Short Summary

This study investigates the impact of revegetation on the shrinkage of Dalinor Lake in the Inner Mongolia Plateau, concluding that increased vegetation significantly enhanced evapotranspiration, thereby contributing to the lake's area reduction.

Objective

• To evaluate the potential influence of revegetation activities on the shrinkage of Dalinor Lake and compare it with the dynamics of Ganggeng Lake within the same basin.

Study Configuration

• Spatial Scale: Dalinor Lake basin (DLB), Inner Mongolia Plateau, China (specifically focusing on Dalinor Lake and Ganggeng Lake).
• Temporal Scale: 2000 to 2020.

Methodology and Data

• Models used: Supervised classification and visual interpretation methods.
• Data sources: Remote sensing imagery.

Main Results

• Dalinor Lake's surface area decreased by 18.68% between 2000 and 2020, primarily driven by total terrestrial evapotranspiration ($\text{ET}_t$).
• The Normalized Difference Vegetation Index (NDVI) was the dominant contributor to $\text{ET}_t$, accounting for 54.02% of its variance.
• In contrast, Ganggeng Lake expanded by 5.68%, a change strongly driven by precipitation (PPT).
• Higher levels of revegetation around Dalinor Lake led to increased NDVI and $\text{ET}_t$ and widespread declines in soil moisture, exerting significant water pressure on the lake.

Contributions

• The research highlights a critical trade-off between ecological restoration (revegetation) and water resource sustainability in semi-arid regions, demonstrating that revegetation can accelerate the shrinkage of inland lakes by increasing evapotranspiration.
