Investigation On Microclimate And Comfort Level Of Tourists In Urban Public Space

With the continuous and rapid progress of urbanization in China,a large number of people are pouring into urban areas to seek survival.In 2019,China’s urbanization rate has exceeded 60%,and it is expected that,China’s urbanization rate will exceed70% by 2030,close to the level of developed countries.The rapid promotion of urbanization will inevitably lead to changes in urban form and a series of "urban diseases".Among them,The deterioration of the urban ecological environment has the most serious impact on the daily production and life of urban residents.Since the last century,more and more scholars have noticed the influence of urban climate on the life of urban residents,and the quality of local microclimate in cities largely affects the quality of people’s lives.Therefore,the study of urban microclimate environment is very important for the improvement of human living environment and urban microclimate.In this study,Zhang jia kou Sheng Li Park was selected as the research object,through measuring the main microclimate elements in the park in one year.The microclimate elements and the changes of microclimate comfort were analyzed from the perspective of time and space;collect tourists’ comfort by issuing questionnaires,SPSS software was used to analyze the correlation between comfort.The effects of different landscape elements on microclimate elements and comfort in winter and summer were studied.The following conclusions are drawn.The microclimate comfort perception of the park in all seasons is as follows,spring: "comfortable,feel comfortable";summer: "hot,uncomfortable";autumn: "very cool,most people feel uncomfortable ";and winter: "very cold,extremely uncomfortable".The four seasons are ranked in order of comfort: summer,spring,autumn and winter.Relative humidty had the greatest impact on comfort in spring and summer,air temperature has the greatest impact comfort in Autumn,air temperature has the greatest impact comfort in autumn,wind speed has the geatest impact on comfort in winter.In summer time,different forms of substrates influence microclimate comfort in the order of degree: hardened road,masonry pavement,grass;different types of plants influence microclimate comfort in the order of degree: grass,trees,mixed trees and shrubs.In winter time,the degree of influence of different underlayment forms on microclimate comfort is ranked: grass,masonry paving,hardened roads;the degree of influence of different plant types on microclimate comfort is ranked: grass,trees,mixed trees and shrubs.Finally,this study adjusts the microclimate comfort of the park from the through shading and ventilation,specifically increasing facilities reasonably,adding water bodies,ventilation and cooling in summer,and wind protection and heat preservation in winter,so as to improve the overall use of the park.
