夏季下垫面材质类型与颜色表面温度热环境关系研究

Study on the Relationship between the Type of Underlying Surface Material and Color Surface Temperature and Thermal Environment in Summer

随着近些年来城市热岛问题的日益突出,城市下垫面对人室外热环境感受上有着显著的影响。城市下垫面铺装材质,其表面温度通过对流和辐射等方式,加热材质上方空气,影响城市热环境。为此,选取8种不同材质下垫面,以及10种相同材质不同颜色作为研究对象。利于红外热像法测量材质表面温度,进而分析各种类型材质,以及颜色对城市热环境的关系和影响。

As the problems in the research of urban heat island have become increasingly prominent in recent years,the urban underlay has a significant impact on the perception of the outdoor thermal environment.The surface temperature of the urban underlying surface paving material heats the air above the material through convection and radiation,and affects the urban thermal environment.For this reason,8 kinds of underlay surfaces of different materials and 10 kinds of the same material with different colors are selected as the research objects.It is helpful to measure the surface temperature of materials by infrared thermal imaging and analyze the relationship and influence of various types of materials and colors on the urban thermal environment.
