Research On Urban Vertical Control From Microclimate Perspective

In the four decades rapid urbanization process,with city space increasingly expanding,it also brought about large numbers of indispensable environment issues.Microclimate topics is tight relevant to people's life and directly influence their comfort sense and the quality of life.The wind environment topics is the fundamental part of the microclimate and have an impact on the atmospheric pollution,tropical island effect etc.as an important index for three-dimensional space of the urban area,city height formed diverse of artificial ground surface shapes based on cities' different values purpose and became the main factor which influence the near ground wind environment.This paper researches the city height controlling methods and tactics in urban planning design with the background of sustainable development.Choosing the view of the city wind environment,this research mainly focuses on the relationship between the city height and the wind environment to build the height controlling tactic to improve the city wind environment.This research simulates the city wind environment based on the computer simulation and it also connects the common index in the wind environment investigation with the index system in practical urban planning,Sketches center line average,stagger ratio and high altitude enclosure ratio as three possible pertinent parameters.This thesis study about the height parameters and its wind environment through several times adjusting and simulating height parameters to the large scale urban area type-unit wind environment.Apart from quantitative study,the relationship between large scale urban area height distribution structure and its type wind field.The optimizing wind environment oriented urban height controlling tactic is provided qualitatively and quantitatively and the urban planning practical existed height controlling system is perfected.Lastly,the height controlling optimization technic and tactic is adopted to have a practical optimization research on Da Lian Zhongshan square area.The valuable explorer is expected in an aspect of urban wind environment improved by building height controlling.
