英文摘要： Xinjiang production and construction corps precision agriculture in the process of gradually realize informatization, digitization, an urgent need to quickly by remote sensing monitoring method for large area of red jujube quality. This project in southern xinjiang red jujube comprehensive digital model work, based on the two to explore polarization reflection characteristics to improve spectral resolution to improve the precision of remote sensing detection method. Experiments for jujube multi-angle polarization information and 2 to the reflection characteristics of the target spectrum, through the red jujube quality component spectra and the conditions of the field of zaoyuan canopy spectral statistical studies. In southern xinjiang red jujube multi-angle polarized light detection experiments, studies the changing rule of the red jujube reflex polarized direction information and detecting method. Use the combination of indoor and outdoor spectroscopy method, carry out quality and jujube jujube leaf spectra and jujube canopy spectral correlation research. In 224 and 14 NongYiShi 10 group two different geographical composition spectrum of red jujube jujube canopy spectral characteristics research and field conditions. Response spectrum and polarization and to explore the southern xinjiang red jujube reflection spectrum corresponding relation, according to the characteristics of southern xinjiang red jujube choose the best sampling method to build more optical parameters of polarization remote sensing database model, combined with the corresponding regional traffic for the research of polarization remote sensing monitoring models and mechanism. In southern xinjiang red jujube quality remote sensing monitoring for the future lay a theoretical foundation.
