| 摘 要： | 以贵州省黎平县山地植被覆盖区为例，基于ASTER遥感数据进行15 m分辨率的归一化植被指数制图和地表发射率制图，在利用MODTRAN 4大气辐射传输模型进行大气订正的基础上，基于普朗克辐射方程的推导反演陆表温度，取得了较为理想的结果。

| Abstract: | This research was performed in Liping County, Guizhou Province, a typical mountain area covered by vegetation in southern China. Having classified land surface objects based on the Normalized Difference Vegetation Index (NDVI) map compiled from ASTER data, the authors assumed different emissivities for different objects and made scale conversion to 90 meter resolution, thus compiling the emissivity map of the study area. Then the radiance of the study area was obtained through the thermal infrared bands of ASTER which was atmospherically corrected by MODTRAN 4. At last, the authors retrieved the land surface temperature based on the Plank radiate deduction equation and acquired good results. |
