基于TM图像反演垦利县地表温度

Retrieving land surface temperature-based on TM data from Kenli County,Shandong Province

利用垦利县TM/ETM+图像的热红外波段数据,结合辐射传输方程和覃志豪单窗算法等算法反演垦利县地表温度,讨论了各种温度反演算法精度、土地利用类型的变化与相应地表温度的变化.结果表明:覃志豪单窗算法的精度最高,垦利县两年间各地类地表温度基本保持不变或仅有较小变化.

Focusing on the theories and methods of retrieving land surface temperature and land use/cover change, which summarized five popular algorithms for retrieving LST from Landsat TM/ETM＋ Thermal Infrared Band data, the paper discussed the precision of mono-windows of algorithmvarious temperatures, the changes in land use types and relevant land surface temperatures in theregion studied. The results indicated that Qin＇s mono-window algorithm has the highest precision and that the average urban surface temperature changes are not significant.
