Research On The Influence Of Spatial Features Of Urban Streets On Microclimate

With the rapid development of economy,the building area in the city is continuously enlarged,and the space of public comfortable environment in the city is shrinking constantly,which leads to the huge problem of urban living environment.Urban street space is an important part of urban public space,which is closely related to social needs and the needs of the public itself.Research on city streets microclimate can further understand the impact of urban street space for the environment microclimate,through to the corresponding actual measure microclimate factors can provide favorable data support for improving the street environment.It is an inevitable choice for the sustainable development of the city to improve the microclimate of urban streets.Based on the characteristics of the urban climate in Luoyang,this paper makes a practical analysis on the microclimatic factors of the three seasons of the urban street space in Luoyang.The study selected four measurement objects,namely,Xiyuan Road,Zhongzhou West Road,Jinghua Road and YTO square which located at the junction of Changan Road and Jianshe Road in Luoyang city.In addition,the microclimate measurement of the measurement object is mainly composed of temperature and humidity,average wind speed,dew point temperature,wet bulb temperature and so on.In measuring the microclimate data obtained after the corresponding calculation and analysis,there are some following conclusions:(1)Xiyuan Road is relatively comfortable measurement object of all the city streets,mainly manifested in the average temperature in summer is lower than other measurement streets 2 °C ~ 4 °C,and in witer,the average temperature is higher than other streets 3 °C ~ 4 °C.(2)There are differences in the environment of microclimate in different locations in the street space,and it changes with the different location of the measuring points.(3)There are differences in the microclimatic environment between different street spaces,with the most obvious difference between the vegetated street and the unvegetated street.According to the differences different street spaces,this thesis focuses on surveying the problems in the street space and providing strategic suggestions about improving the street space microclimate environment to solve these problems.In the meantime,the results provide theoretical supports for creating a comfortable outdoor public environment in the future and application value for future related microclimate research.
