| 摘 要： | 主要研究利用Landsat TM6热红外波段遥感数据定量反演林地温度的方法与可行性.首先计算了研究区的比值植被指数(RVI),然后利用单窗算法开展林地温度反演,建立起了林地温度与比值植被指数之间的相关关系.研究结果表明:利用单窗算法反演的林地温度精度较高;林地温度与比值植被指数(RVI)之间存在着密切的负相关关系,林地温度与林冠变化之间关系十分密切.

| Abstract: | A methodology to quantitatively extract forest land temperature from TM6 thermal in-frared remote sensing data is studied and discussed in this paper.The ratio vegetation index(RVI) of the study area is calculated first,the forest land temperature is computed with the mono-window algorithm after,and the correlation between the forest land temperature and the ratio vegetation index is then built.The result showed that the forest land temperature by using the mono-window algorithm has a high accuracy.The corr... |
