摘要: 利用FY-1D/AVHRR数据通道1、2的反射率计算植被指数和通道4、5的亮温计算作物冠层温度,进而求出植被供水指数来监测干旱状况。文章简单介绍利用植被供水指数法在内蒙古干旱监测中的应用。结果表明,植被供水指数法适用于内蒙古地区生长季大范围的干旱监测。

Abstract: The vegetation index and crop canopy temperature were calculated respectively by using reflectance of FY-1D/AVHRR Data Channel 1 and 2 and brightness temperature of Data Channel 4 and 5,moreover,vegetation supply water index was calculated to monitor drought condition.The article had introduced sententiously the method that vegetation supply water index to monitor drought condition in Inner Mongolian. It showed that method of vegetation supply water index is fit for drought monitoring during vegetate stage in large scale.
