Preliminary study on harnessing strategies for Yellow River in the new period

"Less water, more sand, and lack of balance between water and sediment" is the historical contradiction of harnessing the Yellow River. In the new period, the contradiction of harnessing the Yellow River has taken place significant changes. "More sand" has been sharply controlled, and"lack of balance between water and sediment" has been alleviated to a certain extent, while "Less water" has evolved into the main aspect of the contradiction of harnessing the Yellow River. Facing the ecological protection and high-quality development of the Yellow River basin in the new period, the idea to deal with the contradiction of harnessing the Yellow River is to "increase water, decrease sand, improve water and sand regulation ability", for the promotion of water and sand coordination. The implementation of western water transfer is a strategic measure to solve the contradiction of harnessing the Yellow River. It can not only support the water demand for high-quality development in river basin, guarantee the long-term peace and stability of the Yellow River, but also effectively improve the ecological environment quality of the Huang-Huai-Hai Plain. Based on the principal contradiction and the law of development and change of harnessing the Yellow River, five strategies of harnessing the Yellow River in the new period are put forward, namely, adhere high-quality development with ecological priority; adhere to the systematic management and protection strategy based on water; adhere to the comprehensive prevention strategy based on extreme disaster risk; adhere to the coordinated control strategy based on natural and social water circulation in the river basin, and adhere to the five balanced control strategies based on the overall planning of river basin and region. © 2019, China Water Power Press.
