| Abstract: | Experiments in Aibi lake area were made in order to compare the difference in soil erosion model between vegetation index and vegetation coverage obtained by linear spectral unmixing. The results of the experiment indicate that vegetation coverage is more suitable for soil erosion model. |

| Keywords: | soil erosion vegetation coverage vegetation index linear spectral unmixing |
