Study On The Suitability Allocation Of Rural Public Service Facilities In Dayi County From The Perspective Of Life Circle

Under the policy background of rural revitalization strategy,"agriculture,rural areas and farmers",as the focus of priority development,have been paid great attention to,but the allocation content and construction level of rural public service facilities are low for a long time,and the malpractice of the allocation mode of "graded supporting-thousand people index" appears,which neglects the uniqueness of rural areas,resulting in the difficulty in meeting villagers’ needs.Therefore,the reconstruction of scientific and rational rural public service allocation system is an important issue in rural planning and construction.Based on the perspective of life circle,this paper discusses the demarcation logic of rural life circle,discusses the relationship between the spatial organization and decision-making results of public service facilities in rural life circle,and puts forward the division principle of hierarchical demarcation and classified control,so as to combine residential space unit with production space unit in a reasonable and scientific circle system and orderly organize the flow of resources and the order of facilities supply.The main chapters of this paper are composed of the following four parts:The first part is the basic research,including the theoretical content and practical experience of public service facilities layout optimization,multi-supply model,facilities post-use evaluation,facilities configuration cases.The second part mainly discusses the rural public service facilities allocation from the perspective of life circle,and creatively puts forward the framework of rural life circle public service facilities allocation and the division method of rural life circle layer system.The third part takes Dayi County village as the empirical object,defines the level of public service facilities allocation,constructs the framework of rural life circle in Dayi County,and delimits three levels and six types of rural life circles in Dayi County from three dimensions: settlement space,integration development of in.The fourth part combines the development planning and basic conditions of Dayi County to optimize the construction standards of education,health care,culture and sports,social welfare facilities.At the same time,Dayi County for the classification of rural areas to provide the corresponding business services,tourism reception,agricultural production facilities,to achieve differential configuration,suitability for use.In general,this paper further makes theoretical identification and strategic construction on the spatial organization decision-making mechanism and suitability allocation framework of rural life circle,and explores the chimeric relationship between the delimitation logic of life circle and the supply factors of rural public service facilities.The rural life circle system of Dayi County is completed by using GIS spatial analysis,AHP analysis method and POI data analysis,so as to provide reference experience for rural construction.
