Summary: This research conducted a long-term analysis of surface runoff and soil loss on Pisha sandstone hillslopes from the Loess Plateau, China under different land use and precipitation regimes. The results showed that precipitation regimes and land use types had significant impacts on surface runoff and soil loss, with heavy storms and bare land leading to the highest levels. Therefore, the selection of land use and vegetation should be considered carefully depending on precipitation regimes in order to control soil erosion effectively.

Summary: This study analyzed the impacts of rainfall characteristics on runoff and sediment in a nested watershed with six sub-watersheds of different land uses in the Loess Plateau, China. The results showed that rainfall patterns, land use types, and hydrological years significantly affected the runoff coefficient and sediment yield. Therefore, natural restoration measures are recommended for coordinating the relationship between surface runoff and sediment yield.

Summary: Land surface roughness (LSR) is greatly influenced by vegetation restoration, which alters near-soil surface characteristics, soil erosion intensity, and spatial heterogeneity. Different plant communities have significant effects on LSR variations on steep slopes, with vegetation types and characteristics playing a crucial role in influencing LSR.

Summary: The burrowing activities of earthworms in sloping lands play a significant role in reducing nutrient loss and promoting soil stability. In this study, the presence of earthworms on artificial grass slopes led to decreases in nutrient loss in runoff and sediment, while increasing soil stability and conductivity. This highlights the importance of soil fauna in erosion and nutrient loss regulation in the Loess Plateau.

Summary: This study conducted experiments on the Chinese Loess Plateau and found that erosion-induced network of rills and gullies increased flow connectivity, resulting in uniform runoff from the upper hillslope to the headwater outlet. The results suggest that scale-independent runoff is typical of highly degraded slope systems.

Summary: Seasonal variations in soil erodibility indices were detected in different land use types on the Loess Plateau, with soil cohesion, saturated conductivity, drop impact, soil aggregate size, penetration resistance, and erodibility index generally increasing, while erodibility K factor decreasing. These changes were attributed to variations in biological soil crust thickness, plant litter density, root mass density, soil organic matter content, and soil bulk density over the course of one growing season.

Summary: Land use patterns have a significant impact on soil water content, with vegetation characteristics and soil texture mainly affecting shallow soil water content, while topographic factors play a decisive role in deep soil layers and the entire soil profile. The differences in soil water content among different land use patterns become more significant during periods of decreased precipitation.

Summary: The study compared soil C and N sequestration between artificial forests and natural grasslands converted from sloping cropland in the Central Loess Plateau, China, over 20 years post-implementation of the Grain for Green Program. The results showed that both vegetation restoration types significantly increased the soil organic carbon and nitrogen content in the top 60 cm of soil, with artificial forests having higher sequestration capacities. Soil aggregate stability and the quality of input organic matter were found to be crucial in affecting soil C and N sequestration post-restoration, with N fixing species enhancing sequestration.

Summary: This study conducted seven years of in-situ measurements and applied the WEPP model to accurately simulate and predict water erosion in the Pisha sandstone area. The results showed differences in runoff and soil loss among different land use types, with farmland having the highest values. The study highlights the importance of soil management techniques in reducing land degradation in vulnerable areas.

Summary: The study found that restored vegetation had better soil aggregate stability, soil organic carbon (SOC), and nitrogen (N) than apple orchards, and the composition of soil particles with the best aggregate stability was clay 6%, silt 8%, and sand 86%. At a 0-10 cm soil depth, soil aggregate stability had a significant positive correlation with SOC and soil total nitrogen (STN), and a negative correlation with NO3- and NH4+.

Summary: Soil erosion has significantly decreased on the Loess Plateau due to the implementation of soil and water conservation practices. This study analyzed the changes in vegetation cover and identified the distribution of terraces using remote sensing images. The results showed that vegetation restoration and terraces have played an important role in reducing soil erosion.

Summary: The study found that slope situations significantly impact soil erodibility by changing the effects of revegetation on soil properties and root traits. Different slope situations have varying effects on soil properties and root traits, which in turn affect soil erodibility.
