中文摘要	应用高学谱遥感技术荒漠化进行监测的过程中，重建地物光谱是一项关键性的术。在图像预处理及光谱重采样的基础上，通过严格模拟大气辐射过程。推导并选用一元线性模型来重建荒漠化地区地物光谱，获得了满意的结果，为目标地物直物直接识别及其信息的定量反演奠定了基础
英文摘要	spectral resolution is the main characteristic of hyper-spectral remote sensing, it provide a possibility for us to directly abstract continuous spectrum curve of objects from image and to discern them by spectral match. However, before spectral re-building, the spectrum which abstracted directly from image can not represent the true characteristic of objects. So, the main purpose of this study is to develop a simple and useful model in order to re-build spectrum for hyper-spectral remote sensing in desertification monitoring, it is also a key technique in the application of hyper-spectral remote sensing. Based on the preprocessing of hyper-spectral resolution data of desertification areas and spectral re-sampling, through simulating the procedure of atmospheric radiation, a linear model was developed and applied in this paper to re-build spectrum and got some satisfactory results, the correlation between re-built spectrums and true spectrums is high. The research results showed that the linear has better practicality, it lay a better foundation for improving the precision of objection interpreting and quantitatively retrieves of information.
