Deserts and sandy land in northern China are very susceptible to sandy desertification and are the main source of sand-dust storms of Asian dust. However, because of the complex factors involved, descriptions of the relationship between sandy desertification and surface characteristics in these regions are lacking. We monitored the surface characteristics and their changes in time using information...
Most remote sensing studies assess the desertification using vegetation monitoring method. But it has the insufficient precision of vegetation monitoring for the limited vegetation cover of the desertification region. Therefore, it offers an alternative approach for the desertification research to assess sand dune and sandy land change using remote sensing in the desertification region. In this study,...
The differences of surface characteristics are very important for sand dune stabilization, sand dune migration, sand transport and dust storm outburst which have been the focus of many researches interest. In this study, a new method for surface characteristic assessment on a regional scale was developed using a Decision Tree approach based on combination the TCA and DI with the TGSI derived from...
