Abstract: Land desertification is becoming more and more serious, while its reversal is of ecological, economic, and social significances. In some revegetated regions, mobile sand dunes have been successfully transformed into stable and productive ecosystems, and the structure and function of the revegetated ecosystems have changed considerably. Based on the related researches, this paper summarized the changes of soil physical properties (water-holding capacity, mechanical composition, and structure, etc.), chemical properties (carbon, nitrogen, and phosphorus, etc.), and biological properties (microbial biomass, respiration, and enzyme activities, etc.) during the reversal of desertification, aimed to elucid
ate the responses of soil properties to desertification reversal. Some suggestions for further researches in this field, e.g., the studies on soil quality change by microorganism community, and the roles of functional microorganisms in soil evolvement, were put forward, aimed to promote the research on the biological properties of desertified soil during the process of reversal.
