Short Summary

This study investigates the synergistic effects of meteorological factors, Leaf Area Index (LAI), and irrigation on actual evapotranspiration in the Shijin irrigation district. The results highlight that LAI and irrigation are the dominant drivers, with irrigation acting synergistically with crop growth to increase evapotranspiration.

Objective

• To quantitatively assess the contributions and synergistic impact mechanisms of meteorological factors, Leaf Area Index (LAI), and irrigation on the evolution of evapotranspiration in the Shijin irrigation district.

Study Configuration

• Spatial Scale: Shijin irrigation district
• Temporal Scale: 2003–2017

Methodology and Data

• Models used: Projection pursuit model
• Data sources: Meteorological data, Leaf Area Index (LAI), and irrigation records (2003–2017)

Main Results

• A significant structural shift in evapotranspiration was identified, with the reduction in soil evaporation playing a key role in total evapotranspiration variation.
• Leaf Area Index (LAI) and irrigation were found to have the highest contribution rates to evapotranspiration.
• Irrigation primarily enhances evapotranspiration through a synergistic relationship with crop growth.

Contributions

• Addresses a gap in existing literature by explicitly incorporating irrigation activities and analyzing the synergistic effects of multiple environmental drivers on evapotranspiration in a large-scale, water-scarce region.
