Spatial Optimization Of Suburban Integrated Rural Communities In Changsha-Zhuzhou-Xiangtan Under Symbiosis Theory

With the deepening and steady progress of the rural revitalization strategy,China’s rural-urban relationship has undergone great changes and has entered a new era of integrated urban-rural development.As an important area to balance the dual relationship between urban and rural areas,suburban integrated villages not only have the advantages of natural resources to develop into urban backyard gardens,but also have the ability to transform into cities,which is an important area to realize the rural revitalization strategy.However,at present,due to the multiple changes in natural environment,population structure,land use,industrial structure and other aspects,the contradiction between production,living and ecological space in such rural areas is becoming more and more acute.In the face of such a complex and severe situation,how to optimize the spatial internal structure of suburban integrated rural communities and adapt to the impact of external environment has become an urgent problem to be solved.Based on this,this paper introduces the "symbiosis theory" to guide the optimization of the rural community space in suburban integration of ChangshaZhuzhou-Xiangtan,hoping to achieve a stable,efficient and mutually promoting state and promote the urban-rural integration development.T The research content of this paper includes five parts:The first chapter takes the research background and significance as the starting point,clarifies the definitions of the concepts related to this research,and extracts the research structure of the thesis by analyzing the general situation of domestic and foreign research.The second chapter is related research of symbiosis theory.This chapter firstly summarizes symbiosis theory from its origin and extension.Secondly,the essence and connotation of symbiosis theory are deeply analyzed.Finally,by analyzing the development of symbiosis theory in the field of architectural planning,the enlightenment of symbiosis theory on the spatial optimization of suburban integrated rural communities is obtained,which provides a strong theoretical support for the introduction of symbiosis theory and the construction of method system in the following paper.The third chapter first summarizes the basic characteristics of changsha-ZhuzhouXiangtan suburban integration villages;Secondly,based on the data collation of field research and questionnaire survey,it is concluded that there are three problems of insufficient coordination,weak connection and poor integrity in the productionecological space at present.Finally,by summarizing and sorting out the problems,the paper reveals the new demand for the spatial development of suburban integrated rural communities--symbiosis,which provides a realistic basis for the extension of symbiosis theory and the proposal of symbiosis strategy below.The fourth chapter demonstrates the symbiosis theory is introduced into suburban fusion class first the feasibility of the rural community,then clear rural community space symbiosis connotation and composition of symbiotic system,through the analysis of the symbiosis mechanism,put forward from the vertical function optimization,horizontal communication,the overall environment to coordinate the three dimensions to achieve the ideal state of community space.The fifth chapter,guided by problems and demands,uses symbiosis law to respond to the problems of "production-living-space" one by one.Aiming at the problem of insufficient coordination,the strategy of integration and reconstruction of symbiotic units was proposed,that is,function optimization of production-production space;Aiming at the problem of weak connection,the strategy of activation design of symbiotic interface was proposed,that is,to strengthen the communication and connection of production-living-ecological space from the spatial pattern of streets and lanes,connection efficiency and diversified design.In view of the problem of poor integrity,the strategy of positive reinforcement of symbiotic environment is put forward,that is,the overall coordination of production-ecological space from the aspects of culture,society and policy.To sum up,the optimization of suburban integrated rural community space is a complex process.Based on the theory of "symbiosis" as the breakthrough point,from the theoretical knowledge to the method of system building to strategy is put forward,the whole process step by step a progressive,changzhutan urban integration for rural community space optimization provides a new Angle of view and build a set of feasible path of practice,hoping to provide theoretical reference for the future fusion class suburb rural construction and practice of using for reference.
