Higher requirements for the protection and management of the Yellow River were put forward, and also new opportunities for the development were provided in the Yellow river Basin following the established strategy of the ecological protection and high-quality development of Yellow river Basin. In this paper, the present situation of water security was analyzed, the connotation of high-quality development was discussed and the main problems existing in water security and high-quality development was summmarized in the Yellow River Basin; then, the ideas for the water security and high-quality development of the Yellow River were discussed and the corresponding suggestions were proposed. The main problems of water security and high-quality development in the Yellow River are shortage of water resources, frequent floods and uncoordinated relationship between water and sediment, serious soil erosion and fragile water ecological environment, deficient water resources operation and regional water supply project and weak cooperative management ability of the river basin. Focusing on the issues discussed above, the ideas were put forward from six aspects including disaster prevention and mitigation, water network optimization, ecological protection and restoration, efficient use of water resources, basin management capacity and scientific support. Meanwhile, suggestions were proposed based on strategic planning promotion, development plans formulation, technological innovation and support enhance, institutional innovation exploration, ecological conservation and restoration plan boost and the rule of law promotion, which provided references for water security and high-quality development of the Yellow River.

There are some divergences of understanding in the development of the Heishanxia reach of the Yellow River. After the ecological protection and high-quality development of the Yellow River basin raising to a major national strategy, it is necessary to think and examine the development of the section from a strategic perspective. This paper analyzed the new situation and problems facing the development of the Heishanxia reach of the Yellow River and studied the effect of the development of the section in the coordination of the Yellow River’s water and sediment, ice flood control, water supply and power generation. The effect of the regional economic and social development was considered. The development of the reach is in line with the major national strategic requirements for ecological protection and high-quality development in the Yellow River basin and has an important supporting role in promoting the implementation of major national strategies. It is recommended to choose a suitable development plan, promote the project to be established as soon as possible and build a multi-energy complementary base relying on the development of the Heishanxia reach.
