“…The present results, combined with the results of our previous studies [17,20], can provide the basic data required to comprehensively estimate the potential C and N sequestration in soils that would result from the restoration of severely desertified sandy land through tree and shrub planting as well as grazing exclosures.…”

“…The region has a continental semiarid monsoon temperate climate regime, with a mean annual precipitation of 366 mm, of which 70% falls from June to August, a mean annual potential evaporation of 1935 mm, and a mean annual air temperature of 6.8 • C. Mean monthly temperatures range from a minimum of −13.2 • C in January to a maximum of 23.5 • C in July. The mean wind speed is 4.3 m·s −1 , with occasional occurrences of gales ≥20 m·s −1 in winter and spring, when the vegetation cover is lowest and the soil is driest [17]. The area's soils are derived from alluvial and aeolian sediments, and have been classified as Cambic Arenosols [28], with a coarse texture (medium to coarse sand) and a loose structure.…”

“…However, almost 80% of this region has suffered from desertification since the 1950s, primarily due to the region's fragile ecology combined with climate change and inappropriate anthropogenic activities such as overgrazing, excessive cultivation of marginal farmland, firewood harvesting, and excessive groundwater withdrawal [17]. The landscape became dominated by active dunes (Figure 1a) by the late 1970s, and local people live in poverty due to the severe environmental degradation in the region.…”

Caragana microphylla, a native perennial leguminous shrub, is widely used for desertification control in China's Horqin Sandy Land. We investigated the effects of afforestation using C. microphylla in areas with fixed and active dunes on soil carbon (C) and nitrogen (N) storage in the soil total and light-fraction (LF) organic matter. Compared to the values in the control areas, soil organic carbon (SOC) storage to a depth of 100 cm increased by 88%, 74%, and 145% at 9, 15, and 31 years after shrub planting, respectively; the corresponding values were 68%, 61%, and 195% for total nitrogen (TN) storage, 109%, 199%, and 202% for LF organic carbon storage, and 203%, 337%, and 342% for LF nitrogen storage. The soil light-fraction (LF) organic matter contributed significantly to total SOC and TN storage, despite the low proportion of total soil mass accounted for by the LF dry matter. Thus, afforestation using C. microphylla was an effective way to sequester C and to restore degraded soils, but the process was slow; it would take more than 100 years to fully restore SOC storage in active dunes through afforestation with C. microphylla in the Horqin Sandy Land.

“…One method to fix sand dunes consists in afforestation (Li et al 2010). This action not only increased plant coverage and soil nitrogen (N), but also may sequester atmospheric carbon (C) dioxide (Hu et al 2015, Li et al 2013. Moreover, vegetation cover of sand dunes has been reported to increase soil moisture (Li et al 2007) and soil nutrients (Niu et al 2015) and to restore plant diversity (Bremer & Farley 2010).…”

Prosopis juliflora is one of the suitable tree species used as vegetation cover for sand dunes fixation. The objectives of this study were to determine the effect of P. juliflora afforestation and its canopy coverage classes on soil carbon (C) stock and nutrient status in sand dunes after 22 years since afforestation. We hypothesized that increasing the canopy coverage would result in higher soil C stocks and nutrient content. We selected two 10-ha afforested sand dunes with 25-50% and more than 75% canopy coverage, respectively, and a 10-ha non-afforested dune (control). At each site, 15 soil samples were taken at two depths (0-5 cm and 5-50 cm). The results indicated a strong increase in the topsoil C stock (from 0.54 to 4.49 tC ha -1 in control and afforested sites, respectively), while a lower change in subsoil C stock was detected (3.0 and 4.6 tC ha -1 in control and afforested sites, respectively). Although, different canopy classes resulted in no significant differences in soil C stock, significant differences were observed for all the soil physico-chemical properties that were studied.

The progressively restoration of degraded vegetation in semiarid and arid desertified areas undoubtedly formed different habitat types. The most plants regulate their growth by fixing carbon with their energy deriving from photosynthesis; carbon (C) and nitrogen (N) play the crucial role in regulating plant growth, community structure, and function in the vegetation restoration progress. However, it is still unclear how habitat types affect the dynamic changes in allocation in C and N storage of vegetation–soil system in sandy grasslands. Here, we investigated plant community characteristics and soil properties across three successional stages of habitat types: semi‐fixed dunes (SFD), fixed dunes (FD), and grasslands (G) in 2011, 2013, and 2015. We also examined the C and N concentrations of vegetation–soil system and estimated their C and N storage. The C and N storage of vegetation system, soil, and vegetation–soil system remarkably increased from SFD to G. The litter C and N storage in SFD, N storage of vegetation system in SFD, and N storage of soil and vegetation–soil system in FD increased from 2011 to 2015, while aboveground plant C and N storage of FD were higher in 2011 than in 2013 and 2015. Most of C and N were sequestered in soil in the vegetation restoration progress. These results suggest that the dynamic changes in allocation in C and N storage in vegetation–soil systems varied with habitat types. Our study highlights that SFD has higher N sequestration rate in vegetation, while FD has the considerably N sequestration rate in the soil.
