Research On The Overall Association Mode Of Landscaping And Cultural Space Structure In Fenghuang Ancient Town Based On Visual Domain Evaluation

Historic towns of china are important carriers of Chinese traditional civilization.The pattern of cultural space construction and landscape echo overall contains unique construction experience and connotation.Visual is important information source of human perception of outer space,people through visual perception initiative transformation and construction of the objective material world,and in the construction of space reflect the cognitive nature philosophy connotation,in the space of Chinese traditional ancient town design,its "back mountain surface water" the concept of "looking towards the mountains" contains the visual space of the typical logic design,through the visual perception,It can reproduce the spatial interaction between the historical town and the landscape in the spatial and temporal dimension,and summarize the historical construction experience,which has important research value and reference significance for excavating the characteristics of the ancient town and inheriting the context of the ancient town.Fenghuang Ancient Town in Zhashui County,Shaanxi Province has a long history of development and construction since the Tang Dynasty.It has condensed the most intelligent construction experience in the aspects of planning and location selection,spatial layout and design of integration with nature.This paper focuses on the visual landscape of landscape and human space in Fenghuang ancient Town.Based on human perception as the basic starting point,GIS and other visual analysis methods are used to analyze the elements of landscape and human space in the ancient town.Through the four aspects of human habitation-natural landscape correlation,cultural space-natural landscape correlation,human habitation-cultural space correlation,and cultural space-cultural space correlation,the quantitative index measurement system of the overall correlation of landscape and human space is constructed,and the key space visual domain identification is carried out from the current landscape aesthetics and regional cultural visual landscape research.The study found that the points with a high degree of visible landscape in the human space have the characteristics of cultural space.The range of visible landscape is concentrated in the Shechuan River and the mountain on both sides of the Zaohe Ditch,showing a "T" shaped spatial layout,and the line of sight develops outward in some road space nodes,and has a clear directionality of the mountain.For the humanistic space points,the humanistic space points with a high degree of visual mountain include Kangjia courtyard,Mengjia courtyard and Shengfa Inn.These humanistic space points form a visual association group with other elements,and religious sacrifice space points respectively form a landscape visual system.Based on the characteristics of the visual environment,it finally summarizes the overall pattern of(1)looking at the mountain by the water,surrounded by mountains and rivers,(2)multi-dimensional connection,association pattern of group perception,(3)four domains of defense,security defense mode of high walled off,(4)multi-directional overlooking,different mountain views toward the mode,(5)one side of the look,five overall association pattern types of art mode of shaping unique scenery.And put forward the optimization strategy of landscape humanistic spatial pattern of Fenghuang Ancient Town based on visibility.Through this study,the interactive relationship between natural landscape and human space can be scientifically and quantitatively recognized at the regional scale,which echoes the needs of natural landscape protection in the modern context,excavates the experience of historical visual landscape construction,inherits the wisdom of landscape construction,and establishes a set of operable measurement index system.In order to guide the historical pattern and visual space construction of ancient towns,It provides reference and basis for the protection of historical and cultural famous towns,pattern recognition and protection of ancient towns and related evaluation.
