| At present,the construction of China’s transportation infrastructure is in a stage of rapid development.Due to the vast area of mountainous areas in China,mountain roads occupy a large proportion of the transportation system.At the same time,as a linear space,highway passes through a region or even several regions.It is not only the "aorta" that promotes social and economic development,but also the "main window" for displaying the image of the local area and giving visitors the "first impression".At this stage,there is a lack of systematic discussion on the modeling of mountain road landscape,especially the expression of cultural landscape design.To this end,from the perspective of regional cultural expression,this article creates a mountain road landscape with rich regional cultural characteristics,and explores the design expression methods of regional culture in mountain roads.First,on the basis of the definition of the concept,the composition and characteristics of the mountain road landscape and regional culture are explained,and the relationship between the regional culture and the mountain road is summarized,and the expression process and elements of the regional culture in the road landscape are proposed in combination with related theories: Information about regional culture(things),expressing carriers of highway culture(obejects),and recipients of highway landscapes(people).Secondly,according to the process of transmitting information to the carrier,people perceive information through the carrier,and summarize the method of regional cultural expression in the mountain highway landscape from five aspects: the choice of regional culture,cultural expression carrier,expression form,expression technique and status of viewing from mountain road users.This paper summarized the constituent elements of regional culture,and proposed methods and principles for refining the theme of regional cultural expression,and selected representative regional cultures as the content of the message.The independent elements are selected from the composition of the mountain road landscape as the cultural expression carrier in the mountain road landscape.This paper determined the form of cultural expression: colors,words,shapes,patterns,materials;organize and summarize the methods of cultural expression: representation,metaphor,symbolism,abstraction,retention,and established the connection between information and carrier in the form and technique of landscape.According to the perceptual characteristics from viewers of different viewing states of the road landscape,the pertinent cultural expression design is made: in terms of dynamic viewing,the recognizability of cultural expression is improved from the scale and color of cultural expression,and length of the shortest cultural landscape interface is determined,as well as the reasonable scale of cultural structures on the side of the road.Create heterogeneous cultural landscapes and series of cultural landscapes to enhance the memory of cultural expression.In terms of static viewing,cultural expression design is made from three aspects: clarifying cultural themes,expressing culture in an interactive way,and integrating into industrial culture.Finally,this paper investigated the Airport Road in Fengjie County,Chongqing City,analyzed and summarized the elements of Fengjie regional culture,and extracted representative regional culture.According to the actual situation of Fengjie Airport Road,the expression carriers of Fengjie Airport Road are classified and summarized.The cultural expression forms and techniques are used to design the cultural expression in the dynamic and static state according to the perception characteristics of the viewers in the dynamic and static state.It summarizes and reflects on the overall thesis research,and puts forward prospects for the deficiencies of this thesis. |
