摘　　要：建筑物表面朝向及材料的不同使其表面温度差异很大。测量了合肥市建筑物不同方位、不同壁面(石灰、水泥、红砖、瓷砖)以及相关背景(草地、树木、水泥路面、柏油路面、水面)的温度,得出了建筑物不同朝向及不同背景的温度分布特征以及在一天内随时间的温度变化规律。建立了温度计算模型并通过MATLAB模拟计算了建筑物及部分背景的温度,通过该模型计算讨论了空气温度、大气透明度、风速以及地面湿度等参数对建筑物表面和背景温度的影响。Building surfaces temperature differs greatly due to different orientations and materials. Temperature of buildings with different orientations and materials （lime, cement, red brick, ceramic tile） and relevant backgrounds （grassland, trees, cement pavement, sphalt pavement and water） were measured in Hefei city. Temperature distribution of building of different orientations, backgrounds and its variation with different time of the day was obtained. Temperature calculation model was developed. Besides, The temperatures of the building and some backgrounds were calculated by MATLAB. Finally, influence of air temperature, atmospheric transmittance, wind speed and surface humidity on building surface and background temperature were investigated by model tests.
