Studies on the Key Problems of the Construction of Yellow River Water and Sediment Regulation and Control System

摘要

In this paper,the situation and existing problems of the Yellow River water and sediment regulation and control system were analyzed based on the root problem of Yellow River,which is summarize as insufficient water,excessive sediment and imbalance of the two.The overall arrangement of Yellow River Water and Sediment Regulation and Control System was presented here according to the demand of the storm flood and ice flood control,sediment deposition reduction and water resource configuration of the Yellow River.The regulated sediment-laden flood characters and operated ways of Yellow River water and sediment regulation and control according to the demand to maintain the capacity of release the flood and sediment,to assure the safety of the storm flood and ice flood control and to realize the effective management and configuration of Yellow River water resource.The built order of key projects was determined by analsing the development tasks,the status and role in Yellow River Water and Sediment Regulation and Control System and the urgent requirements of the regulation and development of Yellow River.Besides,the role of Guxian Reservoir in the Yellow River was analyzed,the result shows that it occupies a strategically important position in the regulation and development of Yellow River and plays an important role in the flood control,so it is vital necessary and urgency to accelerate the construction of Guxian Reservoir.
