Short Summary

This paper critically evaluates existing methodologies for assessing the impact of large-scale vegetation restoration on the hydrological cycle in China, arguing that neglecting vegetation-induced atmospheric circulation changes biases results and proposing that initial streamflow reductions may be a transient phase that could reverse over time.

Objective

• To evaluate the methodological basis for assessing how large-scale vegetation restoration influences the hydrological cycle, particularly terrestrial water availability and streamflow, in China.
• To propose an alternative conceptual framework that explicitly couples vegetation change, atmospheric processes, and hydrological responses for a more robust assessment.

Study Configuration

• Spatial Scale: Continental scale (China).
• Temporal Scale: Long-term (ecological succession, transient vs. mature ecosystem phases).

Methodology and Data

• Models used: The paper critiques existing "moisture-recycling-based approaches" but does not use specific models itself; it advocates for new modeling frameworks.
• Data sources: Refers to "recently available data on hydrological change in China" and "recent observational evidence" consistent with the proposed interpretation, but does not specify particular datasets (e.g., satellite, observation, reanalysis).

Main Results

• Existing moisture-recycling-based approaches, which neglect vegetation-induced changes in atmospheric circulation, are predisposed to diagnose a negative effect of additional vegetation on water yield.
• Streamflow reductions associated with added vegetation in dry regions may represent a transient phase of early ecological succession, with the potential for reversal to a positive feedback between vegetation cover and water availability as ecosystems mature.
• Robust assessment of vegetation impacts on water yield necessitates frameworks that explicitly couple vegetation change, atmospheric processes, and hydrological responses.

Contributions

• Critiques the methodological limitations of current approaches (e.g., moisture-recycling-based) in assessing vegetation impacts on water yield, highlighting their inherent bias.
• Introduces a novel conceptual framework emphasizing the critical role of vegetation-induced atmospheric circulation changes and the non-linear dependence of precipitation on atmospheric moisture.
• Hypothesizes that initial streamflow reductions in dry regions due to vegetation restoration are transient, potentially reversing to a positive feedback over long-term ecological succession.
• Advocates for integrated modeling approaches that explicitly link vegetation, atmospheric, and hydrological processes for sustainable land management.
