Research Groups

This study analyzed the changes in Hala Lake's area, water level, and water storage from 2011 to 2023, quantitatively assessing the influence of various driving factors. It found a significant increase in lake water storage (0.192 ± 0.009 km³/a) over the period, with precipitation-caused runoff being the key factor shaping its three distinct change stages.

Objective

• To analyze changes in the lake area, water level, and lake water storage change (LWSC) of Hala Lake from 2011 to 2023, and quantitatively assess the influence of various driving factors on the LWSC.

Study Configuration

• Spatial Scale: Hala Lake
• Temporal Scale: 2011 to 2023 (13 years)

Methodology and Data

• Models used: Hydrological and meteorological models
• Data sources: Landsat series satellites (image data), multi-source satellite altimetry data

Main Results

• Hala Lake's area, water level, and LWSC exhibited three parallel stages of change over the 13-year period:
  • 2011 to 2014: Slight lake expansion.
  • 2015 to 2019: Rapid lake expansion.
  • 2020 to 2023: Relatively stable conditions.
• Over the entire study period, the LWSC increased with a trend of 0.192 ± 0.009 km³/a.
• Contributions to total recharge input:
  • Lake surface precipitation: 51%
  • Precipitation-caused runoff: 40.96%
  • Glacier meltwater: 8.04%
• Lake surface evaporation accounted for 59.37% of the total recharge input as water loss.
• The net 40.63% of the input caused the observed LWSC increase.
• While lake surface precipitation provided the primary contribution to the Hala Lake LWSC, precipitation-caused runoff was identified as the key factor forming the three distinct stages in the LWSC.

Contributions

• Provides valuable information for the rational development and utilization of water resources by government departments.
• Contributes beneficial insights to the study of global change.
