Research On Urban Street Landscape Color Design Under The Theory Of Environmental Perception

With the development of cities,urban streets also rise rapidly,but a large number of streets because of their ignorance of color problems bring people nervous,panic and other negative psychological emotions,destroy the regional features of urban streets,so that they lose the original collective city memory.Street is the main carrier of city color,and the people living in it actually live in this color relationship.Recently,urban color planning has been paid more attention,and urban street color has always been an important issue in the field of urban planning.Previous studies mainly focused on color psychology and color geography,and proposed planning principles or control methods and design points for street color.The research objects mainly focus on the color of historical and cultural streets or commercial pedestrian streets,ignoring the color shaping of ordinary urban streets.The research method focuses on quantitative research,which can provide relatively scientific basis to a large extent,but it also neglects the subjective psychology of personalized people because it is too rational.To solve the current research perspectives and research objects,research methods too rational status quo,based on the living street as the main research object,the surrounding people,the environment,and color,emphasized the perception and experience of people,to make up for the present stage in the theory of urban color design focusing on objective data,and the lack of subjective survey research gap.The aim is to use the theory of environmental perception to improve the overall image of the city,find the sense of belonging of citizens and build the overall order of streets.This paper selects Beiwei Road in Nanjing as the main research object,and adopts the methods of literature research,cognitive map,questionnaire and field research.Firstly,the knowledge of urban color planning,urban street color design and environmental perception theory at home and abroad are summarized.Secondly,the knowledge system of street color landscape under the guidance of environmental perception theory is sought.Explore the convergence of environmental perception theory and street color,and analyze the corresponding relationship.After that,field research and questionnaire survey were carried out on the street color of Beiwei Road in Nanjing.The problems in the current color situation of Beiwei Road were summarized by using semantic difference method,color analysis method and color and quantitative analysis method,so as to explore the design strategy of general urban streets.Finally,the color strategy suitable for Beiwei Road was proposed,and recommended chromatographic and matching schemes,effect display schemes and color space renderers were developed for each color carrier.Through the research and establishment of the theoretical framework of street color landscape design based on the theory of environmental perception,five design strategies applicable to general urban streets are explored,that is,clarifying the overall tone,using the environment to provide,integrating spatial order,expressing regional image,and paying attention to perceptual experience.At the same time,it puts forward the optimization strategy and color landscape design scheme for the color landscape design of Beiwei Road.In a word,using the theory of environmental perception is an effective way to explore the content and strategy of urban street color landscape design and shape it into a comfortable and positive space.
