摘要：

The middle reaches of Yellow River basin, with a fragile ecological environment, are vulnerable to serious flood and drought disasters. In recent years, the controls on soil and water loss in the middle reaches of the Yellow River have been steadily improving under the influence of human activities such as large-scale terrace construction and vegetation restoration projects. These soil and water conservation measures play an important role in flood control, drought relief and disaster reduction. However, at the same time, vegetation construction in the middle reaches of the Yellow River has led to the intensification of dry soil layers, a decrease in runoff and sediment yields, and an increased hydrological drought risk. Urban expansion has also led to drastic change in this disaster-prone environment, including an increased rainstorm and flood peaks in urbanized areas, and increased flood and drought risks. In the middle reaches of the Yellow River basin, the hydrology, sediment and vegetation evolution is highly inter-connected and co-developed. With disturbance from human activities, a new hydrology-sediment-vegetation balance will form. At present, however, the co-evolution processes and mechanisms of the hydrology- sediment- vegetation balance in the basin under a changing environment is not clearly understood. The impact of large-scale distributed human activities such as terrace construction, vegetation restoration projects and urban expansion, on flood and drought disaster risks needs to be scientifically assessed. An intelligent eco-hydrological model of the Yellow River middle reaches under a changing environment should be developed to predict the long-term subsequent impact of large-scale human activities on flood and drought disaster risks. These improvements can provide scientific and technological support for the coordinated development of ecological construction and water conservancy projects in the middle reaches of the Yellow River, serving the effective prevention and mitigation of flood and drought disaster risks. © 2023 Science Press.
