| 摘 要： | 基于普适性单通道算法，利用2005年5月6日的TM数据反演北京市区的实际地表温度。在此基础上，分析了北京市区的热环境特征、热岛分布的位置。运用GIS空间分析工具，分析了地表温度与地形特征和地表覆盖类型之间的关系。结果表明，北京市热岛分布具有环状和带状分布特征，高程较低处和坡度较小处更容易形成热岛中心，不同地表覆盖类型的热特征具有显著的差异。

| Abstract: | Land surface temperature of Beijing city was retrieved based on the TM imagery data acquired on May 6th 2005 with the generalized single-channel algorithm. The characteristics of the thermal environment and the distribution of the urban heat island of Beijing city were addressed. The relationships between topographic factors, various land cover types and the land surface temperature were analyzed using GIS spatial analysis tools. The results show that the urban heat island area of Beijing city is strip-shaped and ring-shaped. Lower elevation and smaller slope are favorable to form the urban heat island, and the various land cover types have dramatically different thermal properties. |
