The research of remote sensing monitoring of land desertification were summarized and prospected. And pointed out that by strengthening variety of desertification land classification index system construction,improve the monitoring accuracy,and constantly explore new ways and methods of applicability,clear macro technical route and process of remote sensing monitoring of desertification,in-depth analysis to carry out the causes and influence factors,and make full use of multi-source and several aspects,such as a variety of data information can be continuously to improve the land desertification remote sensing monitoring technology. On the one hand can provide scientific basis for the decision-making departments,improve the governance and desertification area ecological environment restoration and reconstruction of the decision-making level and governance effect; On the other hand, can be the researches on the mechanism of the desertification process,sandy desertification influence on regional and global climate change research,and thus contribute to the global change research.
