Research On Birdsong Soundscape Of Urban Parks Based On Perceived Restoration

Rapid and high-pressured rhythm of life will aggravate the mental burden of urban residents,which will endanger people's physical and mental health in the long run.According to Kaplan's attention-recovery theory,an enchanting,fugitive,compatible and malleable environment can provide a comfortable resting space.As a green space in the city,the city park is the main place to relieve stress and restore attention.It can bring a healthy and relaxed outdoor environment for the physically and mentally handicapped urban population.At the same time,sound,as one of the indispensable elements of the environment,has also had a positive impact on perception recovery.Taking Harbin Sun Island Park as an example,this study selects bird sound as the most restorable sound source,uses the soundscape perception recovery scale as an evaluation tool,selects the path profile by space syntax and grid pixel method,Morphological characteristics and the characteristics of the samples were summarized and summarized,and statistical analysis software SPSS was used to expand the data analysis to obtain the comparison results of perceived recovery benefits of visual and audiovisual interaction,as well as the correlation between the features of green land,relationship.First of all,the paper studies on the natural soundscape of the domestic and foreign literature through the literature review to determine the sound source for the study of birds,combined with the main body of the study and quantitative evaluation of green space features literature review selected the sky index,soft and hard ratio and vertical cover as the study of green space characteristics,And in the experimental process design to the soundscape recovery scale as the main evaluation questionnaire.Secondly,summarizes the basic situation of Harbin Sun Island Park,selects the path space with high concatenation,high integration and low depth by space syntax,selects the appropriate eight sections from them,takes the visual image of the path section as the research object,The morphological characteristics of the path space are concluded.The proportions of the landscape elements and green space features of the path profile are calculated by the grid pixel method,and the sound environment decibel values of each sample site and section are compared to analyze the space types of the site and the section,Features and other elements.Thirdly,from the point of view of the attributes of the birds,the effects of the height of the birds,the size of the birds and the types of the birds on the recovery of the perception are discussed.The benefit of therecovery of the perception under the interaction between the visual and the audiovisual is analyzed comparatively.Based on the analysis results,Ming environmental mode.Finally,using Spearman and stepwise regression analysis to analyze the correlation between sky index,soft and hard ratio,vertical cover and perceived benefit of recovery,we propose some more meaningful suggestions on the planning and design of the bird's eye view in urban parks.In this paper,through discussing the benefit of bird-perception recovery in the typical path of urban park,the paper analyzes the correlation between the characteristics of bird-song and the characteristics of green land and the recovery of perceptual value.It is of great significance for the future planning and design of urban park and its path space and bird habitat Path optimization in the ground to provide guidance,and strive to maximize the recovery of the soundscape environment.
