Summary: This study evaluated the impacts of slope gradients on soil erodibility in semiarid regions and found that soil cohesion, penetration resistance, erodibility K factor, and integrated soil erodibility index increased with the slope gradient, while saturated conductivity, mean number of water-drop impacts, and mean weight diameter showed the opposite trend. Significant differences were found between different slope classes, and suggestions for soil erosion control on medium and steep slopes were provided.

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: Vegetation restoration is a crucial strategy for addressing global climate change challenges. Slope measures, such as infiltration holes and mulching, can effectively improve soil environments. However, the additional effect of mulching in enhancing the improved effects of infiltration holes on soil environments is limited.

Summary: This study investigated the changes in vegetation and soil properties over time in natural and artificial vegetation types. It found that natural vegetation improved both plant community and soil properties, while artificial vegetation only improved soil nutrients but caused soil desiccation which is difficult to recover.

Summary: Studies on vertical soil nutrient distribution beneath different types of artificially restored vegetation in a transition zone from desert to loess revealed distinct hierarchies in soil nutrient content, with Medicago saliva vegetation being the most suitable for restoration. Soil nutrient content was positively correlated with soil water content, plant coverage, and clay, silt, and litter nutrient content, but negatively correlated with soil bulk density, sand content, and litter C/N ratio.

Summary: Water deficits in crop production, caused by depleting water supplies and high water-demanding crops, have become a major concern in semiarid regions of China. A six-year field experiment was conducted to evaluate soil water recovery and fertility after converting lucerne to different crops on the western Loess Plateau. The findings show that all rotation types gradually increased soil water content, but decreased organic carbon and total nitrogen in the soil.

Summary: Ecological restoration projects have increased vegetation cover and reduced soil erosion globally. However, understanding the complex soil erosion mechanisms of limestone and dolomite in the southwest karst region and identifying key factors affecting erosion is challenging. This study found that vegetation restoration reduces soil erosion by influencing soil particle composition, with clay content being the key factor.

Summary: Mixed-species plantations are widely promoted for ecosystem restoration and soil quality improvement. However, the effects of species mixtures on soil water conditions are still debated. This study monitored and quantified vegetation characteristics, soil properties, and soil water storage (SWS) in pure and mixed plantations. The results showed that SWS in pure plantations of Robinia pseudoacacia and Armeniaca sibirica were higher than their mixed plantations, while SWS in the pure plantation of Hippophae rhamnoides was lower than its mixed plantation. Soil properties contributed more to SWS than vegetation characteristics and slope topography, and plant density and height were important factors for SWS. The study provides scientific support for improving revegetation techniques in the region.

Summary: Effectively regulating slope runoff and infiltrating maximum rainwater are essential to reduce soil and water loss, and promote vegetation restoration in the Pisha Sandstone areas of China, which are semiarid areas with shallow buried bedrock. The study investigated the responses of soil water to rainfall in the 0-1.6 m soil layer under four rainwater regulation treatments, and concluded that the PGH treatment was effective in increasing soil water storage and reducing soil erosion in areas with shallow buried bedrock.

Summary: The study suggests that chemical weathering and CO2 consumption in the glaciated area of the Tibetan Plateau exhibit regional differences, with silicate weathering being influenced by temperature and carbonate weathering dominating riverine solute generation. Moreover, the oxidation of pyrite leads to carbonate weathering in the upstream and midstream regions not consuming atmospheric CO2.

Summary: This study investigated the mean annual runoff and sediment yield in eight headwater catchments on the Tibetan Plateau and examined their relationships with annual precipitation, air temperature, and glacier area ratio. The results showed that runoff was positively correlated with precipitation and temperature, while sediment yield exhibited an inverted parabolic relationship with precipitation and a positive correlation with glacier area ratio. These findings are important for understanding environmental changes and erosion rates on the Tibetan Plateau.

Summary: This study assessed the geochemical characteristics and associated health risks of arsenic in natural waters in the Indus River Basin (IRB), Pakistan. A total of 203 samples of different water types were collected and analyzed. The results showed that arsenic concentrations in the waters ranged from 1.1-26.45, 1.05-44.44, and 0.67-41.09 μg/L for surface water, shallow groundwater, and deep groundwater, respectively. The desorption of arsenic in oxidizing environments with elevated pH and Eh was identified as the controlling mechanism.

Summary: The alpine lakes on the Tibetan Plateau have undergone significant changes due to climate change in recent decades. However, the changing patterns of inflow sources, including rainfall and meltwater from snow and glaciers, and their responses to climate change remain uncertain due to the complex topography and limited data in the alpine area. In this study, a distributed hydrological model was used to simulate the runoff variations of a glaciated basin in Yamzho Yumco Lake. By combining precipitation data from high-resolution reanalysis and field observations, the uncertainty of inflow components in the model was reduced. The results showed that rainfall runoff, glacier melt runoff, snowmelt runoff, and baseflow contributed to the total runoff, with varying proportions and seasonal variations.

Summary: In this study, the impacts of climate change on water resources and the water cycle in the Yarlung Tsangpo River basin were assessed using the SWAT model. The results showed an increase in total runoff and its components (surface runoff, interflow, and groundwater) from 1983 to 2017, attributed to increased precipitation. Future predictions indicate a warming and wetting trend in the study area from 2020 to 2100, with an increase in total runoff, mainly driven by surface runoff.
