Short Summary

This study developed a multi-objective water allocation model for Yingjisha County to optimize the utilization of groundwater with varying salinity levels, aiming to reduce overall irrigation water consumption and mitigate groundwater over-exploitation. The model successfully decreased annual irrigation water demand and enabled the use of brackish groundwater, significantly lowering the groundwater exploitation rate.

Objective

• To evaluate the potential utilization of groundwater with varying salinity levels and propose strategies for its sustainable use in Yingjisha County, an arid region facing over-mineralization due to excessive exploitation.

Study Configuration

• Spatial Scale: Yingjisha County, specifically its central part (regional/county level).
• Temporal Scale: Annual (for irrigation water allocation and exploitation rates).

Methodology and Data

• Models used:
  • Water flow and solute transport model in the unsaturated zone.
  • Multi-objective water allocation model (based on mass balance, constrained by irrigation demand and water quality).
  • Improved particle swarm optimization algorithm (for solving the allocation model).
• Data sources: Not explicitly stated in the provided text, but implied by model inputs (e.g., groundwater levels, salinity measurements, irrigation demand).

Main Results

• Optimal allocation reduced annual irrigation water consumption from 368.58 million cubic meters to 322.99 million cubic meters.
• The approach enabled the utilization of 11.64 million cubic meters of groundwater with salinity exceeding 3.0 grams per liter.
• The overall groundwater exploitation rate decreased significantly from 123% to 74%.

Contributions

• Provides a novel optimal water allocation strategy that enhances the utilization of brackish groundwater in arid regions.
• Demonstrates a method to mitigate groundwater table decline and prevent irrigation water shortages through optimized resource management.
• Offers a theoretical basis for sustainable management and efficient use of brackish groundwater for agricultural production in similar arid environments.
