针对中国人多地碎的特点 ,将AVHRR图像和高空间分辨率图像配准 ,利用一种气象 遥感综合模型分别计算AVHRR像元整体及对应高分辨率图像中作物区的蒸散 ,给出两者之间的差异 ,分析并检验利用AVHRR图像计算大区域蒸散中由非单一地表产生的误差 ,并给出一种适用于所研究区域的相应的统计订正方法。
Aiming at the characteristics of multi-ground broken Chinese, the AVHRR image and the high spatial resolution image are registered, and the evapotranspiration of the whole crop of AVHRR pixels and the corresponding high-resolution image is calculated respectively by using a comprehensive model of meteorological remote sensing. , The error caused by non-unitary surface in large area evapotranspiration was analyzed and tested by using AVHRR images, and a corresponding statistical correction method suitable for the studied area was given.
