基于Landsat TM遥感数据的城市热岛效应信息提取与分析

The Retrieval of and Analysis on the Urban Heat Island Effect Based on Landsat TM Remote Sensing Data

在一定数量文献的基础上,概括了基于Landsat TM遥感数据的城市热岛效应信息提取方法以及对反演的地表温度的分析方法,温度反演方法有大气校正法、单窗算法、单通道算法,指出利用城市热岛信息,可以分析城市下垫面热岛的空间分布和结构特征、热岛的时间演化特点以及各种可能的驱动因素等。

Based on a certain amount of literatures, this paper sums up the methods for retrieving information of the urban heat island effect based on landsat TM remote sensing data and the methods for analyzing the inversed surface temperature including the atmospheric correction method, single-channel method and mono-window algorithm, and points out that making use of the information of the urban heat island effect can analyze the spatial distribution and structural features of the heat island on urban underlying surface, the time evolution features of the heat island, and various possible driving factors, etc.
