| In this paper,the spatial morphological structure,spatial type diversity,spatial gene diversity,spatial gene stability,spatial gene genetic characteristics,spatial gene diversity factors are studied in a more comprehensive way,revealing the spatial genetic characteristics of the traditional ancient towns in the traditional town,the exploration and inheritance,protection and development of traditional ancient towns is of great significance,the results of which are as follows:(1)The division of space type is based on Kevin Lynch’s spatial intention 5 elements,according to the main functions,characteristics and commonalities of each kind of space,the space is divided into detailed and summarized,the five elements are divided into 9 middle class,26 small categories and other spatial types;The projection of the unique natural area of the living customs in the middle of the city has created the characteristics of the diversity of traditional ancient town residents’ multi-faith and religious building space,the diversity of folk activities and the diversity of public space,the diversity of defensive space formed by military defense functions,the diversity of spatial organization of residential courtyards,etc.;Among them,the non-material environmental elements(economic,historical culture,society)and material environmental elements(architecture)which are greatly affected by man-made activities are the main factors affecting the spatial form of the traditional ancient towns in the central region of Guizhou,and the spatial morphological characteristics of the traditional ancient towns in the central region of Guizhou are obvious,the structure of the spatial form is complete and complex,the plane space is rich,the overall spatial structure of the ancient town is accessibility,permeability is relatively good,but the internal space is less controllable to the external space.The self-awareness of the space system is poor,and it is difficult to perceive the overall spatial structure characteristics from the local space,which reflects the better defensive characteristics of the ancient town.(2)The identification of spatial genes is divided into 3 scales to identify,respectively,small scale,mesoscale,large scale,corresponding spatial types are: building unit scale,building combination scale,road circumference scale to carry out detailed spatial gene identification and statistics,where the small scale hierarchy is divided into 1 Class space types,14 classes of gene bits,45 types of allethial genes,the mesoscale hierarchy is divided into 3 types of spatial types,13 types of gene bits,39 types of allegens;37 types of gene bits,91 types of allegance genes,analysis shows that there are differences between the traditional ancient town space individuals,but the overall spatial gene richness,diversity,uniformity index show a positive correlation,richness and diversity,uniformity When the degree is negative correlation,the diversity and uniformity are relatively high,its spatial structure and traditional style are in a relatively stable and balanced state,while the richness is higher,its spatial gene species are more abundant,the vitality of the ancient town remains good but the spatial structure and overall appearance are relatively unstable In addition,the genetic differences between the ancient towns are relatively small,Tianlong ancient town’s own genetic inheritance and protection are better,not too much by external factors and commercial factors,and Qingyan ancient town,the old state town by the external environment is relatively large.Therefore,in the development and protection of traditional ancient towns at the same time,but also to join the protection and development planning,pay attention to improve the richness of the traditional ancient town space type,the level of diversity.(3)The index system of spatial genetic influence factors in traditional ancient towns is divided into two levels,one of which is spatial pattern(0.1180),spatial structure(0.1579),stability(0.1012),cultural factors(0.2987),natural factors(0.1365),economic factors(0.2230),Social factors(0.1066),25 secondary indicators,to get the degree of correlation between the spatial genetic diversity and influence factors of traditional ancient towns in China,this set of indicators system can well reveal the traditional ancient towns in the maintenance of texture characteristics,the protection and development of other ethnic areas in Guizhou traditional ancient towns have a reference role.(4)This chapter,by accurately locating the historical and cultural value of the traditional ancient towns in China,clarifying the spatial characteristics of the traditional ancient towns,constructing a complete spatial gene system based on the "point-line-face-net-body" based on the theory of protecting and maintaining the diversity and integrity of the spatial genes,reveals the spatial genetic characteristics of the traditional ancient towns in the middle of the city,and is of great significance to the exploration and inheritance,protection and development of the traditional ancient towns in the middle of the city. |
