Evaluation And Application Research Of Garden Light And Shadow Space Visual Perception

"The ear is the sound,the eye is the color",the body is in nature,the vision and the sense are inseparable from the existence of light,and the light and shadow are like two poles,complement each other,the two can be the space image.The carrier can also be the main body for creating a space atmosphere.Sunrise and sunset,the change of seasons,the existence of light and shadow in the garden space between the changes of the day and night will affect people’s emotional ideology and then produce different visual feelings,and find the unchanging essence in various different real feelings and uncertain image feelings.It is the significance of the visual perception of garden light and shadow space.The article through the domestic and international light and shadow art and landscape visual perception evaluation and other related areas of research and summary of the study,as well as light and shadow,garden space and visual experience and other related concepts and relationships.From March 2017 to October 2018,the author selected Suzhou Liuyuan and Humble Administrator’s Garden;Shanghai Fangtayuan and Chenshan Botanical Garden;Beijing Xiangshan Hotel,Xiangshan Park;Xi’an Banpo International Art Park,Expo Park and Jinan Daming Lake In the gardens and green spaces of different regions and different natures in the north and south,the field investigation and research on the application of light and shadow in the landscape space is carried out.Through the methods of garden light and shadow space observation and recording,plane mapping and framing shooting,the application status and design performance of light and shadow in garden space were investigated.Analyze the role of light and shadow in the landscape space and design techniques.At the same time,through the personal interviews of tourists,the degree of attention and satisfaction of different light and shadow spaces were investigated and analyzed,which provided the basis for the evaluation of light and shadow in the visual perception of garden space.Based on the investigation on the field,13 types of plotting space in the Daming Lake Scenic Area of Jinan were selected as the research object.Among them,4 open(KC)spaces,6 semiclosed spaces(BFB)and 3 closed(FB)spaces,using the SD method,select 24 evaluation factors,and extract 5 by questionnaire and data analysis.The common factors affecting the visual perception of garden light and shadow space(ambient factor,environmental factor,visual factor,perception factor,place factor),construct a visual perception evaluation system of garden light and shadow space,combined with the weighted weights of various common factors to obtain 13 The results of the visual perception evaluation of the sample site are: BFB-6>KC-4>FB-1>FB-3>BFB-4>BFB-3>BFB-5>BFB-1>KC-3>FB-2>KC-2>KC-1>BFB-2,finally concludes by summarizing the investigation and analysis of the application of light and shadow in landscape space and the evaluation results of the plot of DaMing Lake:(1)Light and shadow is the most basic of human visual perception The elements,natural light and shadow,through the action of human vision,render the physical elements of the garden space and create the artistic conception to give people a sense of spatial experience;(2)Different spatial types have different light and shadow form beauty,and reasonable adjustment of various elements in space Material form The mass scale and the structure level collide with the light and shadow to produce rich visual changes and spatial feelings.(3)The light and the shadow are two poles,the light changes in real time and the shadow moves with the light.The creation of light and shadow space is a kind of full design of art.The correct positioning space function and the space atmosphere that needs to be created,and the spatial scale of light and shadow can be controlled to create a sustainable landscape space with light and shadow as the starting point.
