| Abstract: | The negative correlation of the soil spectral reflectance and SOM content,spectral reflectance character-istics of different components of soil organic matter were reviewed and hyperspectral forecast research on SOM con-tent.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 tech... |
