Coupled coordination of water resources–economy–ecosystem complex in the Henan section of the Yellow River basin

Abstract

This study investigates the coordination of factors in the three coupled systems of water resources, economy and ecosystem. The study data were economic, social, environmental and water resource indicators of the Henan section of the Yellow River basin from 2000 to 2019. Data were analyzed using a model of coupling coordination, grey relational analysis and a combined sparrow search algorithm-back propagation (SSA-BP) prediction model. Evaluation, analysis and prediction of the water resources–economy–ecosystem complex were undertaken. The results show that: (1) The degree of coupling coordination of the water resources–economy–ecosystem complex in the Henan section of the Yellow River basin showed an increasing trend that reached 0.8105 in 2019, which indicates good coordination; (2) The water resources subsystem had the greatest influence on the overall degree of coupling coordination, followed by the economic and natural environment subsystems; and (3) The SSA-BP model predicted that the degree of coupling coordination would remain good for the next six years and reach 0.8333 in 2025. To ensure the sustainability of expected rapid economic development, Henan Province must increase the utilization efficiency of water resources, strengthen environmental protection, and coordinate development in the region.

Temporal and Spatial Changes of Hydrographic Connectivity with the Development of Agriculture, Industry, and Urban Areas: A Case Study of the Yellow River Basin in Henan Province during the Last Two Decades

“…In 2022, Wang studied the coupling and coordination relationships among the water resources, economic, and ecosystem systems in the Henan section of the Yellow River Basin. The results indicated a gradual increase in the overall coordination of the system during the period from 2000 to 2019, with the water resources system identified as the most influential subsystem within the comprehensive system [39]. This finding further demonstrates that changes in the structure and hydrological morphology of the river network not only affect its structural connectivity but also have implications for functional connectivity.…”

Coordination analysis of flood-sediment transportation, eco-environment, and socio-economy coupling in the governance of the Yellow River Basin system

“…The basin is both a whole and has significant spatial heterogeneity, with complex and diverse forms of problems caused by the interaction between the river itself, the ecological environment, and socio-economic factors. At present, research on the elements of the Yellow River Basin system mainly includes water, energy and food 63 , low-carbon development and eco-environment 65 , sustainable development and environmental protection 66 , water utilization, industrial development and ecological welfare 67 , urbanization and water resource 78 , urbanization and ecosystem service value 79 , ecology and economy 80 , resources, economy and ecosystem 81 , human settlement environment and tourism industry 82 , public health, ecological environment and economic development 83 . agricultural carbon emissions efficiency and economic growth 84 , tourism, ecological-environment and public service 85 .…”

Spatio-Temporal Dynamics of Economic Density and Vegetation Cover in the Yellow River Basin: Unraveling Interconnections

“…In the Henan section, areas with high and medium-high vegetation cover are predominantly concentrated in the western Funiu Mountain, northern Taihang Mountain, and eastern plain areas. Conversely, regions with medium, medium-low, and low vegetation cover are mainly found in the central Luoyang to Zhengzhou section, with bare land primarily distributed along the water system and both sides of the YRB [13]. The Inner Mongolia section, situated in an arid-semiarid region, relies on groundwater for vegetation, and increased rainfall stands as the primary driver for heightened vegetation cover [14].…”
