Research On Spatial Gene Diversity Of Traditional Villages In Central Guizhou

In this paper,the theoretical basis of the spatial diversity and spatial gene diversity of traditional villages is studied and discussed,and the spatial diversity and spatial gene diversity of traditional villages in central guizhou are specifically determined.The spatial gene map of traditional villages is constructed,revealing the spatial characteristics of traditional villages in central guizhou,which has guiding significance for the protection and development of traditional villages and rural construction.The research results are as follows:(1)research results on the spatial diversity of traditional villages in central guizhou:(1)the spatial type of villages: based on the spatial scale,according to the spatial sequence of villages from outside to inside,the village space can be divided into three levels: natural environment space layer,village ontology space layer,architectural space and environmental space layer.The spatial layer of the village ontology mainly includes two elements: the overall spatial layout of the village and the space of streets and lanes.The architectural space and environmental space layer mainly include the architectural space elements such as residential buildings,public buildings,courtyard space,gate space,and 11 types of environmental space elements such as ancient tree space,well platform space,square space,street intersection space,tuen mun space,tuen mun wall space,and diaolou space,in total17 space types.(2)spatial type diversity: the spatial type diversity of 8 sample villages was determined,and the results showed that the spatial type richness and diversity levels of traditional villages in central guizhou were higher on the whole,and the richness and diversity levels showed a positive correlation.Differences between the individual,village and village degree of habitable environment condition of traffic(agricultural production conditions),the advantages and disadvantages,the village of dominant function(recuperat,tuen tuen,people),the intervention of ethnic village,village protection development planning elements such as,the higher the degree of the habitable environment,space type level,the higher richness and diversity;Thetraffic location condition affects the dominant function of the village to a certain extent.The more complex the function is,the higher the spatial type richness and diversity level will be.The more complex the ethnic composition,the higher the spatial type richness and diversity level.At the same time,the intervention of village protection and development planning plays a positive role in improving the richness and diversity of village space types.(2)research results on spatial gene diversity of traditional villages in central guizhou:(1)spatial gene identification: spatial genes of traditional villages in central guizhou were identified and extracted,and 138 types of spatial genes were identified by consensus,among which 17 types were located in the natural environment layer,14 types were located in the village ontology layer,and 107 types were located in the architectural space and environmental space layer.Found that form part of the roof of the houses,building materials,the door toward the basic form,doors and Windows,decorative elements appear the phenomenon of variation,mainly including flat roof form,the use of bricks and cement building materials,the door toward the no longer consider defense and is no longer based on householder birth horoscope and Angle to the front road layout,doors and Windows,the basic form of the circular,triangular arch,arc arch forms,such as the flat roof,brick,cement,the door is open,triangular arch,arc arch,round window,such as the seven new gene space.(2)the space: the genetic diversity of 8 samples village space genetic diversity were determined,the results show that the space of traditional village in guizhou gene richness and diversity are at a higher level,local-style dwelling houses building space space,toward the door space,square,street space,defensive space such as gene loci quantity,number of alleles is relatively abundant,gene richness and space diversity of village space contribution is bigger,this is the traditional village in central guizhou is similar to that of the overall condition of natural geographical environment,transportation,village development history background.Also because of the different villages of major ethnic groups,the location of the village layout,function characteristics of different people(recuperat,tuen mun,shang tuen,etc.),different levels of economic development,the traditional village protection development planning intervention time of different national traditional village list(included in different batches)gene number and caused the village space distribution characteristics.(3)results of the research on the construction of spatial gene map of traditional villages in central guizhou: the overall layout of villages highlights the two dominant factors of livability and defense,with the feature of "the mountain is not close to the backside,and the river is not close to the shore",presenting the spatial sequence pattern of water-tian-village-mountain ascending step by step with the natural mountain as the background.The layout of streets and lanes is mainly in the form of network and branches.The layout of the building and the shape of the facade from the whole to the details all reflect the characteristics of the central axis symmetry and reflect the Confucian cultural thought.Doors and Windows decoration is relatively complex,benevolent auspicious birds,flowers and plants,precious artifacts,geometric graphics and text language diversity,decorative elements such as character activity varied,enrich the building facade,over the years change,part of the building outside wall shot hole functions as the window,the villagers go out after school homecoming business building houses,building layout,great changes have taken place without the details of combination of Chinese and western style.
