Evaluation Of Rural Development Level And Classification Of Rural Areas In The Context Of Land And Space Planning

The division of village types is an inevitable requirement of rural revitalization strategy and land spatial planning.This study takes Wannian County as the research object,and conducts a study on the classification and optimization of village types based on the level of natural villages.This article first builds a rural development static evaluation system from the four aspects of location,human resources,land resources and economic factors based on the topography and zoning,and builds rural development from the population scale of living space,industrial level,and public service level.Dynamic evaluation system.The projection pursuit model based on genetic algorithm and the mathematical model of gravity model are used to comprehensively evaluate the rural development level of Wannian County and the cluster analysis method is used to divide the village types.The main content of this study is divided into seven chapters:Chapter One Introduction.From the background of rural decline,national land spatial planning,rural revitalization,and actual social needs of Wannian County,the research background and significance of this study are clarified,and the research purpose,research content,and technical route are proposed.Chapter II,related concepts,domestic and foreign research progress and theoretical basis.It briefly expounds the concepts of villages and towns,and reviews the current status of rural development research and the division of village types.Finally,a basic theoretical explanation of typology and central theory is given.The third chapter is the development status of villages in Wannian County.First,the geographical location,administrative status,natural conditions,social economy,transportation network,population and land use of Wannian County are described in an overview.Secondly,it briefly introduces the data sources and makes a basic statistic on the data obtained from the questionnaire.It mainly includes the land resource situation of the village,population,livelihood resources and industrial foundation,economic situation,cultural resources and infrastructure,and agricultural and social development.Finally,the characteristics of rural spatial differentiation are analyzed from topography,water system,traffic,slope,and economic and agricultural level.The fourth chapter is the comprehensive evaluation of village development in Wannian County.First,describe the idea of index construction and construct index selection from static and dynamic aspects,and explain the reasons for the selection.Second,it introduces the construction and improvement of projection pursuit model and gravity model based on genetic algorithm and explains the principle of cluster analysis.Third,based on genetic algorithm projection pursuit model and gravitational model to evaluate the rural development level and gravitational value analysis under different location conditions.The fifth chapter is the division of village types in Wannian County.Describes the basic idea of village type division,and makes a basic judgment and definition of the village type division standard,and on this basis,the basic data statistics of different types of villages.Chapter VI,Wannian County Rural Optimization.Mainly through the town and village node system,optimizing the shape of settlements,and proposing different future development directions for specific types of villages,and simulating their future village development directions with gravity models.Taking Huyun Township in Wannian County as a case,analyze the existing problems and propose specific optimization measures.Chapter VII,conclusions and prospects.Summarize the main conclusions,point out the deficiencies in the research and look forward to further research in the future.research shows:(1)The extensive use of rural land in Wannian County exists.(2)The distribution of villages in Wannian County has the characteristics of main roads,water systems and slope trends.As the distance from the main road and the water system increases,the slope increases and the number of villages decreases.(3)The rural development level of Wannian County has obvious differences.Among them,the rural areas in the plains are mostly distributed at the general level and higher levels.As the landform changes,the distribution of rural development levels also changes from the general level to the comparative level.High-level rural to low-level and ordinary level.(4)By combining the two clustering analyses of gravity,urban-rural distance,and human resource factors,the five categories of suburban-integrated villages,original villages,characteristic protection-type villages,agglomeration-elevation villages,and demolition and demolition villages are finally divided into five categories..Among them,the number ranking is distributed according to the size of agglomeration and promotion type,suburban integration type,demolition and merger type,original type and special protection type.(5)The optimization ideas are proposed from three aspects: the spatial layout of town and village nodes,residential areas and the optimization of different types of villages.The case study of Huyun Township in Wannian County was optimized to analyze its existing problems.Huyun Township has the problems of unreasonable village node system,low public service level,unreasonable population size,and high construction land per capita.Finally,this paper proposes specific optimization measures from the three aspects of the village system,the distribution of the central village and the population size.(6)Use the gravity model to simulate the connection degree of each village within the township and township,and take the direction of the maximum gravity value as the development direction of the future village development,and on this basis,propose the future development optimization directions and suggestions under different types of villages.
