Research On The Spatial Characteristics And Coupling Relationship Of Jinan Springs Rural Settlements

Rural settlement is an important spatial carrier of rural revitalization in the current era.Spring is a special cultural and natural heritage resource,and also an important spatial gene with regional characteristics.The study should focus on the rural settlement of spring.The rural settlement of spring water refers to the settlement of rural residents formed by the existence of spring water,which has a positive impact on the life and production of residents.Jinan has a large number of springs with different forms,and many mountains and hills.The diversity of spring space and topography is reflected in rural settlements,forming a unique rural settlement with different forms and characteristics.As an important resource in the early society,spring has an important influence on the site selection and spatial pattern of rural settlements.To a certain extent,it has created a unique spatial form of rural settlements and played an important role in the connection of three living spaces.With the influence of urban development and village activation,spring resources and spatial texture in spring rural settlements have suffered of destruction and decline.This thesis aims to excavate the regional spatial characteristics of spring rural settlements,and guide the protection and development of regional spring rural settlements.Based on the list of springs in Jinan City,51 springs outside the list are supplemented through research.A total of 359 springs and 242 rural settlements are obtained.The environment is studied from the aspects of ecology,production and life,and the spring waters with different distributions and types are introduced.This thesis sorts out the rural spring resources in Jinan City,summarizes the overall distribution characteristics of spring water from four aspects of geography,geomorphology,geology and land use,and explains the local distribution characteristics of spring water from plains,valleys and mountains.This thesis sorts out the spring-water rural settlements in Jinan,and analyzes the urban and rural distribution characteristics of spring-water settlements,the functional relationship between springs and villages,and the spatial relationship between springs and villages.The research focuses on three scales: region,section and village.The regional coupling research focuses on the spatial distribution system of spring rural settlements.Based on the connectivity analysis,the spatial distribution structure of ' one main,four vices and three cores' is summarized.According to the cluster analysis,the distribution aggregation of spring water is usually increased with the increase of altitude.The research on the coupling of sections focuses on the spatial organization of rural settlements in spring water.According to the index of spring water eccentricity,the quantitative relationship of spatial organization coupling of rural settlements in spring water is analyzed,and three typical rural settlement clusters in spring water are summarized,including mountain valley cluster,piedmont gully cluster and mountain valley cluster.The coupling study of village focuses on the location relationship between spring water and rural settlements.By counting the horizontal and vertical distances between spring water and settlement built-up areas,three spatial patterns of integration distribution,boundary distribution and alienation distribution of spring water and settlements are summarized.The spatial characteristics of rural settlements in spring water are also the characteristic zoning of geomorphologic environment and the characteristic classification of spatial patterns.The group analysis tool of Arc GIS is used to analyze the rural settlement of spring water,and11 characteristic zones are divided based on elevation landform.By analyzing the functions,scales,scenes and activities of springs,this thesis summarizes the spatial classification of settlements based on three ecological patterns and the feature classification of ' 3 categories + 9categories ' based on landscape patterns.According to the results of feature classification,the spatial distribution and quantitative relationship of different types of settlements and springs are studied,and their distribution characteristics under different feature partitions are analyzed.The protection and development of rural settlements establish a macro,meso and micro target system,adhere to the protection and development principles of regional coordination,zoning classification and system integrity,put forward the guiding path of protection and development from three aspects of spatial scale,spatial type and spatial circle,and put forward the strategies of cluster protection and coordinated development,zoning protection and classification development,circle protection and system development.Taking the mountain valley cluster in Jinyunchuan as an example,this thesis summarizes the current situation and problems of the cluster,and puts forward specific protection and development measures.
