The anti-erosion effect of an anionic polymer based on polyacetonitrile, "VPRG reagent (dry hepane)", has been studied when its solution was applied to the surface of agro-black earth, sand and clay in laboratory conditions. It has been found that the use of VPRG has a clearly positive effect only on the anti-erosion stability of agro-black earth; a weak positive effect was observed on clay, and an increase in the amount of washed-off material was noted on sand relative to the standard. It has been confirmed that an increase in the concentration of VPRG leads to an increase in the anti-erosion stability of agro-black earth, but reduces it for clay and sand relative to the standard. It has been concluded that the optimal dose of VPRG application corresponds to 106 kg/ha when dissolved in 10 m3 of water for agro-black earth and clay.

Assessing the spatio-temporal variability and driving forces of soil erosion on the Loess Plateau is critical for ecological and environmental management. In this paper, the Revised Universal Soil Loss Equation (RUSLE) model, the patch-generating land use simulation, and the Geographical Detector are used to investigate the spatio-temporal variations of the Loess Plateau’s soil erosion from 2000 to 2050. The results showed that: (1) The primary categories of soil erosion from 2000 to 2020 were moderate, mild, and slight, and the average level of soil erosion exhibited a decreasing and then an increasing tendency during the last 20 years. (2) Soil erosion was directly impacted by changes in land use, with cropland and forest being the primary land use and land cover changes in the study region. Cropland and construction land being turned into woodland between 2000 and 2020 resulted in a significant decrease in the severity of soil erosion. Projected soil erosion is expected to increase significantly between 2020 and 2050 due to arable land being converted into construction land. (3) The key variables impacting the spatial distribution of soil erosion were LUCC (Land-Use and Land-Cover Change), NDVI (Normalized Difference Vegetation Index), and slope, and the interplay of these variables may increase their ability to explain soil erosion. Grasslands with an NDVI ranging from 0.9 to 1, rain ranging from 0.805 to 0.854 m, a slope above 35°, and a terrain elevation ranging from 1595 to 2559 m were identified as having a high risk of soil erosion. Soil erosion prevention and management efforts should focus on the ecological restoration of upland areas in the future.
