The Wind Environment Under The Influence Of Urban Commercial Space Form Optimization Strategy Research

With the continuous improvement of China’s economic level and the acceleration of urbanization process,the scale of urbanization is also expanding.Is constantly enhance its capability of our country is in the construction period,our country’s urban spatial morphology is changing so much.This rapid urbanization improves people’s quality of life,but at the same time,rapid urbanization has become a burden on the environment.Urban wind environment is an important part of urban microclimate,which is conducive to eliminating air pollution and dissipating heat flow.In addition,in the cold north,the wind environment brings people discomfort to some extent and affects people’s outdoor travel frequency.Urban business district is the core area of a city.It is an important place for people’s entertainment and activities.The urban wind environment problem is prominent.In order to create a good outdoor environment,it is very important for the reasonable ventilation and wind proof of the urban commercial area.From the perspective of planning,this paper conducts numerical simulation analysis of Shenyang Commercial District,finds out the current influencing factors of the spatial form of the commercial district,discusses the correlation between the influencing factors and the spatial form of the commercial district,and looks for the optimization factors of the spatial form of the urban commercial district,so as to provide reference strategies for building a good wind environment of the commercial district.Search and sort out the relevant data of outdoor wind environment evaluation standard,conduct basic field investigation on the building height,building density,building volume,greening rate and other factors of the urban business district,and provide basic design data for the simulation model of the proposed urban business district.Taking Taiyuan Street and Zhongjie Street in Shenyang as examples,this paper analyzes the wind environment at pedestrian height in summer and winter,and analyzes and evaluates the basic distribution characteristics of spatial wind environment in Shenyang commercial district.From a single building,construction group,street space,the square space,these four space form factors to explore the influence of urban business district wind environment and the space form.Through numerical simulation,the distribution characteristics of commercial wind environment and the reasons for the existence of low wind area and high wind area are analyzed qualitatively and quantitatively.Finally from individual buildings,building groups,the street space and square space four aspects put forward urban business district space form the wind environment optimization strategy.
