Research On The Environmental Characteristics Of Children’s Natural Playground From The Perspective Of Mental Health

The health performance of urban blue-green spaces has been confirmed by a large number of empirical studies.However,the influence of urban blue-green spaces on children’s mental health still has many controversies,especially the influence of blue-green spaces on children’s instantaneous emotions.This article combs the impact mechanism of urban blue-green space on children’s mental health,and proposes that urban blue-green space promotes children’s different activities through the construction of a diverse and heterogeneous game environment,thereby affecting children’s mental health conjecture,and explores natural games The impact of the field on children‘s emotional perception.The structure of the full text is as follows:The first chapter is the introduction,which mainly elaborates the background,purpose and significance of this research.It summarizes the related researches on the impact of urban blue-green space exposure on children’s mental health in 2010 at home and abroad,and finds that children play in the blue-green space Experience may explain the difference between children‘s emotions and restorative perception better than the environmental characteristics itself;the concepts of children,natural playgrounds,and children‘s mental health have been defined,research methods have been clarified,and technical routes have been sorted out.The second chapter combs the relevant research of child-friendly open space under the theory of availability,and combs the technical means of availability evaluation and quantitative analysis methods of availability for the evaluation of children’s activities in blue-green space;based on the theory of availability The classification method of environmental characteristics from children’s perspective has determined 7 categories and 26 environmental characteristics indicators,and constructed a natural play field environmental evaluation index system based on availability theory;summarized and compared measures of restorative perception and emotional perception for children Methods to establish a framework for the development of experiments.The third chapter combines the drone technology to complete the assessment of the environmental characteristics of the natural playground,and prepares for the analysis of the space use of children’s activities;the use of drone observation methods,and the availability-based observation program for children’s activities as the children of the natural playground The activity observation framework observes children’s activities in natural playgrounds;with the help of behavioral annotation method,in Arc GIS,different demographic characteristics,activity types,physical activity levels,social activity levels,and activity time of children active in the playground are analyzed Segment and other information are marked and sorted;the PAD three-dimensional emotional model is used to evaluate children’s emotional perception in the natural play field.The fourth chapter describes and statistically analyzes the characteristics of children‘s activities,compares and summarizes the differences in the total samples,the differences in time and space,and the differences in the demographic characteristics of children‘s activities and their inherent laws;using nuclear density analysis and correlation analysis,it is found that children‘s activities are related to The seven environmental categories of the affordability theory have typical correlations;the paving area,the types of fixed game devices,and the types and numbers of mobile game devices support children’s walking,running,rotating and other activities as well as middle and high-level physical activities,thereby promoting Children‘s perception of pleasure,arousal,and available seasonal flower/fruit plant species are significantly related to higher levels of social activities,and at the same time promote children‘s three-dimensional emotional perception.Finally,combined with the experimental results,at the planning level,three aspects are proposed to improve children‘s exposure to urban blue-green spaces,develop urban blue-green space virtual reality environments and children‘s participatory design,and improve the research on urban blue-green spaces that promote children‘s health—practical frameworks.Strategy: At the design level,it is pointed out that in the design of natural playgrounds and other urban blue-green spaces,the design schemes should be evaluated and weighed in three aspects: nature and man-made,safety and adventure,filling and blank.The fifth chapter summarizes the full text,discusses research deficiencies and improvement methods,and looks forward to the possibility of future research.
