基于 Landsat 8的城市热岛效应研究初探--以厦门市为例

摘要

以厦门市为研究区域，以2013年的Landsat 8为研究数据，研究亮度温度反演和地表温度反演算法，通过ENVI/IDL软件编程实现，并且利用厦门市气象局实测温度验证地表反演结果的有效性。同时，还分析了当前厦门市热岛效应空间分布情况，以期为厦门市城市规划和建设旅行城市等工作提供重要参考意义。%Taking Xiamen as the study area and Landsat 8 in 2013 as the research data , the paper studies on algorithms of brightness temperature inversion and land surface temperature inversion , programs and implements with the ENVI/IDL software, verifies the ef-fectiveness of the surface inversion results by using the measured temperature from Xiamen Bureau of Meteorology , as well as analyzes the spatial distribution of heat island effect in Xiamen in order to provide important reference for city planning and travel city construc -tion.
