Research On The Influence Of Urban Parks On Residents’ Physical Activity

In 2016,the world health organization released a new "epidemic situation" in cities: chronic diseases have become the most important cause of threat to the public health of the world,accounting for more than 60 per cent of all deaths.And research shows that physical activity plays an important role in reducing the incidence and mortality of chronic diseases.As a space carrier of physical activity,urban parks become an important entry point for improving public health.Therefore,further understanding the relationship between the characteristics of urban parks and physical activity is of great significance for improving the physical activity level of urban residents.On this basis,this thesis takes the parks in the urban center of Tianjin as an example,drawing out 6 parks from all the parks in downton Tianjin with the method of stratified sampling.Based on 529 valid questionnaires,and combined with field investigation and GIS spatial analysis,this thesis gets such characteristic subjective and objective data of the parks as the park area,proximity,facilities,and landscape.And on the premise of controlling individual socio-economic attribute variables,it explores the effects of the above characteristics on the frequency and duration of residents’ physical activities and duration of physical activity of residents and the difference between the subjective and objective indicators of park characteristics on physical activity.The core contents of this thesis consist of four chapters.In chapter two,it first defines the concept and connotation of physical activity and city park,reviews the relevant research process at home and abroad,and summarizes the research status and trend at home and abroad from two perspectives of the influence factors of city parks on physical activities and differences in the influence of subjective perception indicators and objective measurement indicators,providing a theoretical basis for the following research.It turns out that the existing domestic research mainly focuses on physical activity intensity,rather than the frequency and duration of physical activity;and for the research of influencing factors of urban parks,the main focus is on the internal characteristics rather than proximity of urban parks,and the focus less difference between subjective and objective indicators.In chapter three,it sorts out and screens the sample data with the help of SPSS statistical software and summarizes the characteristics of sample data,including attributes,physical activity and park characteristics;sifts the dependent variables,independent variables and control variables to construct the model through the analysis of the data,providing a data basis for the following research.In chapter four,by using multiple linear regression analysis,it constructs a multiple linear regression model based on individual socioeconomic attributes,characteristics of urban parks and physical activity from two perspectives of the frequency and duration of physical activity,analyzes the relationship between urban parks and residents’ physical activities,and summarizes the influencing factors and relations of urban parks on physical activities.In chapter five,according to the results of regression analysis,and combined with the actual research situation,it provides suggestions for the following urban park planning and design.Based on the above research,residents’ physical activity is mainly affected by objective indicators of park proximity(distance from residence to park),park facilities(number of rest/fitness facilities per unit area),park landscape(vegetation coverage),and subjective indicators of park proximity(Whether it is close to the place of residence),park facilities(satisfaction with facilities).Based on the above conclusions,it proposes optimization strategies such as improving the proximity of the park and building a "15-minute fitness circle";increasing the number of facilities and improving their comfort;and improving the green space compatibility and increasing the activity space.
