The Study On The Landscape Visual Comfort Factor Of Yinhe Park In Hefei City

In recent years,with the continuous improvement of the urban residents' requirements for high-quality and comfortable landscape environment,the existence of some parks that are older can no longer meet the comfort needs of tourists.Although the basic visual evaluation theory method can evaluate the landscape quality of urban parks,the visual comfort experience of tourists themselves is ignored in the evaluation process.The evaluation of the landscape quality of urban parks lacks the evaluation of tourists' subjective visual comfort and is limited to Analyze and evaluate the existence of objective factors in the park,lack of comprehensive considerations on the subjective level of people,and fail to summarize the relevant factors that have a major impact on the visual comfort of tourists in the design.In this paper,Yinhe Park in Hefei is taken as the research object.To summarize the relevant elements of visual attraction in visual evaluation theory,combined with the visual comfort evaluation theory at home and abroad,the visual comfort evaluation factors of comfort landscape are determined: the size of the space,the frequency of space transformation,and the transparency of the sight of the landscape Sex,the richness of colors,the saturation of colors,the basic form of planting arrangements,the beauty of plants,the regional characteristics of the site,the design style,etc.Based on this,an evaluation index system is established.Based on the subjective semantic questionnaire survey,the data obtained after the summary is used as a reference to determine the mathematical relevance of each evaluation index factor to comfort.The correlation between the factors,the comprehensive factors that have an impact on visual quality are analyzed in turn,and the regression mathematical model between the factors is established.Summarize various objective index elements in the Galaxy Park through map data software and photos taken on the plot: spatial scale,node distribution,plant level richness,etc.,combined with mathematical models for analysis,evaluation and summary,and obtained relevant conclusions:(1)The overall visual quality of the park is generally evaluated,and the overall score is in the range of 0.00 to 1.10.The positioning of the park lies in the community service parks under the ring city park system,which can only be satisfied with the daily production and entertainment activities of the residents in the neighborhood,lacking distinctive themes and strong regional characteristics.(2)After analysis and processing of the questionnaire data obtained,comprehensive factors that have a major impact on the visual quality of the park are obtained.Factor?(environmental factor)and factor ?(atmospheric factor)affect the visual landscape environment of the crowd.For quality evaluation,in the visual landscape environmental quality rating of the park,the evaluation factor I occupies 62.80%;the factor II is 28.74%.(3)For comfort evaluation,a multiple linear regression equation is to be established to further clarify the mathematical model between each factor and comfort evaluation,and the following conclusions are obtained:F=0.319+0.152V2+0.107V3+0.222V4+0.101V6-0.262V7+0.356V8+0.214V9(V9 landscape sight,V7 plant configuration,V2 space arrangement,V6 color richness,V3 space change,V8 plant beauty,V4 space size)R2=0.949The factors that have a greater influence on the degree of comfort are(judgment based on the absolute value of the value),the aesthetic degree of plant landscaping(0.356),the arrangement of plants(|-0.262|),the size of the spatial scale(0.222),the sight of the landscape Permeability(0.214),hierarchical arrangement of space(0.152),frequency of space change(0.107),richness of color(0.101)In the landscape visual comfort evaluation of Yinhe Park,the influencing factors of plants dominate.The aesthetics of plants and the specific methods of landscape configuration greatly affect the subjective evaluation of tourists;the second is the people who are affected by the specific size of the space.The range of sight and social distance in turn affect comfort;whether the sight of people is restricted,the primary and secondary relationship of the space and the frequency of conversion affect the psychological and physiological stimulation of people,which affects the assessment of visual comfort to a certain extent;Finally,color has a correlation with comfort under the stimulation of human eyes.
