In order to provide scientific and technological support for the implementation of major national strategies for ecological protection and high-quality development and rural revitalization in the Yellow River Basin, this paper systematically summarized the research results, key technologies and typical models of the coordinated development of ecological governance and ecological economy in the Yellow River Basin over the years, analyzed the current existing and outstanding issues, and put forward corresponding countermeasures and suggestions. Over the years, various regions in the Yellow River Basin have explored a variety of coordinated development models of ecological governance and ecological economy for serious soil erosion. It includes the comprehensive ecological and economic management model with high adaptability of soil and water conservation-geomorphology-ecological economy, the ecological agriculture economic model of soil and water conservation, the integrated development model of soil and water conservation and ecological economy in wind-sand area, the coordinated development model of ecological management and derivative industries in Pisha sandstone area, the virtuous cycle model of rural energy ecology in semi-arid areas, and the governance model of ecological and economic belt of soil and water conservation in the Loess Plateau. At present, the existing outstanding issues include the concept of coordinated development of ecological governance and ecological economy is weak, the synergy between the two is not high, the space for coupling and coordination is unbalanced, and the development model has a single structure and low scale efficiency. The suggestions: To innovate the theory and key technologies of coordinated development of ecological governance and ecological economy; To establish a diversified investment mechanism, create a new model of coordinated development of ecological governance and economy and its production and industrial system with the goal of high-quality development, and explore the promotion mechanism and model of “full trust and full chain”; To build an appropriate technical system, industrial system, management system and talent support system; To establish a pilot demonstration county for the coordinated development of ecological governance and ecological economy, lead and optimize the coordinated development of regional modern ecological governance and economy.

In order to scientifically predict the future sediment load of the Yellow River, support the Yellow River harnessing and development and major project construction and based on the analysis of the characteristics and causes of the variation of water and sediment in the near future, this paper used the hydrological method and the genetic analysis method to predict the future sediment amount of the Yellow River, at the same time, the large flow duration and the water volume which were beneficial to sediment transport were greatly reduced, the dynamics of flow and sediment transport were greatly weakened, and the relationship between water and sediment was still not coordinated. Without considering the sediment retention of the Xiaolangdi Reservoir, the downstream channel would still be silted up. It is considered that the main influencing factors of the recent sediment reduction are the massive construction of water conservancy and soil and water conservation measures and the reduction of rainfall intensity, which account for 80% and 20% respectively, taking into account the existing research results and the uncertainty of the forecast, it is suggested that the average annual sediment hydraulic engineering of the Yellow River in the future should be about 800 million tons.
