Study On The Characteristics Of Physical Activity In Community Parks And Its Correlation With Environmental Characteristics

With the improvement of the people's material and cultural life and the development of the "Healthy China" development strategy,people's health issues have been given more attention.Physical activity(PA)can prevent various physical and mental diseases and improve public health.Urban public space with good accessibility is the main carrier for outdoor physical activity.As an important public space for daily use by residents,community parks still follow the greening direction to meet the requirements of rest and aesthetics.How to meet the demands of physical activities has become an urgent problem for community parks.In order to promote the role of community parks in physical activities,it is necessary to conduct an in-depth study on the occurrence characteristics of physical activities in community parks and how the environmental characteristics in community parks affect the occurrence of physical activities,so as to improve the understanding of the function of green space and provide theoretical support for physical activity-supported parks.This article takes 4 community parks in Gusu District,Suzhou as examples,conducts investigations on physical activities through systematic observation,uses statistical analysis to describe the time and space characteristics in detail of physical activities in community parks.Then based on landscape elements and spatial feelings difference,the internal spaces of the community parks were classified.At last,the correlation between the regularities of physical activity and the internal environmental characteristics of the community park was analyzed,and the contribution of different types of spaces to physical activity was explored.Finally,the following three conclusions were drawn: 1)In terms of the use of subject characteristics,the senior are the most common in age,and they mainly engage in sedentary behavior;the number of men in gender is greater than that of women,and the number of men is the most at noon,mainly sedentary behavior;Women are more active in the morning and evening,mainly moderate-to-vigorous physical activities(MVPA);2)The use of different intensity of physical activities on the venue: sedentary behavior(SB)are more likely to appear around the facility, and appear more frequently at the edges;moderate-to-vigorous physical activities(MVPA)often occur in a large,spacious space with good accessibility,or a space with certain facilities to rely on;3)Intensity of physical activity and spatial correlation: The density of sedentary behavior is greatly affected by the adequacy of rest facilities,followed by accessibility.The site canopy coverage is high,generally an independent small-scale space(<144m~2),of which chess and card activities are biased towards spaces with strong privacy,and rest behavior tends to be a space with an open view.This kind of the space is mostly near the water;areas with a high density of light physical activity(LPA)are close to entrances or highly active sites,often appearing in waterfront areas,and the main activities are walking;Moderate-to-vigorous physical activity(MVPA)with high density have good accessibility,the physical activity of singing and dancing groups requires the largest space(> 576 m~2),the line of sight is high,and the space form is closest to the square;144 ~ 576 m~2),with medium sight opening and adequate rest facilities;yoga(stretching)venues have a small area(<144m~2),closed sight,and need facilities that can assist stretching.
