Abstract

While studying the vegetation degradation, Vegetation coverage percentage is often used. In the field of remote sensing, using vegetation index (NDVI, MSAVI, etc.) to descript vegetation coverage percentage is popular accepted and applied. In this paper, experiments in Aibi lake area were made in order to compare the difference between NDV, MSAVI and Vegetation coverage obtained by linear spectral unmixing. The results of the experiment indicate that vegetation coverage is more suitable for monitoring low vegetation cover dynamic change.
