Study On The Correlation Between Thermal Comfort And Activity Behavior Of Community Parks In Beijing Central District

With the rapid development of urbanization,people's demand for comfortable living environment is also increasing.Community park green space is an important part of the landscape that serves residents' lives.It also plays a key role in regulating the microclimate of landscape gardens.A good community park environment can attract residents to get close to nature.As a megacity,Beijing's increasing ecological environment and insufficient space for activities need to be resolved.The Beijing Urban Master Plan(2016-2035)proposes to improve the city's green space system,to significantly expand the size of green space,and to improve the quality of ecological services.For urban park rings,it is required to increase the proportion of green open space.It is of great significance to further study and optimize the structure of community parks and improve the quality of green space.It is well known that strengthening outdoor activities is beneficial to physical and mental health,optimizing urban public space is conducive to promoting the development of people's outdoor activities,to enhance national physique.This article mainly discusses the tendency of people's activity preferences and behavior changes under the influence of changes in thermal comfort in the community park environment.Firstly,the concepts related to the current research on thermal comfort and behavioral activities and the research progress at home and abroad were sorted out,and the background and current situation of community parks in the central urban area of Beijing were briefly explained.Then,a total of six community parks were selected as representative representatives in each central urban area,and the correlation between the environment and human activities was studied in depth.Climate data were obtained through field monitoring,behavior observations,questionnaire surveys,and visitor interviews were used to obtain visitor activity time,Space and purpose of the event.Based on the measured data,an effective community park environment model is established and verified by climate software.Regression analysis was modified to obtain the PET thermal neutral value of each typical park at 20.85 ° C,and the comfort evaluation level was divided according to the obtained regression equation.Using the revised PET index to draw the thermal comfort distribution map of community parks.Combining space and activity content,we analyzed the difference in comfort levels between different winter and summer seasons at 10 am and 16 pm.Then,statistical software calculates and compares the climatic and environmental factors,the laws of thermal comfort changes,and the laws of human behavior changes,and derives their relationship in time and space.Finally,the landscape design method was used to optimize the reconstruction of Huangqu Park in Chaoyang District to enhance the comfortable environment and attract tourists.Based on the above research,the paper puts forward some suggestions on the optimization of community park environment,which can provide more effective basis for residents' activity space in the future planning and construction.
