摘 要: 利用PROBA卫星高光谱传感器(compact high resolution imaging spectrometer, CHRIS)遥感影像对北京城市建筑材质和自然地表进行分层分类提取,并与Landsat 5专题制图仪(thematic mapper, TM)热红外数据反演得到的北京城市地表温度相结合,定量分析主要建筑材质、自然地类与地表温度的关系,并重点就不同建筑材质对城市热岛(urban heat island, UHI)的影响及影响因素进行了分析。结果表明:北京城区中的砖瓦房表面温度最高,比其他材质高1.6~3.6 K,比自然地表高6.0~8.3 K;金属合金、混凝土、水泥和沥青的平均温度相当,比砖瓦略低;城市中的玻璃幕墙能够有效降低表面温度,比其他材质低2.4~3.2 K.
关 键 词: 地理信息系统;遥感;城市热岛;建筑材质;地表温度;高光谱传感器数据;TM数据

Abstract: PROBA compact high resolution imaging spectrometer (CHRIS) hyperspectral image is used to extract building materials and natural surfaces based on a hierarchical classification method in Beijing. In this study, the relationships between building materials in the urban area and land surface temperature are quantitatively analyzed by combining with land surface temperature in Beijing retrieved by thermal infrared data of Landsat 5 thematic mapper (TM), and the influence on urban heat island (UHI) leaded by different materials and the influencing factors are discussed. The results indicate that the brick and tile-roof buildings have the highest temperature, and are about 1.6~3.6 K higher than the other building materials, 6.0~8.3 K higher than natural surfaces; metal surface, concrete, cement and asphalt have nearly the similar surface average temperature and lower than brick and tile; the glass curtain wall can reduce the surface temperature effectively and is about 2.4~3.2 K lower than the others.
Key words: geographic information system; remote sensing; urban heat island; building materials; land surface temperature; compact high resolution imaging spectrometer data; TM data
