Research On The Characteristics Of Audiovisual Elements In The Restorative Environment Of Community Parks Under Different Behavior Types

The development of urbanization continues to squeeze the living space of urban residents,and parks have received widespread attention as a way to solve residents’ health problems.A large number of studies based on indoor experiments have shown that the community park environment can promote the health of people from the perspective of visual experience.However,there is a lack of restorative research on the outdoor environment’s audio-visual experience of users under different behavior types.Therefore,this study takes Huangzhong Park,Tea Culture Park and Jiulidi Park in Jinniu District of Chengdu as the research objects,records the behavior and demographic characteristics of park users through behavioral observation,and uses kernel density analysis method Explore the spatio-temporal relationship between user behavior and community parks,extract and analyze the typical spaces of different behaviors in community parks;secondly,collect the psychological recovery and characteristics of community park users in different behavioral typical spaces through questionnaire survey and statistical analysis Perceptual evaluation,to determine the key features of vision and hearing that have the most restoration potential in typical spaces of different behaviors,in order to propose targeted design strategies for the restorative environment of community parks,and provide new ideas for the study of healthy human settlements.The research results of this paper mainly include the following 4 points:(1)Demographic characteristics and distribution of community park users based on different behavior types:According to field research,users have 15 behaviors in community parks,among which sitting,chatting and walking are the most frequent.From the perspective of the age of users,community parks are dominated by middle-aged people(34.9%)and elderly people(43.3%),both of whom tend to sit quietly and chat among static behaviors.Children’s behavior is mainly playful,while young people are more chatting and walking.From the perspective of gender,males are mainly static behaviors,accounting for 46.7%.Women are more passthrough behaviors,accounting for 44.8%.Static behaviors are mainly in spaces with concentrated recreational functions,dynamic behaviors are concentrated in open square nodes,and passing behaviors are concentrated in park trails(2)Typical space extraction and analysis of different behavior types of community park users:Finally,7 typical spaces for static behaviors were extracted,mainly chatting behaviors(45.8%),and a large number of recreational facilities were built in the spaces.There are 6typical spaces for dynamic behaviors,mainly dance and martial arts(28.2%),and there are often large open spaces or facilities for various purposes in the spaces.There are 7 typical spaces for passing behaviors,mainly walking behaviors(92.8%),which are usually the wide main roads in the park.(3)Characterization of key audiovisual elements influencing typical spatial restorative effects of different behavior types:Through the data analysis of the field subjective evaluation scores,the key audio-visual element characteristics that affect the restorative effect of the typical spaces of different behavior types are obtained,among which 8 are the typical spaces of static behavior(features of visual elements: plant color,number of recreational facilities,road comfort,road width,types of landscape sketches;features of auditory elements: traffic sounds,birdsong,singing),10 typical spaces for dynamic behavior(visual elements Features: road width,road surface comfort,number of rest facilities,rest facility comfort,fitness facility types,plant types;features of auditory elements: conversation,singing,running water,radio music),4 typical spaces for passing behaviors(visual elements: pavement comfort,road twists and turns;features of auditory elements: conversations,birdsong).(4)Restorative landscape construction strategies and models of community parks under different behavior types:According to the above conclusions,in the static behavioral space,a construction strategy with rich plant quantity and color,bird-friendly plant community,sufficient recreational facilities,comfortable road pavement,appropriate road width and rich landscape sketches is proposed.In the dynamic behavioral space,the construction strategy is rich in plant species,constructing a space that encourages social interaction,low hydrophilicity of the waterscape,comfortable road paving,appropriate road width,comfortable and sufficient recreational facilities,and rich fitness facilities.In the pass-through behavior space,the number of plants is abundant,the plant community is bird-friendly,the road pavement is comfortable,and the road is winding and winding.
