“…This result was the same as that found in the previous studies in which field conditions and landscape background influenced the successional process of vegetation (Johnson & Miyanishi, 2008), especially during the early stage of succession (van Hall, Cammeraat, Keesstra, & Zorn, 2016). As plant species coverage changes, the importance of the landscape environment increased gradually (Liu et al, 2017; van Hall et al, 2016). Changes in the landscape pattern have significant effects on the evolution of soil properties and habitat conditions (Kovář, Štefánek, & Mrázek, 2011; Tulloch et al, 2018).…”

“…Previous studies have shown that afforestation not only improves the soil environment (Zhao et al, 2017), including soil nutrients, moisture, and structure (Deng, Kim, Peng, & Shangguan, 2018; Xiao et al, 2017; Zhang, An, Cai, Guo, & Xiao, 2017; Zhu, Deng, Zhang, & Shangguan, 2016) of plants, but also significantly influences plant diversity (Abella, 2010; Díaz‐García, Pineda, López‐Barrera, & Moreno, 2017; Laughlin et al, 2017; Xiao et al, 2017) and ecosystem productivity (Uthappa et al, 2018). Many studies have also reported that soil nutrients such as nitrogen and phosphorus are important factors affecting vegetation coverage, plant community composition, and plant diversity (Chen et al, 2017; Liu, Xing, & Yang, 2017; Sanaei, Ali, & Chahouki, 2018; Seabloom et al, 2017; Song, Liu, Wu, Gao, & Hao, 2018; Wei et al, 2017; Zhu, Tang, Shangguan, & Deng, 2018). Competition for soil resources, especially nitrogen, leads to spatial heterogeneity in communities and there is a relationship between competition and coexistence within plant communities (Tilman, 1982, 1985).…”

Vegetation restoration has been proposed as an effective measure for rehabilitating degraded land and slowing desertification in arid regions. However, the spatial variation in soil quality and plant diversity following vegetation restoration remains unclear. This study was designed to explore soil nutrient dynamics and how soil nutrients affect plant diversity and spatial heterogeneity after shrub restoration. We assessed the effect of Haloxylon ammodendron (C.A.Mey.) Bunge (which has been planted over 30 years) on the soil nutrients and plant diversity in a desert–oasis ecotone in Minqin County, Gansu, China, using geostatistics, beta diversity and rarefaction analyses, and Hill number extrapolation. Soil nutrients, including soil organic matter, total nitrogen, and alkali nitrogen, increased significantly after H. ammodendron planting. Species richness gradually increased from 1–5 years to 10–20 years after H. ammodendron was planted but then decreased at 20–30 years. The largest differences in plant composition were observed at 15 and 20 years. Plant diversity increased in the whole 30 years after shrub planting, increasing in the first 25 years and then decreasing at 26–30 year stage. The maximum coefficient of determination for the spatial heterogeneity model fit was 0.84 (25 years). The spatial heterogeneity in vegetation decreased with increasing soil available K content at 1–10 years. Our results suggest that planting shrubs can improve soil conditions and plant species diversity in desert–oasis ecotones and soil nutrients have a strong influence on plant diversity patterns and spatial heterogeneity following vegetation restoration.

“…They enhance nutrient levels by carbon (C) sequestration Chamizo (2017) and nitrogen (N) fixation (Weber et al, 2016). Biocrusts can also ameliorate climate change, regulate the hydrologic cycles (such as partitioning rainfall between infiltration and runoff), reduce soil erosion, and increase soil biodiversity (i.e., microorganisms and arthropods) by providing abundant nutrients and creating suitable micro‐environments (Eldridge et al, 2020; Liu et al, 2017) in desert ecosystems.…”

“…They improve soil particle cohesion and surface structure (Williams et al, 2019), regulate moisture and temperature, and control biogeochemical cycles (Čapek et al, 2021). In turn, biocrusts directly provide organic nutrients as substrates and suitable microclimate for soil microorganisms (Liu et al, 2017). The coevolution pattern between biocrusts and microbes is commonly accepted in desert ecosystems (Lan et al, 2015).…”

Sand burial of crusts, caused by ant burrowing, is a common phenomenon in desert landscapes, yet the potential impacts on soil processes are unknown. Three sand burial depths, 3.0-5.0 mm (deep burial), 1.0-1.5 mm (shallow burial), and 0 mm (control) affecting two dominant biocrusts (viz., cyanobacteria-lichen crusts and moss crusts) sampled in the moist and dry seasons were selected to explore this issue in two vegetation areas of the Tennger Desert. We collected 180 samples from biocrust layers and topsoil to assess soil physicochemical properties, microbial biomass, basal respiration, and enzymes activities. The results showed that sand burial of crusts reduced soil microbial biomass, basal respiration, and enzyme activities, while deep burial caused a substantial decline in these parameters. Sand burial interfered with the biocrusts structure (e.g., rupture and flaking) and properties, subsequently causing soil-nutrient deprivation and soil microclimate deterioration. These are major mechanisms for decreasing soil microbial biomass, basal respiration, and enzyme activities.Moss crusts had significantly higher levels of the microbial parameters than cyanobacteria-lichen crusts following sand burial, indicating that biocrusts' tolerance to sand burial was synchronized with their progressive succession. In addition, soil microbial parameters were higher in natural vegetation areas than artificial vegetation areas following sand burial. Such observations suggest that high soil fertility could mitigate the negative effects of sand burial on soil processes. In conclusion, sand burial induces biocrust degradation and further disturbs surface soil processes in arid desert ecosystems.
