| The natural distribution of China’s well salt resources is mainly concentrated in the eastern part of sichuan basin.Taking the salt field in the east and the south of sichuan as the origin,the salt economic belt formed from the east to the south,namely the sichuan salt ancient road.In the sichuan salt ancient road,the salt accumulation crowd finally formed the salt road ancient town,the salt road ancient town is the most complete salt road civilization witness.This paper,taking the representative salt ancient town on the east commercial road of sichuan to yunnan of sichuan salt road,those are Luoquan,Luocheng,Xianshi,Niufo as the objects,to do the research from the qualitative to the quantitative with the combination of the objective facts and subjective cognition on their space form.firstly,through a large amount of literature foundation and field visit,the formation and development of salt road ancient town are sorted out,and the spatial elements of salt road ancient town are summarized based on the theory of five elements of urban image.Then,this paper uses space syntax to analyze the internal logic of four salt ancient town space form form summarizes the objective advantages and limitations of town spatial structure,and do the comparison of the four ancient elements in syntactic characteristics of quantitative;Then,based on the theory of city image,using the method of cognitive map on Luoquan,Luocheng,Niufo,Xianshi to get the cognitive characteristics of users about the ancient town;Then,through the combination of the space syntax of quantitative research conclusion and the conclusion of cognitive map research,reference importance-performance analysis(IPA),to do the integration-recognition analysis method to analyze the above four ancient town,in order to make some exploratory efforts by use the specific case studies for general salt town protection and development.The main conclusions of this paper are as follows:(1)the Space element composition of salt road ancient town.The edges are mainly mountains and water,paths include streets and bridges,the landmarks are the characteristic building and the construction,the guild hall and the temple are the salt road important characteristic building,the nodes mainly include squares,wharves and wells,among whichwharves and wells are the characteristic nodes,the districts can be divided into three categories: residential,commercial and public life.(2)the Quantitative results of spatial form and spatial cognition of salt road ancient town.Through integrated nuclear analysis,salt road ancient town is mostly developed from commercial street,on intelligibility comparison result,Luocheng>Niufo>Xianshi>Luoquan,it can tell that the space which has more stable and regular network configuration has higher intelligibility,on recognition comparison result of Spatial element type,the landmark > the path > the node > the district > the edge,the landmark has the biggest influence.(3)Development and protection countermeasure of ancient town starting with space element.A four-quadrant model of integration and recognition was established,the elements in quadrantⅠshould consolidate advantages and carry forward the advantages,for the elements in quadrant Ⅱ take the measure of increasing publicity and guidance,for the elements in quadrant Ⅲ take low priority measure,for the elements in quadrantⅣ,implantation function stimulates potential.In addition,taking path and landmark as the most imortant status in the protection and development. |
