【 摘 要 】

Constrained by the special physiographic conditions and the progress of safety construction, the economic development in the floodplain area is slow and people still live in poverty. This study aimed to propose a reconstruction and ecological management concept, "flood control with graded, standard sediment deposition in the partitioned zone, regionalized reconstruction, and the development of the floodplain" with the guidance of the national development strategy and the current water management policy. This was after considering the natural characteristics and physics of the flow and transport of sediments in the Lower Yellow River floodplain. The reconstruction and ecological management of the Lower Yellow River floodplain is an effective combination of river management and economy development, which is in accordance with the national requirement for ecological civilization construction. Moreover, this was vital in taking targeted measures to help people out of poverty and promoting the development of the Central Plains Economic Zone. It is advised to conduct studies on schemes for the reconstruction and ecological management of the Lower Yellow River floodplain. Pilot projects should be launched in selected reaches to conduct reconstruction experiments, and then the experience can be popularized along the entire lower river.
