Research Progress on Soil Erosion and Ecological Restoration in Kuye River Basin of the Middle Yellow River
The ecological protection and high-quality development of the Yellow River Basin are key national strategies in China.Kuye River Basin is a major area for soil erosion and the primary source of coarse sediment in the upper and middle reaches of the Yellow River Basin.In recent years,with the implementation of a series of major water conservancy and ecological projects,signif-icant achievements have been made in soil erosion control and ecological restoration in this area.However,this area,situated in the transition zone between the Pisha sandstone hilly and gully area and the Mu Us sandy land,still faces severe water and wind erosion.The ecological environment remains fragile,and governance quality needs urgent improvement.Numerous scholars have made significant contributions to understanding the soil erosion mechanism in this area,but the hydrologi-cal underlying surface in this area is complex and changeable,and the erosion types are diverse and complex.Previous studies still adhere to the theories and methods of the Loess Plateau,significantly limiting the development of soil erosion mechanism research in Pisha sandstone area.Based on the previous research results and the author's scientific research experience,this paper summarizes the achievements of Kuye River Basin,sorts out the soil erosion mechanism and ecological restoration technology in this area,analyzes the problems existing in the soil and water loss control in this area,and finds that the research on the composite erosion mechanism of Kuye River Basin is relatively weak.Accurate determination of the regional water carrying capacity threshold is necessary,and the social and economic benefits of soil and water conservation measures in this area need improvement.The supervision of soil and water conservation needs to be transformed into wisdom,which provides direction for future research on soil erosion mechanism and ecological restoration in the Kuye River Basin.
