摘要(Abstract)：

针对高分一号影像在参考蒸散发遥感反演中应用较少的问题,该文基于国产16m分辨率的高分一号多光谱影像及Landsat8影像及对应时间气象数据,采用国际上应用较广的FAO-PM模型、Priestley-Taylor模型两种方法,对2014年5月6日邯郸市研究区域内的参考蒸散发量(ET_0)进行了反演,并与只采用Landsat8影像与气象数据反演的结果进行了对比分析。结果表明,高分影像结合Landsat8影像反演的参考蒸散发结果与仅利用Landsat8影像反演的结果具有高度的线性相关性,该方法将在小区域范围内的蒸散反演具有更高的空间分辨率。实验结果证实了高分一号影像与Landsat8联合进行蒸散发反演的可行性。
