Evaluation And Optimization Of Thermal Comfort In Micro Green Space At High Temperature

In recent years,global warming has brought about changes in ecosystems,and the rapid expansion of cities has intensified this change,leading to frequent floods and droughts in some areas.In the city,the extremely high temperature that frequently erupts also causes harm to the human body,which has even become a worldwide public health problem.As the main ecological environment of the city,natural elements such as green space and water body can effectively regulate and improve the local microclimate and alleviate the urban heat island effect.However,in the high-density urban areas where land use is tight and the activity space is sparse,many micro-green spaces containing natural elements are not effectively utilized.Chongqing Yuzhong is a typical high-density urban area.The problem of thermal comfort in the use of micro-green spaces is high.Therefore,the author looks for the micro-green space in the high temperature and high-density blocks in the high temperature background,and studies its thermal comfort.Based on site investigation,actual measurement and software simulation to analyze the problems of thermal comfort of the site,the corresponding optimization measures are proposed for the improvement of thermal comfort in micro-green space,which provides reference for the construction of micro-green space under high temperature,and promotes urban space refinement and ecology.Development.Based on this concept,this paper mainly discusses the argument through four chapters.Firstly,the second chapter reviews the concept of micro-green space and the optimization of thermal comfort.The characteristics and definition of the micro-green space,the general research on the thermal comfort theory of the micro-green space,the thermal comfort evaluation method and the influencing factors and optimization ideas of the thermal comfort are sorted out to provide support for the latter.Then in the third chapter,the characteristics and location of the micro-green space in Chongqing’s high-temperature neighborhoods are studied.By analyzing the summer heat in Chongqing and the urban heat islands,the severity and cause of high temperature in Chongqing are clarified.The high temperature block was selected by surface temperature inversion,and the location of the micro green space in the middle three areas of Yuzhong District was determined.The position of the micro green space was measured,and the specific research position was clarified later.In the fourth and fifth chapters,the process of microclimate measurement,thermal comfort simulation evaluation and analysis,optimization measures and inspection optimization effects of micro-green space are elaborated.By comparing the measured data of the measured points,the differences between the micro-green space and the ordinary space and the traditional green space are improved.The thermal comfort simulation of the micro-green space is used to summarize the spatial and temporal distribution of the thermal comfort of the micro-green space.problem.Finally,combined with the problems existing in the use of micro-green space,an optimization scheme is proposed for the micro-green space,and the thermal comfort test is improved by comparing the simulation effects before and after the change.Through research,this paper obtains the variation law of the measured parameters of the micro-green space climate and the spatio-temporal distribution of thermal comfort,and provides suggestions for the thermal comfort optimization of the micro-green space according to the influencing factors of the thermal comfort of the micro-green space combined with the site use.It can provide scientific reference for the construction of micro-green space,and has practical significance for creating a comfortable and comfortable space environment in high temperature and high-density urban areas.
