The Study of Collapsible for Intact Loess and Remolded Loess [PDF]

Proceedings of the 2015 International Conference on Mechatronics, Electronic, Industrial and Control Engineering, 2015
At present, there are not enough research for the intact loess and remolded loess collapsible; There are tests for the some region loess, to study the law of collapsible.The results showed that: The curve of intact loess and remolded loess collapsible deformation is defined by two turning points and three segments.The collapsible coefficient of intact ...

Moss Biocrusts Regulate Heavy Metal Speciation and Mobility in Coal Mine Soils

Land Degradation &Development, EarlyView.
ABSTRACT On a global scale, coal mining activities often lead to heavy metal(loid) contamination in soils of mine dump sites, posing serious ecological risks. As ecosystem “engineers,” biological soil crusts (biocrusts)—especially moss crust—have shown great potential in remediating heavy metal‐polluted soils, but their roles remain underexplored.

Long‐Term Combined Application of Biochar and Chemical Fertilizers Enhances Potassium Supply Capacity in Continuous Cropping Soils

Land Degradation &Development, EarlyView.
ABSTRACT Sustaining soil potassium (K) supply in intensive continuous cropping systems is increasingly challenging because long‐term crop removal often exceeds the natural replenishment capacity of soil K‐bearing minerals, leading to progressive depletion of plant‐available K pools.

Hazard assessment of seismic-collapsed loess landslides on the Loess Plateau as exemplified by the M6.2 earthquake in Jishishan County, China

Frontiers in Earth Science
The Loess Plateau is marked by intense neotectonic activity and frequent earthquakes. Its unique physico-mechanical properties, combined with the granular overhead pore structure of loess, render it prone to seismic landslides triggered by strong ...

Integrating Machine Learning and StoDyM for Check Dam Site Selection on the Loess Plateau, China

Land Degradation &Development, EarlyView.
ABSTRACT Severe soil erosion in the Loess Plateau has led to significant land degradation, threatening agricultural productivity and ecosystem stability. Check dams, as a critical soil–water conservation measure, have proven effective in mitigating sediment loss and reclaiming farmland.

Divergent Blue Carbon Trajectories in the Yellow River Delta Post‐1976 Diversion: Hydrological Stability and Human Disturbance Contrasts Revealed by Multi‐Source Remote Sensing (1984–2023)

Land Degradation &Development, EarlyView.
ABSTRACT Coastal wetlands are critical blue carbon sinks, yet their spatiotemporal dynamics under environmental change remain insufficiently quantified. Taking the Yellow River Delta (YRD) as a natural laboratory, this study synthesizes multi‐source remote sensing data, including optical and radar imagery spanning from 1984 to 2023, to explore the ...

Establishing Monthly Benchmarks for Erosion Control and Vegetation Restoration Targets Across the Loess Plateau

Land Degradation &Development, EarlyView.
ABSTRACT Establishing scientifically grounded soil erosion control targets and feasible vegetation restoration strategies is crucial for high quality development of the Chinese Loess Plateau which is severely affected by soil erosion. Currently, the commonly used tolerable soil loss (TSL) is inadequate for addressing the spatial heterogeneity in ...

Characteristics and Influencing Factors of Soil Shear Strength in Gully Erosion at Different Developmental Segments of Subalpine Meadows

Land Degradation &Development, EarlyView.
ABSTRACT Subalpine meadows play important roles in biodiversity conservation and soil carbon sequestration, but gully erosion poses a serious threat to their ecological stability. Soil shear strength (τ) is a key mechanical parameter for evaluating gully stability and soil resistance to failure. However, the spatial variation in soil shear strength and
