摘要： The aim of this study was to discuss the spectral response of the wheat to different stresses between in-situ canopy reflectance and multiband satellite image reflectance. In the three critical growing stages of winter wheat, the field investigations and spectral measurements were conducted and the Landsat 5 TM images were also acquired synchronously to monitor winter wheat under conditions of stripe rust stress and water stress and normal condition. By the comparison of the reflectance between in-situ canopy and images within three treatments, it was concluded that the spectral response of stressed wheat and healthy wheat was consistent in field and satellite remote sensing among the three critical growing stages. The study will lay a theoretical basis on monitoring and identifying the stressed wheat in the large area.
