Study On Characteristics And Environmental Support System Of Children's Independent Mobility In Hong Li Community Of Shenzhen

Children's independent mobility is an important source of children's daily physical activity,which is of great significance to ensure the healthy development of children's physical and mental health.The increasingly complex city community built environment has led to a decline in children's independent activiti es in a certain extent,to promote the independence of children has become an important task to ensure the healthy development of children,and the city community as the main place for children's daily activities,has become the main research field of spat ial independence activities for children.But the children's independence activities occur not only on the public space of the community's own characteristics,but also by the children's travel habits,basic characteristics and community understanding of t he system only children's travel activities of the built environment influence factors,can effectively explore the child friendly community to promote children's independence activities construction strategy.Therefore,this study selected Shenzhen City H ongli community as the research object,research and analysis of spatial behavior characteristics of community public space within the children's independence activities,combined with the community public space and the surrounding built environment features built to explore the environmental impact of children's independent activities of the temporal and spatial distribution of factors.This paper is based on the geographic information system,the use of field research,behavior research,geographic map encoding and spatial analysis technology,the distribution of the collection,statistics and presentation of Hongli community children's independent activities in the community,every road in the public space and its change characteristics in the time dimension.At the same time,combined with the existing research results,the built environmental impact factor database was built,and the theoretical model was constructed.The environmental factors affecting the spatial behavior characteristics of children's independent activity were discussed through statistical analysis.The study found that the spatial accessibility,Education ancillary facilities accessibility,school accessibility,stores,retail stores,the number of other activities,the crowd shade effects independent activities and children health environment has positive correlation.There are recreational facilities,rest facilities,motor vehicles,lighting facilities,space organizations for parks,children's play facilities,and there is no significant correlation between children's independent activities.There was a negative correlation between site size and children's independent activities.There are recreational facilities,rest facilities,motor vehicles,lighting facilities,children's playground facilities,there is no significant correlation between the scale of the site and the independence of children.Therefore,the community built environment must provide the support of children's independence activities through space security and accessibility,stimulate the independence activities of children through the configuration of commercial facilities and activities of children,and enhance the psychological.
