Analysis Of The Spatial Context And The Evaluation System Of The Metropolitan Area In Xi’an During The Sui And Tang Dynasties

Since the 1990 s,the urban landscape under the influence of globalization is faced with the situation of diversification,and the urban construction,which is characterized by the expansion of city scale,is also eroding the historical landscape and environment of Chinese traditional cities.City side "of the scene.In the face of the disappearance of urban cultural characteristics,in the context of heritage and revival of traditional culture,to explore the contemporary city of the historical context of protection theory is particularly important.Xi’an,the capital of ancient China,carries the traditional history and culture of China for thousands of years.Based on the theory of urban space and context unit,this paper analyzes the evolution of urban spatial context elements in Xi’an from the aspects of dominance and recessiveness.At the same time,the author analyzes the evolution of urban space context elements of Xi’an City,including biogeology,urban morphology,Xi’an 710049,China)Based on the basic theory of architectural typology,this paper evaluates the value of spatial context in the capital city of Xi’an by means of analytic hierarchy process and environmental perceptual model under the basis of identification and construction of urban spatial units in Xi’an.Its main contents include:An Analysis of the Cultural Elements in the Capital Region of the Sui and Tang Dynasties in Xi’an.Based on the historical development stage of Xi’an city,this paper analyzes the three aspects of the spatial environment,urban built environment,social economy and culture of the capital city of Xi’an in the Sui and Tang Dynasties,and discusses the social and economic context by gray relational analysis Elements and built environment context elements of the internal logic between the relationship.Identification and Mapping of Spatial Genes in the Capital Region of Xi’an Sui and Tang Dynasties.This paper introduces the basic concepts and methods of biological genetics,urban morphology and architectural typology,and discusses the spatial pattern of spatial units in the capital city of Xi’an from the aspects of boundary,region and related area.Then,from the perspective of genes of space context unit,the urban spatial unit type under macroscopic and microcosmic levels is divided into two parts,and the spatial and temporal unit map of the capital city of Xi’an Sui and Tang Dynasties is constructed.An Evaluation System and Methodology of the Regional Space Context of the Capital of the Sui and Tang Dynasties.Based on Husserl’s theory of phenomenological perception,this paper discusses the characteristics and modes of Chinese urban context.Based on the regional spatial units of the capital city of Xi’an and Sui and Tang Dynasties,through the analytic hierarchy process,the environmental perception model is the essential and integral value of space culture.And finally form an integrated self-optimization evaluation system of the evaluation-feedback-reevaluation working mechanism.This paper is a sub item of the National Natural Science Foundation of China(51578436): the evolution mechanism and inheritance strategy of historical cities and towns in the "Changan Tianshan Mountain" section of the Silk Road Economic Belt...
