The negative correlation of the soil spectral reflectance and SOM content, spectral reflectance characteristics of different components of soil organic matter were reviewed and hyperspectral forecast research on SOM content. The current study of existing problems was analyzed with emphasis on the lack of evaluation of the model based on a variety of soil. The direction of the land-based species of the establishment of SOM model for the evaluation was pointed out, new prospects on the use of hyperspectral technology to explain the s...
