Short Summary

This study constructs a multidimensional resilience evaluation index system to assess the evolution and driving mechanisms of water resource resilience in arid inland river basins. The System Coordination and Factor Interaction-based Resilience Evaluation Model (SCFI-REM) is proposed and applied to the Shiyang River Basin, revealing that total water resources have the highest explanatory power on resilience.

Objective

• Investigate the evolution and driving mechanisms of water resource system resilience in arid inland river basins under multi-factor interactions.
• Develop a comprehensive multidimensional resilience evaluation index system for assessing water resource resilience.

Study Configuration

• Spatial Scale: Basin scale (Shiyang River Basin)
• Temporal Scale: 2013-2023

Methodology and Data

• Models used:
  • Fuzzy set pair analysis
  • Gravity migration model
  • Geodetector
  • Coupling coordination degree modeling
• Data sources:
  • Shiyang River Water Resources Bulletin
  • China Meteorological Data Service Center
  • Gansu Statistical Yearbook
  • MODIS and China Land Cover Dataset (CLCD)

Main Results

• The resilience of the Shiyang River Basin remains at a low-to-medium level, characterized by weak coordination and high sensitivity to short-term hydrological fluctuations.
• Total water resources show the highest explanatory power on resilience.
• Dual-factor enhancement interactions are observed between external water transfers, reservoir water supply, industrial structure, and water use efficiency.

Contributions

• This study elucidates the formation mechanism of basin resilience under multi-factor synergies, providing a scientific basis for water resource regulation and sustainable management in arid inland river basins.
• The proposed SCFI-REM model can be applied to other similar regions to assess their resilience and inform adaptive management strategies.

Funding

• This research was supported by the National Natural Science Foundation of China (Grant No. 51879231)
