In order to improve comprehensively water security capability, conside ring the existing problems of flood risk threat, the stortage of water resources, fragile ecological environment and insufficient capacity for water management that the Yellow River Basin is facing with, the water security layout with coordinated protection of five zones including the source area, the upper, middle and lower areas of the Yellow River, the Yellow River estuary and delta areas was proposed based on the idea of "Focus on Protection and Key on Management". Then, the water security measures were put forward from the five aspects of promoting the economical and intensive use of water resources to improve the support ability of water resources, perfecting the flood control and disaster reduction system to ensure the peace and stability of the Yellow Rive r, strengthening the protection of water ecological environment to safeguard the healthy life of the Yellow River, systematically implementing the integrated prevention and control of soil erosion to improve the ecological environment in the Loess Plateau and promoting the river basin management ability to support the ecological protection and high-quality development of the Yellow River Basin. Also, this paper could provide an important basis for the water security work of the ecological protection and high-quality development in the Yellow River Basin. [ABSTRACT FROM AUTHOR]

Ecological protection and high quality development of the Yellow River basin have become a major national strategy，but there are still some outstanding difficulties and issues in the current stage which need to be considered and gradually promoted from a strategic perspec¬tive. This paper systematically analyzed the outstanding difficulties and issues in the current development and utilization of water resources， sediment deposition control，flood control and disaster reduction，ecological environment protection and economic and social development in the Yellow River basin. Combining with the major national strategic requirements of ecological protection and high quality development in the Yellow River basin，according to the general idea of “combining points，lines and areas” and “five water resources with one treatment”，it put forward the key points to supplement the weak links of flood control and water & sand regulation，strengthen the protection of main and branch water environment and water ecosystem，implement comprehensive management of mountains，rivers，forests，fields，lakes and gras¬ses in the basin，for^n the overall layout and strategic pattern of protecting water resources，restoring water ecology，improving water environ¬ment， controlling water disasters，strengthening water supervision，and formulate the system and mechanism framework of basin coordination management，for maintaining the ecological health of the Yellow River and supporting the high quality development of the Yellow River basin.
