Study On Microclimate Design Strategy Of Landscaping Buildings In Urban Parks In Hot And Humid Areas

With the development of the socialist market economy,the living standards of the Chinese people have been greatly improved,but many environmental problems have followed.The problem of global warming and human living environment pollution is imminent.The high-quality living standard makes people have higher requiremen ts for urban parks.Urban parks are not limited to providing a place to rest.More and more people begin to pay attention to the comfort of urban parks.Most of the existing studies are about the microclimate of green space and water system in urban parks,and most of the landscape buildings in urban parks are about the overall planning,building materials and building form.Most of the landscape buildings in parks have ancient form,poor shading and cooling effect and low utilization rate,which provides an opportunity for this paper to study the microclimate design strategy of landscaping buildings.Firstly,it expounds the necessity and urgency of studying the microclimate of urban park landscaping buildings under the background of climate problems brought by urbanization,the call of park city policy and the normalization of epidemic situation.By combing the previous research on landscaping buildings and microclimate,we find the key points that have not been paid attention to in the research,and then p ut forward the research direction and content of this paper.Secondly,taking Xiamen as the representative of hot and humid areas,this paper summarizes the climatic characteristics of Xiamen in four aspects:temperature,solar radiation,relative humidity and wind speed.This paper investigates and analyzes the landscaping buildings of Xiamen City Park,including the classification function,constituent elements,storey height,architectural form,building materials and building underlying surface.The factors affecting the microclimate of landscaping buildings are analyzed to provide basis for the actual measurement.Investigate and summarize the existing microclimate design of landscaping buildings in Xiamen urban park,and analyze the shortcomings of exi sting shading,cooling and ventilation,so as to lay a foundation for further research.Thirdly,through field measurement and laboratory measurement,three groups of measuring points in Xiamen Zhongshan Park are measured to study the relationship between building orientation,building roof,surrounding plants,surrounding water elements and landscaping buildings microclimate;Replace the shading materials and cooling facilities for the landscape buildings in the laboratory,compare the shading and cooling effect,and provide technical support for the next strategy.Then,the subjective comfort of landscaping buildings is studied through questionnaire survey.Through the observation and tracking of crowd activities in landscaping buildings,the activity pref erence,thermal feeling preference,the correlation between different activities and landscaping buildings,the correlation between different activities and comfort,the correlation between activity duration and microclimate of landscaping buildings,and t he adaptability of activity theme to landscaping buildings are explored,Finally,through the opinions collected and the results of questionnaire survey,the optimization direction of landscaping buildings design based on microclimate comfort is obtained.Finally,combined with the results of experiment and questionnaire survey,the microclimate design strategy of landscaping buildings is obtained from five aspects: building orientation,building roof,active cooling facilities,surrounding plants and surrounding water bodies.
