Abstract  Aeolian desertification and climate change are two hotspots people are facing today. Much attention is paid on the feedback loops between them two. Deterioration of climate conditions, continuous desiccation for instance, can lead to aeolian desertification, and aeolian desertification can give a negative reaction to climate change through biogeophysical feedback, releasing more dust aerosol and increasing greenhouse gases concentration. In local areas, this kind of interaction may come into being positive loops, allowing the disturbance to be amplified. Based on the analysis of a large amount of literatures, the authors reviewed the existing research systematically through analyzing the feedback loops between climate change and biogeophysical feedback mechanism, dust aerosol and greenhouse gases. There are four bottlenecks in the research: ①the scale that biogeophysical feedback mechanism takes effect; ②causality between dust aerosol and precipitation; ③disagreement of the data used and the differences of their characters; ④methods to distinguish the human-induced and natural factors that lead to aeolian desertification. The authors claim that scientists should study the interactions between aeolian desertification and climate change systematically in earth system science terms, and pay more attention on both model research and field observation.
Key words:  aeolian desertification      climate change      biogeophysical mechanism
