| Summary: | Understanding the interrelationship of flood-sediment transport (FS), eco-environment (EE), and socio-economy (SE) is crucial for promoting systemic governance of the Yellow River Basin (YRB). Considering the characteristics of the YRB, we proposed a complex basin-wide analytical framework consisting of FS-EE-SE (FES) system. Firstly, we used the entropy weight method to determine the indicators weights and built the coupling coordination degree (CCD) model. Secondly, Grey relational analysis and obstacle degree (OD) model were developed to identify the major factors affecting the coordinated development of the FES system. Finally, the Convolutional Neural Network and Long Short-Term Memory (CNN-LSTM) model was selected to predict the CCD under different scenarios. The results showed that: (1) At the scale of river reaches, the CCD of the middle reaches was highest. At the provincial scale, the CCD showed a “low in the west and high in the east” pattern. (2) The results of grey relational analysis showed that runoff characteristics were the major driving factors at the two scales. With the optimization and adjustment of agricultural structure in the YRB, the results of OD model showed that the cultivated land area was the major obstacle factor at the scale of river reaches. Annual maximum sediment concentration was the major obstacle factor of the FES system at the provincial scale. (3) In 2023-2030, the coordinated development level of the FES system will continue to decline, but in the scenario of “regulating the water–sediment relationship”, the coordinated development level of the FES system will be further improved. In the future, the coordination of water–sediment relationship still be the key issue for the YRB. The government should implement the integration of regional governance and coordinate the water–sediment relationship. These results offer an important reference value for promoting the systemic governance in the YRB. |
