Research Reveals Impact of Mining Restoration Strategies on Freshwater Ecosystem Services Flow

Strategic Insights -

New research conducted by China University of Mining and Technology, in collaboration with other institutions, has highlighted the profound impact of mine restoration strategies on freshwater ecosystem services flow (FSF) dynamics. The study, published in the Journal of Environmental Management, proposes a novel framework integrating FSF dynamics with regional risk assessment to address ecological restoration and resource management in mining-affected areas. The research, conducted in Liaoning Province, China, demonstrates the importance of understanding FSF processes and their interactions with mine restoration strategies for effective water resource management.

Key Takeaways:

  • The proposed framework integrates land use change scenarios based on different mine restoration strategies and evaluates their impacts in 24 simulations.
  • Quantitative analysis reveals significant spatial differences in freshwater services supply and demand, with vegetation proportion and landscape connectivity having important mediating effects in their dynamics.
  • The flow network is relatively complete, but upstream inflows are essential to alleviate resource pressure, particularly in western regions with limited or no inflows.
  • Among 24 simulated scenarios, the food supply scenario under reduced demand (Scenario 10) exhibit optimal flow patterns, while the combined development scenario under growth demand (scenario 8) highlights vulnerabilities.
  • Risk assessments reveal pronounced spatial disparities: core and improvement zones in the central Liao River and Taizi River basins exhibit low risks, while protection and restoration zones in the western Daling River basin face critical supply-demand states requiring focused interventions.
  • Vulnerable zones, characterized by limited ecological functioning and no external inflows, necessitate moderate artificial measures.
  • The proposed framework provides actionable insights for integrating FSF processes into environmental management, contributing to sustainable resource use and risk control in mining-impacted regions.

Statistics:

  • 24 simulations were conducted based on different mine restoration strategies and social demand.
  • The research evaluates the impacts of 24 simulated scenarios, including food supply and demand, combined development, and ecological protection.
  • Among the simulated scenarios, Scenario 10 (food supply under reduced demand) and Scenario 8 (combined development under growth demand) exhibit optimal and vulnerable flow patterns, respectively.
  • The surplus range of the combined development scenario (CD) is the smallest, while that of the ecological protection scenario (EP) is the largest.
  • The research highlights the importance of regional risk assessment, with core and improvement zones in the central Liao River and Taizi River basins facing low risks, while protection and restoration zones in the western Daling River basin face critical supply-demand states.
