The Research On Spatial Form Map Of Traditional Villages In Western Sichuan Area

The natural constraints of high altitude and mountainous areas in western Sichuan and the cultural influences of Tibetan,Qiang,Han,Hui and other multi-ethnic groups gather together to consist of different forms of traditional village's human settlements.At the same time,the Zang-Yi Corridor,Tea-Horse ancient road and other linear corridors accelerate the flow of the region,promote the communication and integration of various nationalities,and further affect the development of the spatial form of villages.Currently with the rapid development of urbanization,traditional villages is facing the impact and destruction in the region.The primary task of the current protection and development of traditional village is to establish a space form investigation and cognition which see characteristics identification as the core,is maintain the cultural self-consciousness of regional characteristic culture,is also important to found and construct the habitat gene-bank in southwest area.With the western Sichuan area as the research area,67 national-level traditional villages in the first four batches were selected as the research objects.With the help of village archives,satellite maps,topographic maps,planning maps and relevant historical literatures,the basic database of traditional villages in the western Sichuan area was established based on field investigation and plotting.This paper studies and analyzes the characteristics of natural environment and cultural environment in western Sichuan,as well as the basic characteristics of traditional villages in western Sichuan,such as quantity,scale,age,nationality,spatial distribution and spatial-temporal evolution,and determines the cultural regions of western Sichuan based on the combination of organizational evolution and ethnic migration.On this basis,and focus on the traditional village space form of spectrum analysis method which form "partition-fractal-classification",the detailed construction of village location and configuration,morphology and structure,space structure and organization,architectural layout and form to build the four dimensions of spatial form map of the traditional villages,Through comparison of different types,partition,describe three features the similarity,heterogeneity and connection.And the genealogy is summarized from three aspects: Genealogy table,genealogy chart and general characteristics.This paper mainly includes three parts:Firstly,which establishes the research foundation and the theoretical framework of this paper.Clarify the research background and significance,and determine the scope and object of this study.According to the relevant research on spatial morphology,the spatial morphology of traditional villages is mainly composed of "four dimensions".At the same time,influenced by multi culture,traditional villages form the "three characteristics".Combined with the theory and method of atlas,the theoretical framework of the spatial morphology of traditional villages is constructed from the following three aspects: content,technical framework and element level.Secondly,establish cultural region about western Sichuan with the multi-factor comprehensive.The western Sichuan area is complicated.With the concept of cultural circle,this paper analyzes the regional environmental characteristics and the basic characteristics of traditional villages in western Sichuan,and establishes a comprehensive cultural region by combining the elements of organizational evolution and ethnic migration.Thirdly,which establishes the four spatial form map of traditional villages in western Sichuan through classification,comparison and summary.1.the spatial forms of each dimension are classified,by specific standards,such as basic characteristic,pattern diagram.2.based on cultural region,this paper compares the spatial forms of the four cultural regions in different dimensions,and defines the main types,overall characteristics and formation mechanism of the cultural regions,Besides it describes the characteristics and causes of the formation of typical types.3.type comparison: compare and analyze the classification types of each dimension,summarize the quantity,distribution,characteristics and formation reasons of each type;4.all types of villages were counted to establish the table of the spatial form map.The type information of villages was superimposed with the spatial information of villages,and visual expression was formed with the help of GIS to form the spatial form map chart of all dimensions,and summarize the spatial distribution characteristics,The spatial pattern of four dimensions of traditional villages in Western Sichuan was formed.This study expands the regional category of traditional village research,and combines the cultural region theory to put forward the regional cognition method of complex terrain and multi-ethnic cultural region,that is,the geographical region with similar cultural attributes and characteristics is defined as the research unit.In view of the diversity and complexity of the spatial forms of villages,a research system of classification comparison and division comparison is established based on classification and combined with cultural region.Thus the genealogy expression based on the chart is formed with graph theory.This study explores the spatial form cognition method of traditional villages in the region,which is of practical guiding significance for the protection and development of traditional villages in the region,and also enriches the theories and methods of rural spatial form research in China.
