Research On Spatial Pattern Language Of Climate Adaptation In Xi’an City Park Based On Behavior Choice

Urban parks are places for residents to enjoy leisure and entertainment,keep fit,visit,communicate,avoid disasters and hold various large-scale cultural and artistic activities.The microclimate environment of urban parks directly affects the quality of urban residents.In recent years,the practice of urban park design dominated by function and aesthetics lacks consideration of climate.Many parks fail to make full use of the sites with better microclimate environment in their design.Some Spaces also lack microclimate regulation measures,leading to low space utilization rate and short space utilization time.In theoretical research,there is also a lack of research on the thermal environment and thermal comfort of spatial patterns suitable for different types of behaviors in different seasons.To solve the above problems,this article is based on behavior observation and microclimate,measured from the people in different seasons of the laws of time and space of behavior choice,in the research of xi ’an city parks during summer and winter seasons people choose all kinds of typical spatial patterns in each period in the thermal environment and thermal comfort,can adapt to corresponding season,meet the demand of the thermal comfort of corresponding period and behavior of climate adaptation space pattern,and finally summary for climate adaptation space pattern language.This study mainly includes the following parts:(1)Basic theory combing: By combing the evaluation theory of thermal balance and thermal comfort of outdoor public space and the influence theory of spatial form and spatial elements on the microclimate environment of urban parks,the theoretical basis of thermal comfort evaluation and spatial model extraction in this study was established.(2)Typical spatial model: Based on the field research,the urban parks within the third Ring Road of Xi ’an were classified based on the spatial morphological factors affecting thermal environment and behavioral activities,and a set of classification standards were established.According to the behavior observation of the selected park,the behavior types are divided into sports and fitness,daily exercise,leisure and entertainment,rest and other types,and the space types are divided into architectural space,square space,woodland space,water space,terrain space,grassland space and other types.Summarize the combination of various Spaces and surrounding Spaces to understand the scale characteristics of each type of space;The spatial and temporal distribution characteristics of winter and summer were summarized.On this basis,eight typical spatial patterns suitable for corresponding behaviors and time periods are proposed.(3)Typical space model microclimate measured and climate adaptation space language construction: to contain all the typical spatial patterns of city parks in microclimate measured,it is concluded that the influence of the space form features of space thermal environment principle,the measured thermal comfort evaluation of a comprehensive analysis of space comfortable in winter and summer time,to explore the climate of various types of behavior demand conditions;The microclimate environment improvement methods of various spatial models were analyzed,and the ideal models were established for software simulation to enrich the research results by changing some relevant variables in the models.Finally,various types of climate adaptation spatial models are proposed and climate adaptation spatial model languages are constructed.Based on the behavior choice of people in xi ’an city park in winter and summer,this paper studies the interaction between space model and thermal environment and thermal comfort,and proposes a variety of climate adaptation space models to meet people’s thermal comfort needs,providing a new perspective for the climate adaptation design of urban parks.
