“…Previous studies confirmed that the ability of different vegetation restoration types to improve soil quality are different (Yu et al, 2018;Dang et al, 2020;Liu et al, 2020). In this study, the effect on soil quality (0-30 cm) of natural shrubland was significantly higher than that of Eucalyptus robusta, Prunus salicina and Juglans regia-crop (Fig.…”

Soil quality assessment is important for karst ecosystems where soil erosion is significant. A large amount of vegetation restoration has been implemented since the early 21st century in degraded karst areas across southwestern China. However, the impacts on soil quality of different restoration types rarely have been compared systematically. In the current study, we investigated the soil quality after a number of vegetation restoration projects as well as their adjacent cropland by analyzing soil samples. Six vegetation restoration types were evaluated, including one natural restoration (natural shrubland, protected for 13 years), three economic forests (4 years Eucalyptus robusta, 4 years Prunus salicina and 6 years Zenia insignis) and two mixed forests (1 year Juglans regia–crop and 13 years Toona sinensis-Pennisetum purpureum ). We evaluated the benefits of different restoration types more accurately by setting each adjacent cropland as the control and setting the variation between the corresponding restored and control site as the evaluation object so that the background differences of six sites could be eliminated. The results indicated that natural shrubland, Toona sinensis-Pennisetum purpureum and Zenia insignis were effective in improving soil quality index (SQI) in degraded karst cropland largely due to their higher SOC and TN content. The variation of SQI (VSQI) of natural shrubland was significantly higher than that in Eucalyptus robusta, Prunus salicina and Juglans regia-crop in total soil layer (0–30 cm) (P < 0.05), indicating natural shrubland had better capacity to improve soil quality. The boosting regression tree model revealed that vegetation restoration type explained 73.49% and restoration time explained 10.30% of the variation in VSQI, which confirmed that vegetation restoration type and restoration time are critical for achieving soil reserves. Therefore, it is vital to select appropriate vegetation type in restoration projects and recovery for a long time in order to achieve better soil quality. The current study provides a theoretical basis on which to assess the effects of different vegetation restoration types on the heterogeneous degraded karst areas.

“…Changes in land use and cover with respect to preexisting natural grasslands can alter plant community composition and soil characteristics (Dang et al, 2019; Huang et al, 2018; Merbold et al, 2014). These alterations can, in turn, affect soil microbial communities (Du et al, 2019; Qi et al, 2017; Yokobe et al, 2020) and their attendant biogeochemical cycles (Kaushal et al, 2014; Pataki et al, 2011; Xiao et al, 2018).…”

Efforts to enhance food, fibre, and forage yields and achieve global food security have included the conversion of natural grasslands to cultivated grasslands. The quantitative effects of a global shift in grassland management on soil properties and microbial communities critical to ecosystem function have remained largely unexplored, particularly on China's Qinghai–Tibetan Plateau. Accordingly, the distinct and contrasting effects of annual Avena grasslands (AAG) versus perennial Elymus nutans Griseb. cultivated grasslands (PEG) on the region's soil properties and microbiome were investigated in an effort to examine their contribution to maintaining soil carbon and nutrients. Across three sites per grassland type, soil moisture content (45.55%), soil organic carbon (48.97 g kg−1), soil total nitrogen (5.13 g kg−1), and soil ammonium nitrogen (298.32 mg kg−1) were 19%–32% greater at PEG sites than AAG sites, whereas soil pH (7.81), soil total phosphorus (0.44 g kg−1), and soil available phosphorus (0.81 mg kg−1) were 2%–31% lower. The AAG and PEG site soils had different bacterial and fungal β‐diversities but similar α‐diversities. The relative combined abundance of Gemmatimonadetes and Chytridiomycota, and that of Rozellomycota individually, were, respectively, higher and lower in AAG versus PEG site soils. This suggests that, on the Qinghai–Tibetan Plateau, contrasting grassland cultivation practices affect soil properties and microbes differently. Given the strong interaction between a soil and its microbiome, changes in a soil's microbial community structure can be expected to substantially alter soil function. This will have important ecological service implications, particularly in terms of carbon storage and water conservation in this ecologically fragile region.

Mining areas are currently a typical ecosystem that is severely destroyed within the world. Over the years, mining activities have caused serious soil damage. Therefore, the soil restoration of abandoned mines has become a vital sustainable development strategy. The ecological environment within the hilly area of the Loess Plateau is extremely fragile, with serious soil erosion; Robinia pseudoacacia is the most popular tree species for land reclamation in mining areas within the Loess Plateau. To review the different various effects of Robinia pseudoacacia on soil quality below different configuration modes, this paper has chosen two sample plots within the southern dump of the Pingshuo mining area for comparison. The first plot is a Robinia pseudoacacia-Ulmus pumila-Ailanthus altissima broadleaf mixed forest, and the second plot is a locust tree broadleaf pure forest. The vegetation indicators and soil physical and chemical properties of the four stages in 1993, 2010, 2015, and 2020 were investigated. Principal component analysis is employed to develop the Soil Quality Index to perceive the changes within the Soil Quality Index over time. It is calculated that the Soil Quality Index of Plot I rose from 0.501 in 1993 to 0.538 in 2020, and Plot II rose from 0.501 to 0.529. The higher the SQI, the higher the reclamation of the mining area. It is found that Robinia pseudoacacia within the Robinia pseudoacacia-Ulmus pumila-Ailanthus altissima broadleaf mixed forest has higher soil quality improvement than the pure genus Robinia pseudoacacia broadleaf forest. This article can demonstrate the changes in the quality of reclaimed soil in the mining area, and can also provide a reference for the selection of reclaimed vegetation in other mining areas.
