Research On Healing Plant Landscape Design Of Urban Green Space From The Perspective Of Audiovisual Interaction

With the development of the times,more and more problems have threatened the psychological or physical health of contemporary people,according to statistics,the number of sub-healthy people in China has reached 70%,and health and other related issues have received more and more attention.The environment of individual life can greatly affect human health,environmental psychology and other related studies have proved that when the environment has the four characteristics of distance,attraction,degree and compatibility,it has a positive impact on individual recovery,and a number of studies have proved that urban green space has a positive effect on the healing of individuals,so it is crucial to give full play to the healing effect of green space plants and improve the overall health level of urban residents;In addition,vision and hearing,as the basic perception channels of individuals,are not only the main ways for individuals to receive information,but also important ways for individuals to perceive the environment.Almost 90% of the human body’s feelings are produced by audiovisual effects,so the study of the interaction between vision and hearing and its perceptual impact on individuals and groups is worth in-depth study.In this study,audiovisual interaction is taken as the starting point and the healing effect and influencing factors of green plant landscape are studied for the purpose of individual healing.Specifically,based on the three types of green space soundscapes: park soundscape,residential area soundscape and street soundscape,the healing effect of plant landscapes with different characteristics is explored,its laws are summarized,and the factors affecting the healing effect are clarified,so as to provide methods and reference for improving the overall quality of urban green space.The study adopts literature reading method,survey method,experimental method,statistical analysis method and other methods to conduct comprehensive analysis and investigation based on the main research scenarios of Nanjing park,residential area and street green space.Firstly,a total of 30 places in three types of urban green spaces in Nanjing were investigated to clarify the current status of soundscapes and plant landscapes in the three types of green spaces.At the same time,the experimental materials were collected,and the content of the materials were the sound scene audio and plant landscape photos of each site;Secondly,by analyzing the soundscape characteristics of each type of green space,the soundscape characteristics and plant landscape composition of the three types of green space were summarized,and then the soundscape with this feature was synthesized by computer technology as the auditory material corresponding to the experiment,and at the same time,six of the three groups of greenland photos were selected as visual materials,and the six visual materials were combined with the corresponding auditory materials,plus 3 audio-only control groups to obtain a total of 21 audiovisual evaluation materials,and each group of audiovisual evaluation materials included 1 audio control group and 6audiovisual combinations.Then,three groups of evaluations were carried out by the test subjects;Finally,the three groups of photos were quantified for landscape features,and the mean,reliability and validity,correlation,linear regression and other analyses were carried out using R language and SPSS26 to explore the relationship between plant landscape features and healing effects.Through analysis,it is found that when the soundscape is an individual’s preferred situation,the degree of increasing visual elements affecting the healing effect of the environment is relatively low,and when the soundscape is an individual resistant sound,the healing effect is greatly affected by vision.In other words,the soundscape experience lays the foundation value of the healing effect,but in a noisy sound environment,the visual landscape can more obviously affect the healing effect of the environment.Under the sound landscape conditions of the park,there was a positive correlation between the area of the lawn and the healing effect,and the larger the proportion of lawn,the better the healing effect.Under the sound scape conditions of residential areas,the healing property seems to be related to the presence of water features and the color temperature of the landscape,and the environment with water features and cold color temperature has obvious healing effects on individuals.In the street soundscape environment,the degree of individual healing is greatly affected by vision,among which the healing effect is related to the proportion of sky,the proportion of plants,the degree of pruning,the planting method,the scale of the landscape,the distance of the landscape,the degree of spatial openness and the presence or absence of visual focus,among which the larger the proportion of sky,the more obvious the degree of pruning,the neat the planting,the larger the scale of the landscape,the farther the distance of the landscape,the more open the space,and the stronger the healing effect of the spatial environment with visual focus on the individual.The proportion of plants and the healing effect of the environment showed a significant negative correlation,that is,the greater the proportion of messy plants in the line of sight,the worse the healing effect of the individual.This study focuses on the healing effect of plant landscape from the perspective of audiovisual interaction,uses quantitative research techniques to explore the relationship between plant landscape characteristics and environmental healing effect under the existing three types of soundscape,analyzes the factors affecting the environmental healing effect,provides a design reference for improving the healing effect of plant landscape in different sound environments,and also provides a theoretical basis for the design and transformation of urban green space plant landscape.
