| 摘 要： | 采用Landsat ETM＋影像数据，分别利用MODTRAN4和FLAASH对热红外波段和可见光、近红外波段进行大气校正，采用Valor的植被指数混合模型估算地表比辐射率，以普朗克公式推算地表温度，并以长沙市为研究区，分析了不同地表覆盖类型以及NDVI与地表温度之间的关系。结果表明，不同地表覆盖类型的地表温度有着显著差异，城市地表温度与NDVI之间具有明显的负相关关系，增加城市的绿地面积有助于缓解城市热岛效应。

| Abstract: | The thermal infrared band and the red and near infrared bands of Landsat ETM+data were atmospherically corrected by MODTRAN 4 and FLAASH,and land surface emissivity was calculated by combining vegetation index algorithm from Valor.The land surface temperature was retrieved based on inversion of the Plank' s law.And this method was applied to Changsha city,the relationship between urban land cover and land surface temperature were studied,and the same work was done between NDVI and land surface temperature.T... |
