanjiang.This paper is divided into six chapters,three parts.The first two chapters are the first part,which introduces the research background,purpose and significance,research status and scope of this project,explains the concept of the research means,theoretical basis and research object,explores the status quo,development and evolution forms of "three-life space" of the Dong people,and categorises the research modes of spatial coupling design.The second part is the third chapter and the fourth chapter.The third chapter focuses on the feasibility of studying the base coupling,analyzes the pattern characteristics of the local "three-life space",and obtains the characteristics of centrality,hierarchy and integration.At the same time,the case analysis is targeted to provide the feasibility basis for the subsequent spatial coupling mechanism.After realizing the feasibility of the project,combining with the design principles and strategies,the design method is given to provide more solid theoretical support for the project research.The last part is the fifth chapter of the design practice,this part is devoted to the theory into practice,through the actual design case coupling design.
