不同临街空间模式对小气候环境的影响——以北京市城区典型临街空间为例

Influences on microclimate environment by different street space modes:taking Beijing's typical urban street space for example

选取北京城区典型临街空间作为实测对象,在夏季6-7月份,利用HOBO便携式气象站对临街空间的温度、相对湿度、风速、大气压力和太阳辐射等小气候指标进行了测量记录。通过分析对比不同临街空间模式(建筑高度、绿地形态与面积、断面构成等不同要素)对小气候的影响和调节作用,揭示了小气候环境各项指标之间的关联性。在此基础上,对未来城市街道空间小气候环境的改善提出了建议。

This essay takes Beijing typical public street spaces as objects to measure and record temperature, relative humidity, wind speed, barometric pressure and solar radiation with a HOBO portable weather station in June and July in the summer. By analyzing and comparing regulating ability of microclimate in different models of street space （different elements such as building height, green space form and area and composition of sections） , it reveals the linkage of microclimate environment indicators. Then it puts forward some suggestions in im- provement of microclimate environment.
