Research On The Evaluation And Optimization Strategy Of Huizhou Traditional Village Lightscape ——Take Three Villages In Qimen County For Example

In recent years,soundscape,lightscape,landscape emerging design theory such as updating and transformation of public and historical space design to produce a more and more important,the influence of the huizhou traditional village as an important part of our country farming culture heritage,as well as history and culture,living environment in areas such as hot topic,has been a lack of attention to this.Generally speaking,the present stage of lightscape design research focuses more on artificial light,mainly lighting design,which violates the historical and original spirit connotation of huizhou traditional villages.Therefore,this paper takes the natural lightscape of huizhou traditional villages as the research object,focusing on the change of natural lightscape between dusk and dusk.The research is carried out in three stages: investigation,evaluation and optimization.The detailed work includes the following three parts:Field research.Combined with AHP,the subjective and objective lightscape data of different time periods（different illumination conditions）in the study area were investigated in detail.The results show that :（1）the brightness of the village at noon is about 13% higher than that in the morning,and the brightness in the evening is about 3% higher than that in the morning.（2）The overall color of the village is not bright.The pixel values of the red-green channel in the photo are mainly distributed between-10 and 10,while the pixel values of the blue and yellow channels are between-30 and 30,and the poles are almost 0.The colors of the village are mainly green,gray and white,and many colors are mixed but not prominent.At the same time,there are significant differences in the color of morning,noon and evening in the village,with cyan,gray and white as the main color in the morning.In the evening to coffee,light yellow and warm gray;Noon gray,blue,green and other multicolor interweave,no particularly obvious dominant tone.Subjective evaluation.The subjective evaluation of village lightscape is quantified from two levels of regional whole and single element.The study showed that :（1）sunset light was more favorable to people,while twilight light was less favorable,but still stronger than daytime overall.（2）Blue stones and tiles are popular early in the morning,while warm colors of wood and pebbles work better in the evening.（3）Only in the morning and evening when the sun slanted,respondents were more able to perceive fragmentary lightscape elements,while in the noon when the sun shone vertically,people would weaken their perception of material,pay more attention to large-scale elements,and tend to judge from the perspective of form.（4）The subjective evaluation of lightscape elements has local coupling effect,and the combination and collocation of some specific lightscape elements can produce obvious gain effect on the subjective evaluation of lightscape.Analysis of influencing factors.This paper discusses the influencing factors of subjective evaluation of village lightscape from four aspects: brightness,color,element and coupling.The research shows that :（1）brightness will affect the subjective evaluation of the lightscape,and 50-60 is the most appropriate range.（2）The lightscape of the region with good subjective evaluation of the sample villages is generally shown as "warm color",and the color composition is rich in blue and yellow dimension,and the distribution is relatively uniform;In the regions with poor subjective evaluation,the tendency of red and green is not obvious,while the tendency of blue and yellow is obvious.There is no dominant tone,showing a mixed state of various colors with black,white and gray as the keynote.（3）The impact（explanation）rates of morning,noon and evening lightscape factors on regional evaluation were 43.8%,38% and 51%,respectively.The impact of each factor on overall evaluation was also different.（4）Coupling effect of large probability evaluation exists between lightscape elements.Optimization strategy.According to the research,village lightscape optimization should follow the principles of "regional","suitability" and "hierarchy",and be organized hierarchically and based on subjective evaluation.Macroscopic optimization strategy is mainly guided,including brightness guidance,color guidance,element guidance and coupling guidance;The micro optimization strategy focuses on local construction,including the coordination of lightscape key and lightscape organization of point,line and plane.Figure 32 table 32 reference 53...
