Short Summary

This study assesses the impact of large-scale ecological restoration on terrestrial water storage using a process-based framework that integrates ecohydrological and dynamic vegetation models. The results show that ecological restoration reduces terrestrial water storage at a rate of −5.16 mm/yr.

Objective

• Investigate the impact of ecological restoration on terrestrial water storage, disentangling its effects from those of natural vegetation dynamics.

Study Configuration

• Spatial Scale: Mu Us Sandyland in China, a semi-arid region undergoing ecological restoration.
• Temporal Scale: Long-term (decadal) changes in terrestrial water storage and vegetation cover.

Methodology and Data

• Models used:
  • Tethys-Chloris (T&C): an ecohydrological model
  • Cellular Automata Tree-Grass-Shrub Simulator (CATGraSS): a dynamic vegetation model
• Data sources: Satellite observations, reanalysis datasets

Main Results

• Ecological restoration reduced terrestrial water storage at a rate of −5.16 mm/yr.
• Natural vegetation expansion and growth contributed to TWS depletion by −1.58 and −0.66 mm/yr, respectively.

Contributions

This study provides original insights into the impact of ecological restoration on terrestrial water storage, highlighting the importance of integrating natural vegetation processes in ER impact assessments.
