| With the development of highway construction and the improvement of living standards,people put forward higher requirements for the quality of highways,in addition to the necessary accessibility and safety needs,they should also have good environmental,ecological and cultural taste,and pay more attention to highway landscape design research.However,at present,highway landscape research generally focuses on the specific design strategies and schemes of specific highways,or only studies and discusses a single element,and lacks the research on the theoretical methods of highway landscape design systems.Based on the above background,this paper introduces the schema language theory,combines the characteristics of highway dynamics,stripiness and other characteristics,as well as environmental ecology and humanistic needs,and constructs a highway landscape schema language system to enrich the theory and technology of highway landscape design.Firstly,starting from the linguistic logic,spatial logic and schema characteristics of the landscape,the connotation of the schema language is analyzed,the essential characteristics of the schema language are proposed,including the deconstruction and reorganization,scale and diversity of the landscape,and the adaptability of the schema language theory in the field of highway landscape is discussed.Secondly,by extracting typical highway landscape patterns with good environment,ecology and humanistic atmosphere,a common vocabulary system of highway landscape is established,a total of 20 "words",10 "words" and 8 "phrases" are listed,and the physical elements and morphological elements of the landscape are started,combined with the driver’s visual psychological feelings to analyze the characteristic attributes and semantic presentation of each vocabulary;based on the narrative of the landscape and the environment,ecology and humanistic needs,the schematic vocabulary should be selected and applied in accordance with the principles of focusing on the theme,adapting to local conditions and paying attention to humanities.Thirdly,based on the compounding of highway landscape space,the formation logic of "words" and "phrases" in the vocabulary is analyzed from the perspectives of basic lexical and compound lexical,and the four basic lexical and five compound lexical methods are analyzed in combination with examples,and the influence of each logical relationship on semantic and semantic expression is explored from the perspective of driver vision and psychology.Then,through the example analysis,the mechanism of the spatial syntactic relationship of the highway landscape and the principle of its selection and application are analyzed,and the practical application method of the spatial syntax is further proposed by borrowing the transformation generation law from the syntactic structure;through the case analysis,the sentence group needs to be organized according to the context,and the key factors affecting the landscape context are proposed from the perspective of the characteristics of the highway landscape,which are the overall relationship of the landscape elements and the prominent features in the spatial pattern,and the organizational method of the sentence group is analyzed in summary.Finally,the examples of highway engineering in Tibetan areas are selected to verify the adaptability of schema language in highway landscape design,and to propose a universal technical route for highway landscape design based on schema language.In summary,based on the pattern language theory,this paper constructs the highway landscape pattern language system by analyzing the nested structure,process mechanism and logical context of highway landscape elements and landscape space,proposes a universal design method for highway landscape,enriches and expands the theory of highway landscape design,and has reference value for the practice of highway landscape engineering.This paper constructs the pattern language system of highway landscape pattern by analyzing the nested structure,process mechanism and logical context of highway landscape elements and landscape space,proposes the universal design method of highway landscape,and enriches and expands the theory of highway landscape design. |
