“…The restoration of degraded sandy areas should be based on vegetation restoration while relevant techniques from other fields should also be applied scientifically and reasonably. Second, the restoration of the soil components of degraded sandy ecosystems should be strengthened [48]. As the ecological restoration of soil takes a relatively long time, attention can be paid to the establishment of microbial populations in the soil in the future to accelerate the directional cultivation of soil [49].…”

As one of the countries with the highest desertification in the world, sand ecological restoration and management have been given great attention in China. However, a systematic and comprehensive review of sand-restoration technology is still lacking. Therefore, with “sand restoration technology” and “China” as the keywords, we reviewed 226 English articles and 512 Chinese articles based on the Web of Science and China National Knowledge Infrastructure data sources from 1990 to 2021. The results showed that (1) The number of published articles about sand-restoration technology increased during the last 30 years, experiencing a slow–fast–steady growth process. (2) The analysis of keyword hotspots showed that the literature focuses on restoration, Maowusu sandy land, vegetation restoration, sand barrier, governance model, etc. (3) Biological restoration techniques are dominant among sand-restoration techniques and are mainly carried out through plant and physical technology. (4) Composite sand-restoration technology, including arbors, shrubs, grass, and soil, is a progressive research topic for the future. By installing an incorporated device for sand-restoration generation, we offer a theoretical foundation for strengthening sand-restoration generation in China and beyond.

“…Sand-stabilizing techniques such as the use of soil amendments and tackifiers have often been used with biocrust inoculation to assist biocrust colonization [ 8 – 11 ]. Successful biocrust inoculation depends on the combination of biocrust species and the supporting substrate [ 9 ].…”

Biocrust inoculation and microbially induced carbonate precipitation (MICP) are tools used in restoring degraded arid lands. It remains unclear whether the ecological functions of the two tools persist when these methods are combined and subjected to freeze–thaw (FT) cycles. We hypothesized a synergetic interaction between MICP treatment and biocrust under FT cycles, which would allow both components to retain their ecological functions. We grew cyanobacterial (Nostoc commune) biocrusts on bare soil and on MICP (Sporosarcina pasteurii)-treated soil, subjecting them to repeated FT cycles simulating the Mongolian climate. Generalized linear modeling revealed that FT cycling did not affect physical structure or related functions but could increase the productivity and reduce the nutrient condition of the crust. The results confirm the high tolerance of MICP-treated soil and biocrust to FT cycling. MICP treatment + biocrust maintained higher total carbohydrate content under FT stress. Our study indicates that biocrust on biomineralized soil has a robust enough structure to endure FT cycling during spring and autumn and to promote restoration of degraded lands.
