We also applied Gini coefficient study evolutionary trend matching between consumption GDP each sector. Based on above analysis, developed a coupling model incorporating various indicators relevant three subsystems quantitatively assess coordinated development basin from 2004 2020. The main findings are as follows: (1) Basin suffers dry years, with prominent supply–demand contradiction. In severe drought years 2009 2014, reached 10.20% 10.93%, respectively. (2) From 2020, Basin’s efficiency (WUE), its five prefectures showed clear upward trend. On multi-year average, Bayingol Mongolian Autonomous Prefecture had highest WUE, while Hotan region lowest. (3) average value match for entire is 0.28. By industry, primary industry’s higher, secondary tertiary industries have lower matches. (4) different degrees trend, generally developing towards better coordination. terms averages, Prefecture, located east, has Meanwhile, Hotan, south, lags significantly behind remaining four regions.

The lower course of the Yellow River is a “hanging river” across hinterland China, and safety its flood control measures/systems closely tied to stability nation. Ensuring high-quality, sustainable development floodplain while maintaining crucial for entire Basin. Previous studies have primarily focused on overall Basin or economic–ecological coupling cities along river, often neglecting floodplain. This study optimizes socio-economic–flood-safety–ecological (SFE) system typical downstream Landong within dynamics model (SDM) can simulate dynamic behavior SFE systems by constructing mathematical models that incorporate feedback loops time delays. primary components include causal loop modules stock-flow modules. Then, coordination degree established using comprehensive subjective objective weighting method, assessing system’s under five scenarios: inertial development, economic environmental protection, safety, development. results historical validity tests indicate SDM effectively system. suggest increases most scenario, indicating should not only focus socio-economic growth, but also consider ecological concerns. In addition, regulation from socio-economic, environment indicators are necessary achieve coordinated has significant implications policy formulation management high-quality in River.
