Quantitative Study On Color Emotion Of Night Landscape In Central Area Of City

In the current urban night landscape lighting construction,the blind use of colors has caused many problems such as lack of human care and contradiction with the architectural character.How to reasonably control the night landscape lighting colors,the night landscape colors,to provide guidance for relevant professions,is an urgent problem to be solved in this research.First of all,this article clarifies the research purpose,research objects and research framework,based on previous literature research.Secondly,a qualitative and quantitative approach was conducted to investigate the current status of night landscape colors in the central area of Xi’an,Chongqing,Shanghai and etc.And then,this article analyzes the current situation of night landscape lighting and night landscape colors in the city center area,puts forward the current problems of night landscape colors in the city center area,and summarizes the types of night landscape lighting,lighting techniques and main color range of the city center,supplemented by related planning research.Third,the improved BIB-LCJ method is used to evaluate the night landscape beauty of the survey sample,and finally,according to the confidence interval,the research selects the excellent,good,and bad samples of different landscape scale night landscapes.Further,it validates the rationality of the survey classification,proves that the degree of beauty is greatly affected by the type of building and the way of lighting,and at the same time determines that the color is one of the important determinants of the quality of the night landscapery.Fourth,taking Chongqing as an example,the research sorts out the quantitative survey data,drawing on scientific research methods,and sums up the range and characteristics of the night landscape color and chromaticity of different landscape scales and different building types in the city center area,finally simultaneously reproduces the qualitative tendency color and quantitative measurement color under laboratory conditions.Fifth,under laboratory conditions,with the help of semantic analysis and factor analysis,the research evaluates the emotional preference of color simulation samples,uses SPSS to process the evaluation data and conducts a systematic study of the nighttime landscape color emotion from the aspects of research purpose,experimental preparation,experimental plan,and discussion of experimental results.And then,obtains the main components of the color sentiment evaluation of the night landscape landscape in the city center,and the color sentiment laws and prediction models of different landscape scales and different building types in the city center area.Finally,the research conclusions are systematically summarized,the problems and deficiencies in the research are explained,and prospects for future night color research are put forward.
