| With the development of China’s economic and urbanization,the Residents’ living standards have been improved,the burden of city environmental has gradually increased.Residents have gradually imposed more extensive and detailed requirements on urban climate.The wind environment is used as wind comfort and pollutants to disperse.The main factors that solve the problem of discomfort caused by dry and hot climates are increasingly becoming an indispensable factor in urban planning.The main research object of this thesis is the Panzhihua South Station area with special climate environment.The data query and CFD software physical environment simulation method are used to obtain the wind environment characteristics that are more in line with the real situation.Based on this result,the results are proposed.Renovate the wind environment of the site to improve the quality of urban life,meet the needs of use,and create urban design with regional characteristics.The design stage begins with the macro level of urban design,that is,the urban form,geographic unit,and landscape pattern to discuss the correlation between urban wind environment and urban spatial form.Through the middle-level open space shape and distribution pattern,the coordination organization of the road grid bureau and the greening system forms an effective ventilation route plan,and combines the ventilation system with the functional group mode and the neighborhood space to complete the urban design plan.Through the simulation of the wind environment data of the new scheme,thedistribution of the comfort level of the pedestrian wind environment is evaluated at the macro level.The mesoscopic level is compared with the wind environment comfort of each functional group space and different layout forms,and its characteristics,problems and The solution is to evaluate and analyze the wind environment of the road grid and open space,and finally summarize the impact of various elements of urban design on the urban wind environment,and design the wind from urban aspects,functional groups and urban landscapes.The environmental optimization design method is summarized and summarized.Microclimate data simulation technology such as wind field is an auxiliary and inspection means for urban design.The goal of urban design is to create or improve environmental quality.The design starts with reasonable function and space quality.This study attempts to explore the rationality of urban design generation and verification methods based on the perspective of wind environment comfort. |
