Abstract The sandy desertification assessment is an important basic work on which the desert control project is
based. The present assessment method mainly depends on ground survey combined with optical interpretation of TM
images. This needs considerable funds and a long period,and hence cannot meet the demands of desert control work.
Remote senseing data were used in this paper to retrieve the factors of sandy desertification assessment based on
the linear regression model. The ground survey criteria were employed in the remote sensing model. These measures
are useful in applying remote senseing data to rapid and effective assessment of sandy desertification.
