Abstract

Soil erosion is a process triggered by natural forces such as water and wind that strips away the soil layer from the Earth's surface and transports it elsewhere, posing a significant threat to agricultural production and human habitats. To quantify the temporal‐spatial response of surface soil erosion to land use/land cover (LULC) and slope changes in Qianhe Graben during 2003–2018, remote sensing and DEM data were integrated to estimate by using Revised Universal Soil Loss Equation (RUSLE) model. Our results showed that the surface soil erosion in the study area was at a slight or low level and decreased with a rate of 0.74 t ha⁻¹ year⁻¹. The mean erosion rates of different LULC in Qianhe Graben followed by sloping cropland > barelands and residential areas > flat cropland > grasslands > woodland, which is related to the LULC transformation process. Finally, the total soil loss amounts are mainly distributed at the slope zones of 8°–15° and 15°–25°, particularly for cropland in hilly and gully areas. Overall, these results not only give evidence for the effectiveness of the “Grain‐to‐Green” Project but also give significant assistance for the implementation of soil and water conservation measures.

期刊介绍： Environmental Earth Sciences is an international multidisciplinary journal concerned with all aspects of interaction between humans, natural resources, ecosystems, special climates or unique geographic zones, and the earth: Water and soil contamination caused by waste management and disposal practices Environmental problems associated with transportation by land, air, or water Geological processes that may impact biosystems or humans Man-made or naturally occurring geological or hydrological hazards Environmental problems associated with the recovery of materials from the earth Environmental problems caused by extraction of minerals, coal, and ores, as well as oil and gas, water and alternative energy sources Environmental impacts of exploration and recultivation – Environmental impacts of hazardous materials Management of environmental data and information in data banks and information systems Dissemination of knowledge on techniques, methods, approaches and experiences to improve and remediate the environment In pursuit of these topics, the geoscientific disciplines are invited to contribute their knowledge and experience. Major disciplines include: hydrogeology, hydrochemistry, geochemistry, geophysics, engineering geology, remediation science, natural resources management, environmental climatology and biota, environmental geography, soil science and geomicrobiology.
