Multiscale Mechanisms of Hydrogel‐Induced Structural Stabilization and Erosion Resistance in Slag‐Amended Soils
Mine slag soils exhibit poor structural stability due to their lack of clay and organic matter. This study evaluated an eco‐friendly binder (SJP)—a polyvinyl alcohol/sodium alginate‐modified glutinous rice‐derived hydrogel—for improving aggregate stability in slag‐amended soils. Surface electrochemical characterization, including surface potential, specific surface area (SSA), and cation exchange capacity (CEC), combined with extended DLVO‐based …
Extracellular Enzyme Stoichiometry Reveals Microbial Nutrient Limitation Under Construction Disturbance
Construction activities are becoming increasingly frequent in alpine meadow regions, yet their effects on soil nutrient status and microbial communities remain insufficiently quantified. Taking an undisturbed fresh meadow (FM) as the reference, we examined four types of construction‐induced disturbance within the same project: stacked turf (ST), tunnel portal slope (TPS), spoil pile (SP), and camping disturbance (CD). Approximately 1 year after c…
Short‐Term Responses of Shallow‐Soil Organic Carbon Stability and Quality to Tunnel Construction on the Eastern Qinghai–Tibet Plateau
The Qinghai–Tibet Plateau (QTP), known as the “Third Pole”, plays an important role in regional and global climate regulation, but it is highly sensitive to human disturbances. Despite increasing tunnel constructions in this region, its effects on soil organic carbon (SOC) composition and stability in high‐altitude ecosystems remain unclear. In this study, soil samples were collected from tunnel‐affected (TA) and control (CK) areas across three e…
Facilitating the Restoration of Disturbed Meadow Soils Using Modified Organic Materials in the Qinghai–Tibet Plateau
As host to among the most fragile ecosystems globally, the Qinghai–Tibet Plateau is experiencing considerable ecological degradation. This study investigated the effects of modified organic materials (MOM) on restoring disturbed meadow soils in the Qinghai–Tibet Plateau. The results showed that soil water content decreased with disturbance and was increased through MOM addition by 10.86%, 5.85%, 15.20%, and 90.58% in non‐disturbed, lightly distur…
Changes in the Properties of Two Typical Plant Species and Their Rhizosphere Bacteria in Eco‐Restoration of Engineered Slopes on the Qinghai–Tibet Plateau
Slopes that are created by extensive engineering construction projects accelerate the degradation of the ecologically fragile Qinghai–Tibetan Plateau. This adverse impact can be mitigated by implementing ecologically sound restoration programs in these degraded sites. This study investigated the changes in the physiology of two typical plant species and their rhizosphere bacteria on four different engineered slopes subjected to eco‐restoration on…
Optimizing the Formulation of Engineering Slag Using Modified Organic Materials and Microbial Inoculants
As China's urbanization grows by leaps and bounds, engineering slag has turned into one of the broadest forms of solid wastes. The purpose of this research was to utilize engineering slag as a new planting substrate component to improve the soil environment in mine sites and address the growing shortage of land resources. The substrate optimal formulation was filtrated utilizing an orthogonal experiment involving four factors: slow‐release fertil…
