Study On The Spatial Morphological Characteristics Of Rural Settlements In Xihaigu Area Based On Spatial Syntax

The Xihaigu region in southern Ningxia is one of the typical ecologically fragile regions in China.With the continuous acceleration of economic development and urbanization,the overall scale of rural settlements continues to expand,their functions continue to gather,and their policy demands continue to improve,leading to the increasing complexity of the rural spatial system and the lack of sufficient resistance to various disturbances in spatial forms.Therefore,in the context of rural revitalization,professional analysis and summary of the spatial characteristics of rural settlements in this region can help to focus on many rural spatial forms represented by Xihaigu,providing comprehensive scientific guidance for their healthy development and rational construction.On the basis of abundant obvious representations represented by buildings and streets,this article uses spatial syntax analysis method to quantitatively analyze the spatial form of rural settlements in Xihaigu,taking space itself as the entry point,and summarizes its implicit representations.The paper is based on the theoretical connotation of the spatial form of rural settlements,combined with the characteristics of spatial syntax research,using a combination of qualitative and quantitative research methods.From the three levels of overall spatial form,linear street and lane space,and point public space,the syntactic deconstruction of the spatial form of rural settlements in Pengyang County is carried out,and its spatial characteristics are summarized.The research content of this article includes:Firstly,by analyzing the theoretical connotation of the spatial form of rural settlements and studying the specific analysis methods of spatial syntax,the advantages of spatial syntax in studying rural settlements are explained,and a research approach based on spatial syntax for rural settlement spatial form is constructed.The research hierarchy of rural settlement spatial form based on spatial syntax is divided.Secondly,based on the on-site investigation and summary of the behavior patterns of local villagers in Pengyang County,Xihaigu,qualitative and quantitative analysis was conducted on the spatial characteristics of the village from three levels: overall spatial form,linear street and lane space,and point public space.(1)The axis analysis method of spatial syntax was used to analyze the comprehensibility,integration,depth,connectivity,and other indicators,Conduct a comparative study on the differences in spatial cognition and permeability of villages in different terrains.Based on the topological axis map and syntactic variable parameters,the syntactic structure and common differences of the overall spatial form of rural settlements in the Xihaigu area are summarized,which include similarity in village site selection,similarity in village spatial structure rules,diversity in plane form,and a certain correlation between the spatial recognition of rural settlements in Xihaigu and terrain features,The spatial cognition level of plateau type villages is higher than that of river valley and channel type villages,and better than that of mountainous and hilly type villages The study of linear street and alley space first qualitatively describes the interface and plane of the street and alley,then calculates the integration degree,connection value,and average depth value of the street and alley axis model,and then constructs a field of view model for the main street of the sample village to calculate the integration degree,depth value,and angle turning degree of the line of sight,and then summarizes the spatial characteristics of the street and alley: the form of the street and alley enclosure is different,and the plane form of the street and alley is often diverse The core characteristics of street and lane traffic are analyzed using SPSS to obtain the clustering characteristics of street and lane space and the line of sight characteristics of street space For the analysis of public space,based on the concept of spatial topology in spatial syntax,this paper analyzes the structural types of public space system of rural settlements,which are mainly divided into three types: central structure,network structure,and serial structure.Then,through the separation of the core of integration,it studies the corresponding laws of public space distribution and reachability of rural settlements.Select different types of public points for visual analysis,and explain and summarize the morphological characteristics of public spaces.Spatial syntax is of great significance for the optimization,updating,and sustainable development of rural settlement spatial morphology.Therefore,further exploration of the application value of spatial syntax analysis in rural settlements is proposed,and optimization strategies for rural settlements in the Xihaigu area are proposed.Propose optimization and update strategies from the overall spatial level,street and alley spatial level,and public spatial level,respectively,for the development of zoning planning based on depth values at the overall spatial level,and for the planning,construction,and optimization of new villages under visual analysis;At the level of streets and alleys,control the village structure with reference to the degree of integration,and optimize the street and alley network with comprehensibility as the guide;At the level of public space,based on the degree of integration,line of sight penetration and field of view aggregation coefficient,the location of public space is optimized,the spatial visual environment is strengthened and the crowd activity route is guided.
