Research On The Influence Of Spatial Form Commercial Complex On Microclimatic Environment In Severe Cold Regions

The urban commercial complex is the inexorable trend of the development of urban form,the transformation of urban commercial and the upgrading of people's consumption.The crowd activities are more intensive,and its external space is the continuation of urban space,which is in urgent need of further attention.At present,the construction of most urban commercial complexes does not fully take into account the climate characteristics of the severe cold regions,resulting in the poor microclimate environment of its external space.Therefore,this paper takes the urban commercial complex in severe cold regions as the research object,to study the influence of spatial form on microclimate environment,in order to enhance the comfort of people's activities.Through the classification and investigation of the spatial forms of the urban commercial complex in the severe cold regions,the Harbin Qunli Broad Center is selected as the field investigation object.In order to summarize the change rules of microclimate environment in each season and the basic condition of each measuring point,the investigation plan was made to measure the microclimate environment on the spot.On the basis of field investigation data,this paper comprehensively discusses the four seasons of spring,summer,antumn and winter,the two types of outdoor and semi-outdoor,the four microclimatic environmental factors of solar radiation,temperature,wind speed and humidity to clarify the quantitative relationship between microclimatic elements in different spatial patterns,and the effects of spatial patterns on microclimatic environment are analyzed.At the same time,combined with the way of subjective questionnaire investigation,the thermal comfort of human beings was studied based on their actual feelings,and the influencing factors of microclimatic environment in different seasons were determined,the statistical perception intervals were calculated,and the regression equation was predicted.On this basis,the spatial form of the commercial complex is divided into positive space,general space and negative space,and put forward the spatial utilization strategies for the positive space and negative space.The purpose of this paper is to study the effects of different spatial forms of urban commercial complex on microclimate environment,and to classify the space of Harbin Qunli Broad Center with the study of thermal comfort,and put forward the optimization strategy based on the status quo to enhance the regional vitality.At the same time,it provides the basic research of mocroclimate environment for the urban commercial complex in the severe cold region,and also provides an effective reference for the evaluation of thermal comfort.
