“…This could be attributed to the root of shrubs dominated by legumes which excrete a high amount of sugars, amino acids and other low-molecular-weight organic compounds. These compounds can positively affect microbial growth [39]. Shrubs dominated by legumes could be recommended for reclamation of reconstructed soil in mining areas on the Loess Plateau.…”

Soil microbes are the main driving forces and influencing factors of biochemical reactions in the environment. Study of ecological recovery after mining activities has prompted wider recognition of the importance of microbial diversity to ecosystem recovery; however, the response of soil bacterial communities to vegetation restoration types and soil biochemical properties remains poorly understood. The purpose of this research was to explore the soil bacterial communities and soil biochemical properties at four sampling sites (brushland (BL), forestland (FL), grassland (GL) and unreclaimed land (UL)) on the Loess Plateau, China, to evaluate the effect of vegetation restoration on the reconstructed soil in mining areas. In August 2017, samples were collected at the Heidaigou coal mine dumps. Illumina MiSeq sequencing was used to identify the structure of the soil bacterial community and evaluate its relationships with soil biochemical properties. The results showed that soil biochemical properties (soil organic matter, available phosphorus, urease, sucrase, microbial biomass carbon and microbial biomass nitrogen) were significantly increased in BL, FL and GL relative to UL, indicating that the soil quality was significantly improved by vegetation restoration. In addition, the results showed that the vegetation restoration on the reconstructed soil in the mining area could significantly improve the operational taxonomic units (OTUs), abundance (ACE and Chao1) and diversity (Shannon and Simpson) indices of bacterial community and the dominant phyla were Proteobacteria, Actinobacteria and Acidobacteria. With vegetation restoration, the relative abundance of Proteobacteria and Acidobacteria showed an increasing trend, while that of Actinobacteria showed a decreasing trend, and the dominant phyla were only significantly correlated with a few biochemical properties. Moreover, there were no changes in soil bacterial community structures across the four sampling sites and the response of the bacterial community to biochemical properties was not obvious. This implies that, although the region has experienced about 20 years of vegetation restoration, the microbial community still maintains good stability and lagging response to soil biochemical properties. Since the BL soil had better biochemical properties and higher bacterial richness and diversity, it was recommended as the optimum vegetation restoration type for soil reclamation in this area.

“…Leguminous shrub, as nurse plants (Padilla & Pugnaire, 2006), facilitates the growth of understory plants, leading to the development of a community consisting of numerous small shrubs and herbaceous species (Marquez & Allen, 1996). Grass-legume led to the recovery of labile soil fertility and plant nitrogen (Robles & Burke, 1997;Bouman et al, 1999;Roa-Fuentes et al, 2013), the suppression of the dominance of the pioneer species in early succession and the acceleration of old-field succession at least temporarily (Li et al, 2007). Legume indicated greater soil organic carbon, microbial biomass and coefficient, a higher carbon use efficiency of microorganisms, higher enzyme activities and soil microbial activity (Fterich et al, 2014).…”

Legume species were more and more commonly introduced to degraded grassland for human‐aided restoration. This study aimed to test whether the natural spread of legume contributes to reversal of grassland degradation through making an extensive grassland vegetation and soil survey in Inner Mongolia of China. The results showed that legume biomass increased along a gradient of soil coarsening that was also a gradient of grassland degradation. The total biomass rather than legume biomass was limited by mean annual precipitation at plot level. The presence of legumes increased species richness in degraded steppe vegetation. Constancy of intermediate and climax species of vegetation succession at sites with legumes was higher than that at sites without legumes, implying that legumes might contribute positively to the reversal of grassland degradation. Our study suggests that naturally distributed legumes could benefit the reversal of grassland degradation through promoting plant community succession rather than total plant biomass. Planting legumes would be an effective measure to accelerate the recovery process of degraded grassland with coarsened soil in regions similar to our study region.

“…Collectively, these results demonstrate that dune revegetation with shrubs can alleviate wind erosion and shelter the surface soil layers from erosion by absorbing the wind's momentum (Buckley, ; F. R. Li et al, ; F. R. Li et al, ; Raupach, Gillette, & Leys, ) and reducing the velocity of the wind near the surface (Geddes & Dunkerley, ; Kidron, Vonshak, & Abeliovich, ). Meanwhile, a large amount of transported fine materials are trapped by planted vegetation (J. H. Li, Fang, Jia, & Wang, ), thus increasing fine particles at the soil surface of 0–10 cm. Likewise, the content of silt and clay at 10–20 cm depth also increased with time, though less than that at the soil surface (Figure ).…”

This study used a 40‐year chronosequence of Haloxylon ammodendron plantations to evaluate its impacts on soil and vegetation conditions in a desert–oasis ecotone with extremely low annual precipitation (≈100 mm). We found that the fraction of silt and clay contents significantly increased from 6.4% and 5.1% in Year 0 to 22–23.3% and 15.8–18% in the 40‐year‐old plantation in the soil depths of 0–10 and 10–20 cm, respectively. Soil nutrients (i.e., soil organic matter, total nitrogen, and total phosphorus) were significantly improved after H. ammodendron plantations. However, there was a significant increase in soil salinity, which may negatively affect sustainability of ecosystem restorations in future (drier and warmer) climate. Planted H. ammodendron established and thrived in the first 25 years, but the percent vegetation cover started to decrease afterwards because of reduction in deep soil moisture and less access to groundwater. By comparison, herbaceous plants gradually developed after H. ammodendron plantations and finally dominated the ecosystems with high density (300–400 herbs·m−1), cover (25–30%), and biomass (50–60 × 10−3 kg·m−2) after 30–40 years. These results suggest that although introduced shrubs can act as nurse plants to improve vegetation and soil conditions, their dominance could be a transient state. Thus, evaluation of ecosystem restoration through plantations should use long‐term data, and the stable plant restorations for years or even decades could be a transient state and does not necessarily suggest a successful revegetation effort in the long run. Further, its environmental consequences (i.e., soil salinity) of shrub plantations need to be evaluated in ecosystem restorations especially in a changing and harsh environment.
