Abstract： From the perspective of systematic thinking, this study applied the theories of information entropy and dissipative structure to comprehensively evaluate and analyze the evolution of the complex system of the Yellow River Basin over the past 40 years. With the concept of “Basin Development Index (BDI shortly)”, a preliminary scientific comprehensive evaluation method system of basin development quality is established. Results of the model calculation show that the ratio of per capita GDP in the basin to the national average and the total sedimentation in the lower Yellow River have occupied the largest weight for many years, and have had a relatively greater impact on the development of the basin in different historical periods. During the entire 40 years, the value of BDI has varied from 50.5 points in 1996 to 66.6 points in 2019, and has generally experienced a decreasing and an increasing stage. The evolution of BDI of Yellow River basin is consistent with the overall law of the basin development and has a great correlation with some major events happened in the basin. In addition, this research method can be extended to other fields such as regional governance. Compared with the current evaluation models mainly based on economic indicators, this novel methodology is more systematic and scientific, and will better serve the decision-making with more scientific thoughts.

Abstract： This paper proposes a unitary clean energy construction model based on the complementary multi-energy of wind, light, hydropower and pumped energy storage, combined with the Heishanxia, Qikou and Guxian water conservancy projects planned by the Yellow River water and sediment regulation system, relying on the Yellow River the rich water, wind, light, land, and terrain resources in the Ω Region are controlled by the power supply to achieve stable output, and the idea of building three clean energy bases with complementary wind, light, water, and pump energy storage is proposed to replace fossil energy, realize water saving and emission reduction, and help the ecological protection and high-quality development of the Yellow River Basin.
